Great affordable SDHC card, March 28, 2008
In the past, I bought a Transcend 8GB SDHC card for my Canon SD1000 camera. I recently bought the Transcend 16GB SDHC for my new Canon SX20IS. Both cards work very well and I've had no problems with it so far. I wanted to take this opportunity to update my review since my original review was also posted (by Amazon) for the 16GB card. This is because the only difference between these two cards is the different capacity. So, if you're in the market for an affordable high quality SDHC card, this may be the one for you. Sorry, I kind of sounded like a used car salesman right there, didn't I? I assure you that I don't work for Transcend. But, here's why I think this card is awesome:

Pros:

-Affordable!

-Large capacity

-Class 6 read/write speed (which is very fast... but is no longer the fastest class available)

-Lifetime warranty (at least that's what the package says :)

-Transcend is a reputable company that's been making memory products for a very long time. ( I swear to the tech Gods that I don't work for them!) Other reputable and reliable memory card companies include Kingston and PNY. All three of these companies have been making memory chips for many, many years.


Cons:

- I can' really think of any "Cons" about this card. But here's the 2 closest things I can come up with right now: (1) "Class 6" is no longer the fastest speed available and (2) This card does NOT make coffee for you in the morning, do your dishes for you, give you compliments when you're having a bad day, or magically improve your photography skills.




IMPORTANT SPECIAL NOTES ABOUT SDHC MEMORY CARDS:

-SDHC cards are not compatible with most older SD cameras, SD devices, or SD card readers.

-SDHC cards are rated by speed using different "classes". There are currently 4 data transfer speed classes available for SDHC cards. These classes are "class 2, class 4, and class 6, and the new class 10. For example, "Class 2" would have the slowest read/write speed while "Class 6" has the fastest read/write speed. So if you have a device in which speed may play a crucial role, make sure you buy a higher "class" SDHC card. Please note that this SDHC card no longer has the fastest read/write speed available. There is now a new class, called "Class 10". Class 6 has a minimum read/write speed of 6MB/sec... while Class 2 has minimum speed rating of 2MB/sec, and Class 4 is 4MB/sec. Starting to see the pattern?


SO WHAT'S THE DIFFERENCE BETWEEN "SD CARDS" AND "SDHC CARDS?

SDHC is basically an upgrade to the older SD cards. The reason they upgraded it was to achieve greater data transfer speeds AND capacity than previously possible with normal SD cards... and to do this, they had to redesign the card (which is why it's not compatible with normal SD devices). This was necessary because digital cameras and digital video cameras these days have higher resolutions, which equate to larger file sizes and faster data transfer needs.

Now that many digital cameras also can record HD video, you may consider getting a larger capacity card because video takes much more space than photos. The size of the video varies from camera to camera depending on what resolution and video compression the camera uses. If you plan on taking lots of video (especially HD video), I would consider getting at least a 16GB card. Check your camera specifications to see how many minutes per Gig of memory your camera can capture ...to gauge how big of a memory card you'll want to get to meet your needs.

Special Note on regular SD Cards:
If you primarily take casual photos and don't need a exceptionally fast read/write capable card, you should know that newer cameras that take "SDHC" cards will also work with older normal "SD" cards. These older cards are cheaper than the new SDHC cards, so this may be something to consider. So to sum things up, newer cameras will take SDHC and regular SD cards, but older cameras that use SD cards may not be able to use SDHC cards. This is because newer technology is usually made to be compatible with older technology (the technical term used to describe this is "backwards compatibility") ... but older technology may not have the hardware necessary to run newer tech (technical term used is "obsolete"... just kidding! ;)

I hope I haven't confused everybody by going into this much detail, but I can't help being the nerd that I am. If you are confused, don't hesitate to comment on this post and I will try my best to answer your questions. Also, any feedback is always welcome!

Conclusion: Buy the card if you have a new device that uses SDHC. It rocks! (This message has been approved by the "Duke of New Mexico")

Transcend 4 GB Class 6 SDHC Card - Good Card for SDHC Compatible Devices, May 10, 2008
UPDATE - March 2, 2010: This review was originally written for the 4 GB class 6 SDHC card, but the reviews have been grouped for all class 6 SDHC cards in the 4, 8, 16 and 32 GB sizes. All the cards should perform similarly since they are all class 6 and all made by Transcend. However, I will have to check which cards I have used hands on. I believe I only own the 4GB and 8GB cards. I will update the review further. If you have concerns regarding the 16GB or 32GB sizes, you should seek out the reviews tagged with the product links from those cards.


The Transcend 4GB SDHC CARD (Class 6) is a great card for the price. I was at first a little skeptical about the brand, but I buy way too many memory cards to ignore a good price when I see one. And I'm happy to report that I've experienced decent performance and reliability issues with this card. That's as compared to other cards I own including SanDisk, PNY and Kingston.

As long as your devices are compatible with the SDHC format, this card is a good buy. 4 GB is a nice size though I do prefer 8 GB capacity for high capacity storage.

The class 6 speed is the fastest speed available in mass market SDHC cards. Class 6 guarantees minimum transfer speeds of 6 MBs, but I've gotten speeds up to 20Mbs! That makes this card perfect for storing pictures in RAW image formats.

The Class 6 speed is on par with the Sandisk Extreme III cards that on average are about $15 to $20 more per card. If you don't have an SDHC reader, you may opt to get the package with a reader included to download your pics. If not you can just transfer your pics directly from your camera with your card still inserted. An SDHC card reader can be bought separately if your PC doesn't have a compatible slot.

General SDHC and SD Card Tips

There are a few tips that I've learned the hard way through buying TOO MANY different memory cards.
1. Make sure your device is compatible with the card! Even in regular SD cards, some older electronics aren't compatible with that large of a size (2 GB). In terms of SDHC cards, make sure your camera or other device is SDHC compatible. SDHC is different from regular SD and only newer devices tend to have built-in compatibility
2. Once you install this in your camera or device, you will generally want to format the card with your compatible device's interface. That is because the standard formats for certain devices, particularly Canon, are different from the factory installed format
3. Just like your devices, most computer SD card readers are not compatible with the SDHC format. So use a card reader or download the pictures via USB connection to the camera with the card still installed.
4. For some reason, placing the card in the locked position allows some older laptops to still read it. This is just to be used in a pinch however, and it won't apply to all systems
5. If you did not properly format your card, you may be able to save things to it and then have them "disappear." If this happens to you, make sure you use the software recovery tools BEFORE you try to save anything else to your card. That way, you can retrieve your images without over-writing them.
6. Make sure you know what you are going to use this card for. Once you have set up everything and ensured it's all compatible, you still have to decide on speed. If you are using this for storing RAW images instead of JPEGs or HD video, step up to the faster class 6 speed format if you can afford it.
7. If you are going to pay more for a faster speed, make sure your device can benefit from it. I've read, for example, that Kodak cameras are set to a fixed voltage and cannot go faster than standard speed. So the extra cash spent on Class 4, 5, or 6 is basically wasted.

Conclusion

It's great to have several extra cards on hand just in case. This 4 GB card is a nice performer. If you have a high capacity camera (10 Megapixels or more) and are storing videos or RAW images, the extra cash for the 8GB card is worth it. Or you may want to step up to the larger 16 GB size that is now available.

Enjoy!

Transcend 32 GB SDHC Review, May 25, 2009
Before you drop 120~$ for a SD card ask yourself, Do you really need 32GB card? because the card itself with same specs costs only 35$ for the 16GB version, anyway here is info that might help you

Pros :
1- Class 6 Card the(guaranteed minimum Read/write speed of 6MB/s)
2- My Test Results 18.2-18.5MB/S Read - 11.6-11.8 Write (very stable)
3- Faster than average cards and almost close to top speed SDHC cards
4- 32GB in a single small chip is awesome(You can use it as a portable HD once in a while, i share some stuff with my friends with it sometimes


Cons :
1- Expensive
2- You can get two 16GB cards for around only 70$ and save yourself 50$~
3- Slow write speeds for a 32GB card (Takes forever to fill it with DATA from PC, its not the card fault though , its just the SDHC technology is getting old and slow for 2009 standards , time for newer Tech)

* Important Info

Avoid the Sandisk Ultra Series they never reach the true marketed speed "15MB-20MB/S" its just in theory speed like how everybody knows that USB2 is much slower than its specs, and they are only Class 2 for the 32GB version which will drop frames from your HD video (Plus Class 4 is minimum requirement for shooting in HD ) if you plan to get San disk Card then get the Extreme III Series (but again from my own Tests there read speed is about 20MB not 30MB and the write speed is 14MB/s~ instead of the transcend 11MB/s write speed (Unless you spam shooting pictures with your DSLR you don't "need" faster speed)

I bought This card because i plan to take videos with my HD camcorder that last more 2 Hours, if you do not plan to shoot for longtime then you are better with getting the 16GB card HOWEVER, if you are lazy like my mom and do not plan to transfer DATA from the card to Your computer HD after every trip, then get the 32GB card.or you gonna end up on a trip and a message pops "No memory"

If you plan to shoot for longer time, check your camcorder battery too does it even last that long? so be sure about that before you drop over 100$ for this card

product failed., July 26, 2009
Well, it was great while it lasted. Unfortunately, it did not last long.

Like other reviewers, after <20 use cycles the device failed and I got a "lock" error when, in fact, the write-protection lock was not engaged. Oddly, by engaging the lock (i.e. entering read-only mode) I was able to remove the picture files from the card. Obviously, further use in the camera was impossible; I was also unable to reformat the card (either with my camera or with the SD Associations free software [..]).

This card has a high average rating but I would urge customers to consider the number of 1-star ratings due to complete product failure before they purchase this item.

My Canon loves the 8 GB SDHC card, January 15, 2008
I recently purchased a Canon Powershot A720IS digital camera that is capable of recognizing and using up to 2 TERRABYTES of memory card (in the future) so I wanted to get the largest memory card I could install for now. I wanted to use the camera both on dry land and with an underwater housing for shooting stills and video on dive trips. Camera specs said an 8 GB SDHC card would record one hour of hi res video at 30 fps. Or nearly 2300 hi res stills at 8 megapixels.

A test of the Transcend 8GB SDHC card in the camera ended up shooting 70 minutes of full screen, 30fps digital video that could not be distinguished from my DV camcorder video quality. Playback from the memory card to the TV was so fast & efficient there was never a single "stutter" on the screen. The card speed is genuinely FAST as advertised. Low level formatting of the card allowed for very acceptable rapid-fire sequential still photo shooting speeds when light levels were bright enough that the flash was not needed/used. Something like 2 photos every 3 seconds. Files were flawless in display, both for stills and video.

This product was significantly lower in price than the Kingston 8GB SDHC card I originally bought with the camera. I've used both interchangeably and cannot see any different in the speed or capacity and quality of imagery is identical. For the money I'll stick with Transcend and am looking forward to getting their 16GB card once the price drops substantially below the $100 mark. That would provide nearly 2 1/2 hours of video on my still camera or 4600 highest quality stills. I'm afraid my camcorder will be collecting dust much of the time. A big advantage to video on the card is there are NO MOVING PARTS, e.g. a mini DV tape cassette and camcorder or VCR playback unit needed to dump the video and stills to my Mac for editing and burning DVDs. I just stick the card in the MicroMate USB card reader, plug it in the computer and bingo, ready to sort thru and dump to the hard drive. Since the card is formatted by a Canon camera it automatically boots up the Canon Viewer software too. That should work the same for other brands of still cameras formatting this chip.

The Fastest Card at This Price But..., June 26, 2007
This SDHC card is the fastest one in its price range but it may cause your images to be lost.

I use two of this in a Canon SD750. After the first use, all of the images were lost. (But thank God, I could rescue them with Lexar Image Rescue 2, a program better than its competitors) Then I formated the card(s) in the camera(s) with "low level format" option several times and there has been no problem after that so far.

I can suggest these points to potential owners of this card:
1- Use it very carefully, make backups if possible.
2- Format it several times before the first use with "low level format" option.
3- If you loose your images, don't panic. At this situation, It is very important not to take anymore pictures. If you take pictures after this point, you can overwrite your lost images and there can be no chance to get them back. Connect your card to your computer with a card reader (SDHC Compatible) and rescue them with Lexar Image Rescue.

Excellent Mini Hard Drive equivalent, December 11, 2007
This card is able to hold a complete DVD movie, thousands of songs/photos, or just serve as a backup device for one's files.

It operates very well - I now have purchased 3 and with each use its value becomes more apparent.

One word of caution - even though most laptops and systems have an SD card slot, older computers may not be able to recognize or write to this card. Make sure your system has the ability to read SDHC configured products.

If you do not have an SD slot you can purchase an tiny SD reader (very inexpensive) that plugs into your USB port.

Great value, just be careful..., January 2, 2009
I recently ordered this card as an accessory for my Acer Aspire One netbook PC. The card took a little while to ship, about 8 days, but that wasn't a big deal. The card has lots of space, and the read speeds are quite impressive. I mostly use it to run and store portable software, and it does a very good job at that.

My only complaint is that when I first inserted the card into my PC it attempted to install some adware. The program was from a company called RelevantKnowledge, and they gather your information for market research purposes. Luckily my spyware software picked it up immediately,so I was able to delete it. Afterward I formatted the card, and now I'm happy as can be.

Reliable card, good speeds!, December 4, 2008
Transcend 16 GB SDHC SD Class 6 Flash Memory Card TS16GSDHC6E [Amazon Frustration-Free Packaging]
I have 4 of these cards that I use in my Panasonic HMC-150, a professional grade video camera. I've run read/write tests on all of them and they get about 14 MB/s write speeds and 17.5 MB/s read speeds. Never encountered any errors! These cards are the best bang for your buck, and the frustration free packaging is awesome.

Don't Let This Happen to You....., August 3, 2008
It's great to have 8GB of memory but it is a double edged sword. Today after using this card for only the second time, it failed on me. I lost almost 200 precious images - gone forever. I am what you would call an enthusiast or hobbyist. I love photography and spend every spare minute, which is very seldom these days, pursuing my passion. So I do a fair amount of experimentation. These cards are great when they work - but if they fail you even once - the results can be catastrophic. Maybe I am the unlucky 1 of 250 reviewers with a bad experience with this product, but I feel it is my responsibility to report this to everyone. I hope it never happens to you. It is human nature for me to wonder, if I had spent a few more dollars for a better brand name, would my photos be intact today?

(But thank God, I could rescue them with Lexar Image Rescue 2, a program better than its competitors) Then I formated the card(s) in the camera(s) with "low level format" option several times and there has been no problem after that so far.

I can suggest these points to potential owners of this card:
1- Use it very carefully, make backups if possible.
2- Format it several times before the first use with "low level format" option.
3- If you loose your images, don't panic. At this situation, It is very important not to take anymore pictures. If you take pictures after this point, you can overwrite your lost images and there can be no chance to get them back. Connect your card to your computer with a card reader (SDHC Compatible) and rescue them with Lexar Image Rescue.

Excellent Mini Hard Drive equivalent, December 11, 2007
This card is able to hold a complete DVD movie, thousands of songs/photos, or just serve as a backup device for one's files.

It operates very well - I now have purchased 3 and with each use its value becomes more apparent.

One word of caution - even though most laptops and systems have an SD card slot, older computers may not be able to recognize or write to this card. Make sure your system has the ability to read SDHC configured products.

If you do not have an SD slot you can purchase an tiny SD reader (very inexpensive) that plugs into your USB port.

Great value, just be careful..., January 2, 2009
I recently ordered this card as an accessory for my Acer Aspire One netbook PC. The card took a little while to ship, about 8 days, but that wasn't a big deal. The card has lots of space, and the read speeds are quite impressive. I mostly use it to run and store portable software, and it does a very good job at that.

My only complaint is that when I first inserted the card into my PC it attempted to install some adware. The program was from a company called RelevantKnowledge, and they gather your information for market research purposes. Luckily my spyware software picked it up immediately,so I was able to delete it. Afterward I formatted the card, and now I'm happy as can be.

Reliable card, good speeds!, December 4, 2008
Transcend 16 GB SDHC SD Class 6 Flash Memory Card TS16GSDHC6E [Amazon Frustration-Free Packaging]
I have 4 of these cards that I use in my Panasonic HMC-150, a professional grade video camera. I've run read/write tests on all of them and they get about 14 MB/s write speeds and 17.5 MB/s read speeds. Never encountered any errors! These cards are the best bang for your buck, and the frustration free packaging is awesome.

Don't Let This Happen to You....., August 3, 2008
It's great to have 8GB of memory but it is a double edged sword. Today after using this card for only the second time, it failed on me. I lost almost 200 precious images - gone forever. I am what you would call an enthusiast or hobbyist. I love photography and spend every spare minute, which is very seldom these days, pursuing my passion. So I do a fair amount of experimentation. These cards are great when they work - but if they fail you even once - the results can be catastrophic. Maybe I am the unlucky 1 of 250 reviewers with a bad experience with this product, but I feel it is my responsibility to report this to everyone. I hope it never happens to you. It is human nature for me to wonder, if I had spent a few more dollars for a better brand name, would my photos be intact today? ... Read more

Not All Class 10 Cards are Equal, April 11, 2010
UPDATE 9-10 I own 4 of these cards now. I have more of these than any other card I own because the are a very good value for capacity/price/and speed. My initial dissapointment over the lack of super high speed is outweighed by the reality that this card is an exceptional value.

Origional Review:
I purchased this card making the assumption that all class 10 cards had the same read and write speed. This was a poor assumption on my part.

The product photo on Amazon does not have the card's speed printed on it. The card that was shipped shows the front of the card printed with "20MB/s" which is the cards read speed. The cards write speed is only 16MB/s.

I own a SanDisk Extreme III class 10 card that has (up to) 30MB/s read and write speed. My Nikon D-90 that can take advantage of the SanDisk cards speed. The difference is the SanDisk card can capture 100 photos at fine resolution in 24 seconds. The Transcend card captures 66 photos in the same time/resolution.

I reality very few people will ever have the need to drill off 100 photos in 24 seconds, but I can't stand to loose a good shot because the camera is slow while writing to the card and I can't fire the shutter. You can hear this happen at about 4.5 seconds in the video review. This does not happen with the SanDisk class 10 30MB/s card.

A lot can happen in a fraction of a second that can make a shot good or bad and the having ability to fire a lot of shots in rapid succession is important to me.

If you own an SLR that is capable of rapid fire, high-resolution photography you may want to consider the SanDisk Extreme III 30 MB/s card.

If you own a compact digital camera, this card will exceed the capabilities of all of them. For compact cameras the card isn't usually the slowest part of the data write process, it's the camera.

This card is reasonably priced for a class 10 card. Just know what you are getting, what your needs may be, and what else is available. I own other Transcend cards and they have always worked properly without any issues.

The video that I attached shows this card with the same 24 seconds that I gave the SanDisk Card.

Sandisk SDSDX3-008G-E31 8GB Extreme III SD Card 30MB/s (RETAIL PACKAGE)

Fast!, April 8, 2010
I purchased this for use with my new Canon T2i. I use it primarily for shooting full resolution 1080p video, although I shoot stills as well.

The camera choked on the class 4 chip that I originally purchased, but with this one, it is amazing. I can shoot rapidfire 18 megapixel stills (I've tested it up to 30+ shots in a row), and there is no lag. I've never had an error when shooting hi-def video.

Highly recommended! I'm buying another one.

Fast, fast, fast!, March 15, 2010
I bought this card for my Canon T1i. The card I had been using before ordering this one was a Kingston Class 6 micro sd card and it worked well enough for the type of shooting I did. Class 6 was the card speed that Canon recommended when I bought my T1i (Class 10 cards were not yet available) and it seemed fast enough for the way I used my camera - isolated single photos taken at Medium (8 MP) or Large (15 MP) jpg settings and 1280 x 720 video. And while I ocassionally took continuous photos, I had never much exceeded 5-10 photos in a row and had never run into a problem with my Class 6 card.

When I first saw the Class 10 cards I did some experiments with my camera. How many continuous Large photos could I take before the camera slowed down? It turned out to be about 30. And how many RAW photos could I take before the camera slowed down? It turned out to be about 9. SInce I did not generally take any photos in RAW and never needed more than about 10 continuous photos at Large, the Class 6 card seemed more than sufficient for my needs. But I wondered about the speed of the Class 10 cards enough that I finally bought one.

It turns out that the Class 10 card is sufficiently fast that there does not seem to be a reasonable upper limit on single Large photos. I have taken 60 on continuous without an issue. And although I still cannot take more than 9 RAW photos on continuous with the Class 10 card, when I am finished taking those photos the camera no longer displays a Wait - writing pictures screen. The RAW photos get written from the built-in memory to the card so quickly that the camera does not need to display the Wait screen.

So this card is fast! Given the way I take photos this purchase was unnecessary, but still I am glad I bought it. I know I will not run into a situation where speed is an issue with this card.

Transcend vs Sandisk of equal price, July 31, 2010
OK. this card was around $47 for a class 10 16gb. The other card i bought was a Sandisk class 10 8gb for the around same price. I did a 10 sec stop watch test on both cards with my Rebel T1i on raw and the Sandisk was only faster by 1 shot in a 10 sec burst. to me it seems trivial to pay 47 bucks for a Sandisk 8gig when you can get 16 gigs for the same price. yes i know, the Sandisk is good for arctic and desert temperatures... but i live in western NY... not Antarctica or the Sahara. If your looking for a good card, with more gigs for your buck, the Transcend is well worth it.

Slower than slow on Pentax K-x, April 25, 2010
I bought this for my pentax K-x but it would randomly corrupt images. Also, it was slower than my 3+ year old SandDisk Ultra 1GB card. I was told by the seller (Thememstore) that others with the k-x have had the same problems. So apparently it must have something to do with the class 10 part, because since I returned this card I bought a SandDisk Extreme III 4GB Class 6 and it works far better.

Would I recommend this card? Yes, but only to someone who knows that class 10 will work in their camera. I don't fault the card as I think the problem is with the K-x.

DESTROYS DATA -- after working fine for just long enough to fool you!, November 6, 2010
SUMMARY:


DO NOT BUY THIS CARD UNLESS YOU WANT TO PLAY RUSSIAN ROULETTE WITH YOUR DATA. Card worked fine when I bought it, but malfunctioned within the first 400 photos -- malfunctioned so badly that some very technical tools were needed to recover anything at all, and some photos were still permanently lost. Recovering the data requires the attention of a serious data recovery expert or someone with substantial technical knowledge and lots of time.


DETAILS:

I made the mistake buying this card for my camera right before a long trip overseas. It worked fine on the first few dozen shots. I didn't see any improvement in speed over my trusty 1.5-year-old Transcend 8GB Class-6 card, but that was most likely because the camera itself (Canon EOS Rebel 1000D/XSi) could not write images any faster than that (full-size JPEG, continuous shutter mode, roughly did ~2.5-3 images/second on both cards, with no slowdown after the first few shots).

200 shots or so into using this card, I get a sudden mysterious message from the camera when I try to take a new shot -- Card Format Invalid (never saw it in the previous 1.5 years on this camera with 3 other SDHC cards). I look around for a bit, and discover that turning the camera off, pulling the card out and putting it back in is enough to clear the error message, and the previous photos are still visible.

I then make the mistake of assuming the problem is just that -- needing to "reboot" the camera when the card is acting stupid, and nothing else. Over the next 200 or so shots, this problem comes up every 50 shots or so. Then, after yet another "reboot", I notice that the camera's playback function is only showing the last 30 photos!!! Yet it shows that there's only 5.7G of space left on the camera -- the other 2G+ _should_ be taken up by the photos I've shot thus far, but the playback doesn't show them.

And this happens in the middle of a trek through the Peruvian Andes, several days' walk/horse ride from the first village with electricity, let alone a computer (with lots of once-in-a-lifetime shots on the camera). I pull this card out immediately, plug in my backup card, and wait until coming back to civilization to take a look at the card. Sure enough, the card is severely corrupted -- the directory listing is showing a bunch of folders with weird-character names, and only the last ~30 photos are visible from the computer, too!


RECOVERY SUGGESTIONS:

Hopefully you'll read this before buying and will not buy this piece of junk card. If you had the misfortune of running into the same problem and losing your data, read on.

I have now had time to examine what was left on the card, using tools that are not easily usable to people without substantial technical training. I've managed to recover over 90% of my photos, but this was NOT easy, and I suspect that even some shops specializing in data recovery from failed disks may not know how to get your data back -- this is NOT as simple as just undeleting a file!

Non-technical instructions:

1. As soon as you see the FIRST error involving the card format, turn off the camera, pull out the card, and copy all of your photos to a different device (computer/harddrive/whatnot). The earlier you stop using this card, the safer your photos will be.

2. As soon as the first problem happens, move the little plastic slider on the side of the card to the "Lock" position -- this will prevent anything else from being written on the card, which lowers the risk of what's left of your photos being overwritten.

3. If you see directories (aka folders) with weird names when you plug this card into a computer -- or see a huge number of photos missing when you look at them on the camera, take the card out IMMEDIATELY, and take the card to a data recovery shop or a technical expert willing to look at the card in depth. Give them a printout of the explanation below.


Technical details:

At least in my case, the filesystem was indeed somehow damaged, perhaps by the camera deciding to write over the location of the root directory somehow. I took a full disk image of the card, and operated on the disk image only (there were no read errors when making the image, FWIW). Somehow I was lucky enough to have the original _subdirectories_ \DCIM and \DCIM\100CANON survive on the card intact even though the root directory structure now pointed to a different, new, place on the filesystem as \DCIM.

I found the location of the old 100CANON directory on the filesystem by searching for one of the filenames I knew would exist in the old directory, like IMG_7000, across the whole disk image.

I then edited the filesystem (yea, with a hex editor!) to have the new \DCIM directory point to the old 100CANON subdirectory. See the Wikipedia article on FAT32 for a reasonably easy reference on how to find the 4 bytes that need to be edited, and how to calculate the correct updated value.

Mounting the edited disk image (with Linux's 'mount -t loop'), the directory was intact, and all but about 5% of the photos were completely intact as well -- the remainder must have been overwritten after the directory structure got corrupted. Depending on how long it takes the user to notice a problem, of course, much more damage could easily happen to the original data.

Here's one easy hack to see how much you can hope to recover, if you're recovering camera data. The same trick may be useful for locating the JPEGs if the original image-containing directory is no longer intact (good luck with recovery then! I thankfully didn't have to do this). Take any image produced by the same camera, look at its JFIF headers. My camera leaves the string "Canon EOS DIGITAL REBEL XS" in two places in every JPEG it creates, early on in the JFIF header. Search for that string across the whole filesystem. If there's, say, 500 hits, that means you can hope for [easy] recovery of at most 250 photos -- any photo that is missing the JFIF headers will be missing the first chunk of the file, and will make it very hard both to find _and_ to reconstruct the remaining data, if any, into a usable JPEG (I have not tried to do this, at least, and it seems very hard).

Transcend Vs. Sandisk on Panasonic LX5, November 12, 2010
I will be writing this review for both SanDisk Extreme SDHC class 10 8gb and Transcend SDHC class 10 16gb.

I bought SanDisk class 10 and Transcend class 10 for my new Panasonic LX5. I got both card because no one really did a comparison with a compact camera and I was just going crazy trying to see if there is any big difference between the 2 cards.

SanDisk Extreme package box indicated it's water proof, x-ray proof, shock proof, temperature proof. I am not ready to spend $50 to see if it really stand up to it's words. And I don't think normal people would go through the extreme condition in taking pictures or videos.

Cut the story short, I really want to see if there is any difference in writing performance between the 2 cards in a compact camera. There is a continuous burst mode in LX5 and the manual indicated it is only limited by the condition of picture environment and performance of the SD card. Within the mode there are 2 different settings:1) speed priority or 2) picture/quality priority. The shutter speed is much faster with speed priority compare to picture priority.

I first formatted both cards out of box then put each card in series of test(3 rounds each setting for each card) shooting at the same object under same lighting condition. The results:
Speed Priority:
SanDisk Class 10 8gb
22-33 shots before camera stopped to allow the card to catch up with writing.

Transcend Class 10 16gb
22-24 shots before camera stopped to allow the card to catch up with writing.

Picture priority
SanDisk Class 10 8gb
34-46 shots before camera stopped

Transcend Class 10 16gb
27-33 shots before camera stopped


It seems that at a higher shutter speed, both cards performed very similar under the same shooting condition. But at a slower shutter speed the SanDisk definitely out perform Transcend. I hope this little experiment satisfied anyone with curiosity like me. Transcend definitely is a bargain with 16gb and almost half of the price compare to SanDisk. But I am going to use SanDisk Extreme as my primary card and Transcend as backup or on a second camera to ensure i would not miss any shots.

Depend on what you will use it for ..., October 13, 2010
The "C10" is for "minimum sustaining speed" of 10mbps. The sustaining speed is critical if you're using for HD camcorder. There is other brand card that is also c10 but it costs more (2x) for its print of 30mbps on the card. It leads consumers into thinking that the higher price is worth for the 30mbps. However, the 30mbps is the "burst" speed. Burst speed is critical for HD camera and for doing copies. I have a HD camcorder and I'm very satisfied with this card after many hours for recording. I bought this card to do 100% of recording so it is the right price. I would buy the other high price brand card of 30mbps if I will do a lot of picture taking. The bottom line is to buy for the purpose of your usage.

Not very fast, April 14, 2010
On my Panasonic GF1, it's the same speed as a Class 6 Transcend card and much slower than a Class 10 SanDisk Extreme. Buy the Transcend Class 6 if you want to save money or the SanDisk if you wan speed, but skip this one.

I took a full disk image of the card, and operated on the disk image only (there were no read errors when making the image, FWIW). Somehow I was lucky enough to have the original _subdirectories_ \DCIM and \DCIM\100CANON survive on the card intact even though the root directory structure now pointed to a different, new, place on the filesystem as \DCIM.

I found the location of the old 100CANON directory on the filesystem by searching for one of the filenames I knew would exist in the old directory, like IMG_7000, across the whole disk image.

I then edited the filesystem (yea, with a hex editor!) to have the new \DCIM directory point to the old 100CANON subdirectory. See the Wikipedia article on FAT32 for a reasonably easy reference on how to find the 4 bytes that need to be edited, and how to calculate the correct updated value.

Mounting the edited disk image (with Linux's 'mount -t loop'), the directory was intact, and all but about 5% of the photos were completely intact as well -- the remainder must have been overwritten after the directory structure got corrupted. Depending on how long it takes the user to notice a problem, of course, much more damage could easily happen to the original data.

Here's one easy hack to see how much you can hope to recover, if you're recovering camera data. The same trick may be useful for locating the JPEGs if the original image-containing directory is no longer intact (good luck with recovery then! I thankfully didn't have to do this). Take any image produced by the same camera, look at its JFIF headers. My camera leaves the string "Canon EOS DIGITAL REBEL XS" in two places in every JPEG it creates, early on in the JFIF header. Search for that string across the whole filesystem. If there's, say, 500 hits, that means you can hope for [easy] recovery of at most 250 photos -- any photo that is missing the JFIF headers will be missing the first chunk of the file, and will make it very hard both to find _and_ to reconstruct the remaining data, if any, into a usable JPEG (I have not tried to do this, at least, and it seems very hard).

Transcend Vs. Sandisk on Panasonic LX5, November 12, 2010
I will be writing this review for both SanDisk Extreme SDHC class 10 8gb and Transcend SDHC class 10 16gb.

I bought SanDisk class 10 and Transcend class 10 for my new Panasonic LX5. I got both card because no one really did a comparison with a compact camera and I was just going crazy trying to see if there is any big difference between the 2 cards.

SanDisk Extreme package box indicated it's water proof, x-ray proof, shock proof, temperature proof. I am not ready to spend $50 to see if it really stand up to it's words. And I don't think normal people would go through the extreme condition in taking pictures or videos.

Cut the story short, I really want to see if there is any difference in writing performance between the 2 cards in a compact camera. There is a continuous burst mode in LX5 and the manual indicated it is only limited by the condition of picture environment and performance of the SD card. Within the mode there are 2 different settings:1) speed priority or 2) picture/quality priority. The shutter speed is much faster with speed priority compare to picture priority.

I first formatted both cards out of box then put each card in series of test(3 rounds each setting for each card) shooting at the same object under same lighting condition. The results:
Speed Priority:
SanDisk Class 10 8gb
22-33 shots before camera stopped to allow the card to catch up with writing.

Transcend Class 10 16gb
22-24 shots before camera stopped to allow the card to catch up with writing.

Picture priority
SanDisk Class 10 8gb
34-46 shots before camera stopped

Transcend Class 10 16gb
27-33 shots before camera stopped


It seems that at a higher shutter speed, both cards performed very similar under the same shooting condition. But at a slower shutter speed the SanDisk definitely out perform Transcend. I hope this little experiment satisfied anyone with curiosity like me. Transcend definitely is a bargain with 16gb and almost half of the price compare to SanDisk. But I am going to use SanDisk Extreme as my primary card and Transcend as backup or on a second camera to ensure i would not miss any shots.

Depend on what you will use it for ..., October 13, 2010
The "C10" is for "minimum sustaining speed" of 10mbps. The sustaining speed is critical if you're using for HD camcorder. There is other brand card that is also c10 but it costs more (2x) for its print of 30mbps on the card. It leads consumers into thinking that the higher price is worth for the 30mbps. However, the 30mbps is the "burst" speed. Burst speed is critical for HD camera and for doing copies. I have a HD camcorder and I'm very satisfied with this card after many hours for recording. I bought this card to do 100% of recording so it is the right price. I would buy the other high price brand card of 30mbps if I will do a lot of picture taking. The bottom line is to buy for the purpose of your usage.

Not very fast, April 14, 2010
On my Panasonic GF1, it's the same speed as a Class 6 Transcend card and much slower than a Class 10 SanDisk Extreme. Buy the Transcend Class 6 if you want to save money or the SanDisk if you wan speed, but skip this one.

Not All Class 10 Cards are Equal, April 11, 2010
UPDATE 9-10 I own 4 of these cards now. I have more of these than any other card I own because the are a very good value for capacity/price/and speed. My initial dissapointment over the lack of super high speed is outweighed by the reality that this card is an exceptional value.

Origional Review:
I purchased this card making the assumption that all class 10 cards had the same read and write speed. This was a poor assumption on my part.

The product photo on Amazon does not have the card's speed printed on it. The card that was shipped shows the front of the card printed with "20MB/s" which is the cards read speed. The cards write speed is only 16MB/s.

I own a SanDisk Extreme III class 10 card that has (up to) 30MB/s read and write speed. My Nikon D-90 that can take advantage of the SanDisk cards speed. The difference is the SanDisk card can capture 100 photos at fine resolution in 24 seconds. The Transcend card captures 66 photos in the same time/resolution.

I reality very few people will ever have the need to drill off 100 photos in 24 seconds, but I can't stand to loose a good shot because the camera is slow while writing to the card and I can't fire the shutter. You can hear this happen at about 4.5 seconds in the video review. This does not happen with the SanDisk class 10 30MB/s card.

A lot can happen in a fraction of a second that can make a shot good or bad and the having ability to fire a lot of shots in rapid succession is important to me.

If you own an SLR that is capable of rapid fire, high-resolution photography you may want to consider the SanDisk Extreme III 30 MB/s card.

If you own a compact digital camera, this card will exceed the capabilities of all of them. For compact cameras the card isn't usually the slowest part of the data write process, it's the camera.

This card is reasonably priced for a class 10 card. Just know what you are getting, what your needs may be, and what else is available. I own other Transcend cards and they have always worked properly without any issues.

The video that I attached shows this card with the same 24 seconds that I gave the SanDisk Card.

Sandisk SDSDX3-008G-E31 8GB Extreme III SD Card 30MB/s (RETAIL PACKAGE)

Fast!, April 8, 2010
I bought this for my pentax K-x but it would randomly corrupt images. Also, it was slower than my 3+ year old SandDisk Ultra 1GB card. I was told by the seller (Thememstore) that others with the k-x have had the same problems. So apparently it must have something to do with the class 10 part, because since I returned this card I bought a SandDisk Extreme III 4GB Class 6 and it works far better.

Would I recommend this card? Yes, but only to someone who knows that class 10 will work in their camera. I don't fault the card as I think the problem is with the K-x.

DESTROYS DATA -- after working fine for just long enough to fool you!, November 6, 2010
SUMMARY:


DO NOT BUY THIS CARD UNLESS YOU WANT TO PLAY RUSSIAN ROULETTE WITH YOUR DATA. Card worked fine when I bought it, but malfunctioned within the first 400 photos -- malfunctioned so badly that some very technical tools were needed to recover anything at all, and some photos were still permanently lost. Recovering the data requires the attention of a serious data recovery expert or someone with substantial technical knowledge and lots of time.


DETAILS:

I made the mistake buying this card for my camera right before a long trip overseas. It worked fine on the first few dozen shots. I didn't see any improvement in speed over my trusty 1.5-year-old Transcend 8GB Class-6 card, but that was most likely because the camera itself (Canon EOS Rebel 1000D/XSi) could not write images any faster than that (full-size JPEG, continuous shutter mode, roughly did ~2.5-3 images/second on both cards, with no slowdown after the first few shots).

200 shots or so into using this card, I get a sudden mysterious message from the camera when I try to take a new shot -- Card Format Invalid (never saw it in the previous 1.5 years on this camera with 3 other SDHC cards). I look around for a bit, and discover that turning the camera off, pulling the card out and putting it back in is enough to clear the error message, and the previous photos are still visible.

I then make the mistake of assuming the problem is just that -- needing to "reboot" the camera when the card is acting stupid, and nothing else. Over the next 200 or so shots, this problem comes up every 50 shots or so. Then, after yet another "reboot", I notice that the camera's playback function is only showing the last 30 photos!!! Yet it shows that there's only 5.7G of space left on the camera -- the other 2G+ _should_ be taken up by the photos I've shot thus far, but the playback doesn't show them.

And this happens in the middle of a trek through the Peruvian Andes, several days' walk/horse ride from the first village with electricity, let alone a computer (with lots of once-in-a-lifetime shots on the camera). I pull this card out immediately, plug in my backup card, and wait until coming back to civilization to take a look at the card. Sure enough, the card is severely corrupted -- the directory listing is showing a bunch of folders with weird-character names, and only the last ~30 photos are visible from the computer, too!


RECOVERY SUGGESTIONS:

Hopefully you'll read this before buying and will not buy this piece of junk card. If you had the misfortune of running into the same problem and losing your data, read on.

I have now had time to examine what was left on the card, using tools that are not easily usable to people without substantial technical training. I've managed to recover over 90% of my photos, but this was NOT easy, and I suspect that even some shops specializing in data recovery from failed disks may not know how to get your data back -- this is NOT as simple as just undeleting a file!

Non-technical instructions:

1. As soon as you see the FIRST error involving the card format, turn off the camera, pull out the card, and copy all of your photos to a different device (computer/harddrive/whatnot). The earlier you stop using this card, the safer your photos will be.

2. As soon as the first problem happens, move the little plastic slider on the side of the card to the "Lock" position -- this will prevent anything else from being written on the card, which lowers the risk of what's left of your photos being overwritten.

3. If you see directories (aka folders) with weird names when you plug this card into a computer -- or see a huge number of photos missing when you look at them on the camera, take the card out IMMEDIATELY, and take the card to a data recovery shop or a technical expert willing to look at the card in depth. Give them a printout of the explanation below.


Technical details:

At least in my case, the filesystem was indeed somehow damaged, perhaps by the camera deciding to write over the location of the root directory somehow.

Fast!, April 8, 2010
I purchased this for use with my new Canon T2i. I use it primarily for shooting full resolution 1080p video, although I shoot stills as well.

The camera choked on the class 4 chip that I originally purchased, but with this one, it is amazing. I can shoot rapidfire 18 megapixel stills (I've tested it up to 30+ shots in a row), and there is no lag. I've never had an error when shooting hi-def video.

Highly recommended! I'm buying another one.

Fast, fast, fast!, March 15, 2010
I bought this card for my Canon T1i. The card I had been using before ordering this one was a Kingston Class 6 micro sd card and it worked well enough for the type of shooting I did. Class 6 was the card speed that Canon recommended when I bought my T1i (Class 10 cards were not yet available) and it seemed fast enough for the way I used my camera - isolated single photos taken at Medium (8 MP) or Large (15 MP) jpg settings and 1280 x 720 video. And while I ocassionally took continuous photos, I had never much exceeded 5-10 photos in a row and had never run into a problem with my Class 6 card.

When I first saw the Class 10 cards I did some experiments with my camera. How many continuous Large photos could I take before the camera slowed down? It turned out to be about 30. And how many RAW photos could I take before the camera slowed down? It turned out to be about 9. SInce I did not generally take any photos in RAW and never needed more than about 10 continuous photos at Large, the Class 6 card seemed more than sufficient for my needs. But I wondered about the speed of the Class 10 cards enough that I finally bought one.

It turns out that the Class 10 card is sufficiently fast that there does not seem to be a reasonable upper limit on single Large photos. I have taken 60 on continuous without an issue. And although I still cannot take more than 9 RAW photos on continuous with the Class 10 card, when I am finished taking those photos the camera no longer displays a Wait - writing pictures screen. The RAW photos get written from the built-in memory to the card so quickly that the camera does not need to display the Wait screen.

So this card is fast! Given the way I take photos this purchase was unnecessary, but still I am glad I bought it. I know I will not run into a situation where speed is an issue with this card.

Transcend vs Sandisk of equal price, July 31, 2010
OK. this card was around $47 for a class 10 16gb. The other card i bought was a Sandisk class 10 8gb for the around same price. I did a 10 sec stop watch test on both cards with my Rebel T1i on raw and the Sandisk was only faster by 1 shot in a 10 sec burst. to me it seems trivial to pay 47 bucks for a Sandisk 8gig when you can get 16 gigs for the same price. yes i know, the Sandisk is good for arctic and desert temperatures... but i live in western NY... not Antarctica or the Sahara. If your looking for a good card, with more gigs for your buck, the Transcend is well worth it.

Transcend Vs. Sandisk on Panasonic LX5, November 12, 2010
I will be writing this review for both SanDisk Extreme SDHC class 10 8gb and Transcend SDHC class 10 16gb.

I bought SanDisk class 10 and Transcend class 10 for my new Panasonic LX5. I got both card because no one really did a comparison with a compact camera and I was just going crazy trying to see if there is any big difference between the 2 cards.

SanDisk Extreme package box indicated it's water proof, x-ray proof, shock proof, temperature proof. I am not ready to spend $50 to see if it really stand up to it's words. And I don't think normal people would go through the extreme condition in taking pictures or videos.

Cut the story short, I really want to see if there is any difference in writing performance between the 2 cards in a compact camera. There is a continuous burst mode in LX5 and the manual indicated it is only limited by the condition of picture environment and performance of the SD card. Within the mode there are 2 different settings:1) speed priority or 2) picture/quality priority. The shutter speed is much faster with speed priority compare to picture priority.

I first formatted both cards out of box then put each card in series of test(3 rounds each setting for each card) shooting at the same object under same lighting condition. The results:
Speed Priority:
SanDisk Class 10 8gb
22-33 shots before camera stopped to allow the card to catch up with writing.

Transcend Class 10 16gb
22-24 shots before camera stopped to allow the card to catch up with writing.

Picture priority
SanDisk Class 10 8gb
34-46 shots before camera stopped

Transcend Class 10 16gb
27-33 shots before camera stopped


It seems that at a higher shutter speed, both cards performed very similar under the same shooting condition. But at a slower shutter speed the SanDisk definitely out perform Transcend. I hope this little experiment satisfied anyone with curiosity like me. Transcend definitely is a bargain with 16gb and almost half of the price compare to SanDisk. But I am going to use SanDisk Extreme as my primary card and Transcend as backup or on a second camera to ensure i would not miss any shots.

Depend on what you will use it for ..., October 13, 2010
The "C10" is for "minimum sustaining speed" of 10mbps. The sustaining speed is critical if you're using for HD camcorder. There is other brand card that is also c10 but it costs more (2x) for its print of 30mbps on the card. It leads consumers into thinking that the higher price is worth for the 30mbps. However, the 30mbps is the "burst" speed. Burst speed is critical for HD camera and for doing copies. I have a HD camcorder and I'm very satisfied with this card after many hours for recording. I bought this card to do 100% of recording so it is the right price. I would buy the other high price brand card of 30mbps if I will do a lot of picture taking. The bottom line is to buy for the purpose of your usage.

Not very fast, April 14, 2010
On my Panasonic GF1, it's the same speed as a Class 6 Transcend card and much slower than a Class 10 SanDisk Extreme. Buy the Transcend Class 6 if you want to save money or the SanDisk if you wan speed, but skip this one.

Class 10 pricing for Class 6 performance, June 10, 2010
Ran some of my own informal tests of this card pitted against an older well used Transcend Class 6 card. The older cheaper card equalled or beat this "Class 10" card. Shop for the best priced Class 6 card right now or pay the premium for real Class 10 performance.

Great affordable SDHC card, March 28, 2008
In the past, I bought a Transcend 8GB SDHC card for my Canon SD1000 camera. I recently bought the Transcend 16GB SDHC for my new Canon SX20IS. Both cards work very well and I've had no problems with it so far. I wanted to take this opportunity to update my review since my original review was also posted (by Amazon) for the 16GB card. This is because the only difference between these two cards is the different capacity. So, if you're in the market for an affordable high quality SDHC card, this may be the one for you. Sorry, I kind of sounded like a used car salesman right there, didn't I? I assure you that I don't work for Transcend. But, here's why I think this card is awesome:

Pros:

-Affordable!

-Large capacity

-Class 6 read/write speed (which is very fast... but is no longer the fastest class available)

-Lifetime warranty (at least that's what the package says :)

-Transcend is a reputable company that's been making memory products for a very long time. ( I swear to the tech Gods that I don't work for them!) Other reputable and reliable memory card companies include Kingston and PNY. All three of these companies have been making memory chips for many, many years.


Cons:

- I can' really think of any "Cons" about this card. But here's the 2 closest things I can come up with right now: (1) "Class 6" is no longer the fastest speed available and (2) This card does NOT make coffee for you in the morning, do your dishes for you, give you compliments when you're having a bad day, or magically improve your photography skills.




IMPORTANT SPECIAL NOTES ABOUT SDHC MEMORY CARDS:

-SDHC cards are not compatible with most older SD cameras, SD devices, or SD card readers.

-SDHC cards are rated by speed using different "classes". There are currently 4 data transfer speed classes available for SDHC cards. These classes are "class 2, class 4, and class 6, and the new class 10. For example, "Class 2" would have the slowest read/write speed while "Class 6" has the fastest read/write speed. So if you have a device in which speed may play a crucial role, make sure you buy a higher "class" SDHC card. Please note that this SDHC card no longer has the fastest read/write speed available. There is now a new class, called "Class 10". Class 6 has a minimum read/write speed of 6MB/sec... while Class 2 has minimum speed rating of 2MB/sec, and Class 4 is 4MB/sec. Starting to see the pattern?


SO WHAT'S THE DIFFERENCE BETWEEN "SD CARDS" AND "SDHC CARDS?

SDHC is basically an upgrade to the older SD cards. The reason they upgraded it was to achieve greater data transfer speeds AND capacity than previously possible with normal SD cards... and to do this, they had to redesign the card (which is why it's not compatible with normal SD devices). This was necessary because digital cameras and digital video cameras these days have higher resolutions, which equate to larger file sizes and faster data transfer needs.

Now that many digital cameras also can record HD video, you may consider getting a larger capacity card because video takes much more space than photos. The size of the video varies from camera to camera depending on what resolution and video compression the camera uses. If you plan on taking lots of video (especially HD video), I would consider getting at least a 16GB card. Check your camera specifications to see how many minutes per Gig of memory your camera can capture ...to gauge how big of a memory card you'll want to get to meet your needs.

Special Note on regular SD Cards:
If you primarily take casual photos and don't need a exceptionally fast read/write capable card, you should know that newer cameras that take "SDHC" cards will also work with older normal "SD" cards. These older cards are cheaper than the new SDHC cards, so this may be something to consider. So to sum things up, newer cameras will take SDHC and regular SD cards, but older cameras that use SD cards may not be able to use SDHC cards. This is because newer technology is usually made to be compatible with older technology (the technical term used to describe this is "backwards compatibility") ... but older technology may not have the hardware necessary to run newer tech (technical term used is "obsolete"... just kidding! ;)

I hope I haven't confused everybody by going into this much detail, but I can't help being the nerd that I am. If you are confused, don't hesitate to comment on this post and I will try my best to answer your questions. Also, any feedback is always welcome!

Conclusion: Buy the card if you have a new device that uses SDHC. It rocks! (This message has been approved by the "Duke of New Mexico")

Transcend 4 GB Class 6 SDHC Card - Good Card for SDHC Compatible Devices, May 10, 2008
UPDATE - March 2, 2010: This review was originally written for the 4 GB class 6 SDHC card, but the reviews have been grouped for all class 6 SDHC cards in the 4, 8, 16 and 32 GB sizes. All the cards should perform similarly since they are all class 6 and all made by Transcend. However, I will have to check which cards I have used hands on. I believe I only own the 4GB and 8GB cards. I will update the review further. If you have concerns regarding the 16GB or 32GB sizes, you should seek out the reviews tagged with the product links from those cards.


The Transcend 4GB SDHC CARD (Class 6) is a great card for the price. I was at first a little skeptical about the brand, but I buy way too many memory cards to ignore a good price when I see one. And I'm happy to report that I've experienced decent performance and reliability issues with this card. That's as compared to other cards I own including SanDisk, PNY and Kingston.

As long as your devices are compatible with the SDHC format, this card is a good buy. 4 GB is a nice size though I do prefer 8 GB capacity for high capacity storage.

The class 6 speed is the fastest speed available in mass market SDHC cards. Class 6 guarantees minimum transfer speeds of 6 MBs, but I've gotten speeds up to 20Mbs! That makes this card perfect for storing pictures in RAW image formats.

The Class 6 speed is on par with the Sandisk Extreme III cards that on average are about $15 to $20 more per card. If you don't have an SDHC reader, you may opt to get the package with a reader included to download your pics. If not you can just transfer your pics directly from your camera with your card still inserted. An SDHC card reader can be bought separately if your PC doesn't have a compatible slot.

General SDHC and SD Card Tips

There are a few tips that I've learned the hard way through buying TOO MANY different memory cards.
1. Make sure your device is compatible with the card! Even in regular SD cards, some older electronics aren't compatible with that large of a size (2 GB). In terms of SDHC cards, make sure your camera or other device is SDHC compatible. SDHC is different from regular SD and only newer devices tend to have built-in compatibility
2. Once you install this in your camera or device, you will generally want to format the card with your compatible device's interface. That is because the standard formats for certain devices, particularly Canon, are different from the factory installed format
3. Just like your devices, most computer SD card readers are not compatible with the SDHC format. So use a card reader or download the pictures via USB connection to the camera with the card still installed.
4. For some reason, placing the card in the locked position allows some older laptops to still read it. This is just to be used in a pinch however, and it won't apply to all systems
5. If you did not properly format your card, you may be able to save things to it and then have them "disappear." If this happens to you, make sure you use the software recovery tools BEFORE you try to save anything else to your card. That way, you can retrieve your images without over-writing them.
6. Make sure you know what you are going to use this card for. Once you have set up everything and ensured it's all compatible, you still have to decide on speed. If you are using this for storing RAW images instead of JPEGs or HD video, step up to the faster class 6 speed format if you can afford it.
7. If you are going to pay more for a faster speed, make sure your device can benefit from it. I've read, for example, that Kodak cameras are set to a fixed voltage and cannot go faster than standard speed. So the extra cash spent on Class 4, 5, or 6 is basically wasted.

Conclusion

It's great to have several extra cards on hand just in case. This 4 GB card is a nice performer. If you have a high capacity camera (10 Megapixels or more) and are storing videos or RAW images, the extra cash for the 8GB card is worth it. Or you may want to step up to the larger 16 GB size that is now available.

Enjoy!

Transcend 32 GB SDHC Review, May 25, 2009
Before you drop 120~$ for a SD card ask yourself, Do you really need 32GB card? because the card itself with same specs costs only 35$ for the 16GB version, anyway here is info that might help you

Pros :
1- Class 6 Card the(guaranteed minimum Read/write speed of 6MB/s)
2- My Test Results 18.2-18.5MB/S Read - 11.6-11.8 Write (very stable)
3- Faster than average cards and almost close to top speed SDHC cards
4- 32GB in a single small chip is awesome(You can use it as a portable HD once in a while, i share some stuff with my friends with it sometimes


Cons :
1- Expensive
2- You can get two 16GB cards for around only 70$ and save yourself 50$~
3- Slow write speeds for a 32GB card (Takes forever to fill it with DATA from PC, its not the card fault though , its just the SDHC technology is getting old and slow for 2009 standards , time for newer Tech)

* Important Info

Avoid the Sandisk Ultra Series they never reach the true marketed speed "15MB-20MB/S" its just in theory speed like how everybody knows that USB2 is much slower than its specs, and they are only Class 2 for the 32GB version which will drop frames from your HD video (Plus Class 4 is minimum requirement for shooting in HD ) if you plan to get San disk Card then get the Extreme III Series (but again from my own Tests there read speed is about 20MB not 30MB and the write speed is 14MB/s~ instead of the transcend 11MB/s write speed (Unless you spam shooting pictures with your DSLR you don't "need" faster speed)

I bought This card because i plan to take videos with my HD camcorder that last more 2 Hours, if you do not plan to shoot for longtime then you are better with getting the 16GB card HOWEVER, if you are lazy like my mom and do not plan to transfer DATA from the card to Your computer HD after every trip, then get the 32GB card.or you gonna end up on a trip and a message pops "No memory"

If you plan to shoot for longer time, check your camcorder battery too does it even last that long? so be sure about that before you drop over 100$ for this card

product failed., July 26, 2009
Well, it was great while it lasted. Unfortunately, it did not last long.

Like other reviewers, after <20 use cycles the device failed and I got a "lock" error when, in fact, the write-protection lock was not engaged. Oddly, by engaging the lock (i.e. entering read-only mode) I was able to remove the picture files from the card. Obviously, further use in the camera was impossible; I was also unable to reformat the card (either with my camera or with the SD Associations free software [..]).

This card has a high average rating but I would urge customers to consider the number of 1-star ratings due to complete product failure before they purchase this item.

My Canon loves the 8 GB SDHC card, January 15, 2008
I recently purchased a Canon Powershot A720IS digital camera that is capable of recognizing and using up to 2 TERRABYTES of memory card (in the future) so I wanted to get the largest memory card I could install for now. I wanted to use the camera both on dry land and with an underwater housing for shooting stills and video on dive trips. Camera specs said an 8 GB SDHC card would record one hour of hi res video at 30 fps. Or nearly 2300 hi res stills at 8 megapixels.

A test of the Transcend 8GB SDHC card in the camera ended up shooting 70 minutes of full screen, 30fps digital video that could not be distinguished from my DV camcorder video quality. Playback from the memory card to the TV was so fast & efficient there was never a single "stutter" on the screen. The card speed is genuinely FAST as advertised. Low level formatting of the card allowed for very acceptable rapid-fire sequential still photo shooting speeds when light levels were bright enough that the flash was not needed/used. Something like 2 photos every 3 seconds. Files were flawless in display, both for stills and video.

This product was significantly lower in price than the Kingston 8GB SDHC card I originally bought with the camera. I've used both interchangeably and cannot see any different in the speed or capacity and quality of imagery is identical. For the money I'll stick with Transcend and am looking forward to getting their 16GB card once the price drops substantially below the $100 mark. That would provide nearly 2 1/2 hours of video on my still camera or 4600 highest quality stills. I'm afraid my camcorder will be collecting dust much of the time. A big advantage to video on the card is there are NO MOVING PARTS, e.g. a mini DV tape cassette and camcorder or VCR playback unit needed to dump the video and stills to my Mac for editing and burning DVDs. I just stick the card in the MicroMate USB card reader, plug it in the computer and bingo, ready to sort thru and dump to the hard drive. Since the card is formatted by a Canon camera it automatically boots up the Canon Viewer software too. That should work the same for other brands of still cameras formatting this chip.

The Fastest Card at This Price But..., June 26, 2007
This SDHC card is the fastest one in its price range but it may cause your images to be lost.

I use two of this in a Canon SD750. After the first use, all of the images were lost. (But thank God, I could rescue them with Lexar Image Rescue 2, a program better than its competitors) Then I formated the card(s) in the camera(s) with "low level format" option several times and there has been no problem after that so far.

I can suggest these points to potential owners of this card:
1- Use it very carefully, make backups if possible.
2- Format it several times before the first use with "low level format" option.
3- If you loose your images, don't panic. At this situation, It is very important not to take anymore pictures. If you take pictures after this point, you can overwrite your lost images and there can be no chance to get them back. Connect your card to your computer with a card reader (SDHC Compatible) and rescue them with Lexar Image Rescue.

Excellent Mini Hard Drive equivalent, December 11, 2007
This card is able to hold a complete DVD movie, thousands of songs/photos, or just serve as a backup device for one's files.

It operates very well - I now have purchased 3 and with each use its value becomes more apparent.

One word of caution - even though most laptops and systems have an SD card slot, older computers may not be able to recognize or write to this card. Make sure your system has the ability to read SDHC configured products.

If you do not have an SD slot you can purchase an tiny SD reader (very inexpensive) that plugs into your USB port.

Great value, just be careful..., January 2, 2009
I recently ordered this card as an accessory for my Acer Aspire One netbook PC. The card took a little while to ship, about 8 days, but that wasn't a big deal. The card has lots of space, and the read speeds are quite impressive. I mostly use it to run and store portable software, and it does a very good job at that.

My only complaint is that when I first inserted the card into my PC it attempted to install some adware. The program was from a company called RelevantKnowledge, and they gather your information for market research purposes. Luckily my spyware software picked it up immediately,so I was able to delete it. Afterward I formatted the card, and now I'm happy as can be.

Reliable card, good speeds!, December 4, 2008
Transcend 16 GB SDHC SD Class 6 Flash Memory Card TS16GSDHC6E [Amazon Frustration-Free Packaging]
I have 4 of these cards that I use in my Panasonic HMC-150, a professional grade video camera. I've run read/write tests on all of them and they get about 14 MB/s write speeds and 17.5 MB/s read speeds. Never encountered any errors! These cards are the best bang for your buck, and the frustration free packaging is awesome.

Don't Let This Happen to You....., August 3, 2008
It's great to have 8GB of memory but it is a double edged sword. Today after using this card for only the second time, it failed on me. I lost almost 200 precious images - gone forever. I am what you would call an enthusiast or hobbyist. I love photography and spend every spare minute, which is very seldom these days, pursuing my passion. So I do a fair amount of experimentation. These cards are great when they work - but if they fail you even once - the results can be catastrophic. Maybe I am the unlucky 1 of 250 reviewers with a bad experience with this product, but I feel it is my responsibility to report this to everyone. I hope it never happens to you. It is human nature for me to wonder, if I had spent a few more dollars for a better brand name, would my photos be intact today?

2- My Test Results 18.2-18.5MB/S Read - 11.6-11.8 Write (very stable)
3- Faster than average cards and almost close to top speed SDHC cards
4- 32GB in a single small chip is awesome(You can use it as a portable HD once in a while, i share some stuff with my friends with it sometimes


Cons :
1- Expensive
2- You can get two 16GB cards for around only 70$ and save yourself 50$~
3- Slow write speeds for a 32GB card (Takes forever to fill it with DATA from PC, its not the card fault though , its just the SDHC technology is getting old and slow for 2009 standards , time for newer Tech)

* Important Info

Avoid the Sandisk Ultra Series they never reach the true marketed speed "15MB-20MB/S" its just in theory speed like how everybody knows that USB2 is much slower than its specs, and they are only Class 2 for the 32GB version which will drop frames from your HD video (Plus Class 4 is minimum requirement for shooting in HD ) if you plan to get San disk Card then get the Extreme III Series (but again from my own Tests there read speed is about 20MB not 30MB and the write speed is 14MB/s~ instead of the transcend 11MB/s write speed (Unless you spam shooting pictures with your DSLR you don't "need" faster speed)

I bought This card because i plan to take videos with my HD camcorder that last more 2 Hours, if you do not plan to shoot for longtime then you are better with getting the 16GB card HOWEVER, if you are lazy like my mom and do not plan to transfer DATA from the card to Your computer HD after every trip, then get the 32GB card.or you gonna end up on a trip and a message pops "No memory"

If you plan to shoot for longer time, check your camcorder battery too does it even last that long? so be sure about that before you drop over 100$ for this card

product failed., July 26, 2009
Well, it was great while it lasted. Unfortunately, it did not last long.

Like other reviewers, after <20 use cycles the device failed and I got a "lock" error when, in fact, the write-protection lock was not engaged. Oddly, by engaging the lock (i.e. entering read-only mode) I was able to remove the picture files from the card. Obviously, further use in the camera was impossible; I was also unable to reformat the card (either with my camera or with the SD Associations free software [..]).

This card has a high average rating but I would urge customers to consider the number of 1-star ratings due to complete product failure before they purchase this item.

My Canon loves the 8 GB SDHC card, January 15, 2008
I recently purchased a Canon Powershot A720IS digital camera that is capable of recognizing and using up to 2 TERRABYTES of memory card (in the future) so I wanted to get the largest memory card I could install for now. I wanted to use the camera both on dry land and with an underwater housing for shooting stills and video on dive trips. Camera specs said an 8 GB SDHC card would record one hour of hi res video at 30 fps. Or nearly 2300 hi res stills at 8 megapixels.

A test of the Transcend 8GB SDHC card in the camera ended up shooting 70 minutes of full screen, 30fps digital video that could not be distinguished from my DV camcorder video quality. Playback from the memory card to the TV was so fast & efficient there was never a single "stutter" on the screen. The card speed is genuinely FAST as advertised. Low level formatting of the card allowed for very acceptable rapid-fire sequential still photo shooting speeds when light levels were bright enough that the flash was not needed/used. Something like 2 photos every 3 seconds. Files were flawless in display, both for stills and video.

This product was significantly lower in price than the Kingston 8GB SDHC card I originally bought with the camera. I've used both interchangeably and cannot see any different in the speed or capacity and quality of imagery is identical. For the money I'll stick with Transcend and am looking forward to getting their 16GB card once the price drops substantially below the $100 mark. That would provide nearly 2 1/2 hours of video on my still camera or 4600 highest quality stills. I'm afraid my camcorder will be collecting dust much of the time. A big advantage to video on the card is there are NO MOVING PARTS, e.g. a mini DV tape cassette and camcorder or VCR playback unit needed to dump the video and stills to my Mac for editing and burning DVDs. I just stick the card in the MicroMate USB card reader, plug it in the computer and bingo, ready to sort thru and dump to the hard drive. Since the card is formatted by a Canon camera it automatically boots up the Canon Viewer software too. That should work the same for other brands of still cameras formatting this chip.

The Fastest Card at This Price But..., June 26, 2007
This SDHC card is the fastest one in its price range but it may cause your images to be lost.

I use two of this in a Canon SD750. After the first use, all of the images were lost. (But thank God, I could rescue them with Lexar Image Rescue 2, a program better than its competitors) Then I formated the card(s) in the camera(s) with "low level format" option several times and there has been no problem after that so far.

I can suggest these points to potential owners of this card:
1- Use it very carefully, make backups if possible.
2- Format it several times before the first use with "low level format" option.
3- If you loose your images, don't panic. At this situation, It is very important not to take anymore pictures. If you take pictures after this point, you can overwrite your lost images and there can be no chance to get them back. Connect your card to your computer with a card reader (SDHC Compatible) and rescue them with Lexar Image Rescue.

Excellent Mini Hard Drive equivalent, December 11, 2007
This card is able to hold a complete DVD movie, thousands of songs/photos, or just serve as a backup device for one's files.

It operates very well - I now have purchased 3 and with each use its value becomes more apparent.

One word of caution - even though most laptops and systems have an SD card slot, older computers may not be able to recognize or write to this card. Make sure your system has the ability to read SDHC configured products.

If you do not have an SD slot you can purchase an tiny SD reader (very inexpensive) that plugs into your USB port.

Great value, just be careful..., January 2, 2009
I recently ordered this card as an accessory for my Acer Aspire One netbook PC. The card took a little while to ship, about 8 days, but that wasn't a big deal. The card has lots of space, and the read speeds are quite impressive. I mostly use it to run and store portable software, and it does a very good job at that.

My only complaint is that when I first inserted the card into my PC it attempted to install some adware. The program was from a company called RelevantKnowledge, and they gather your information for market research purposes. Luckily my spyware software picked it up immediately,so I was able to delete it. Afterward I formatted the card, and now I'm happy as can be.

Reliable card, good speeds!, December 4, 2008
Transcend 16 GB SDHC SD Class 6 Flash Memory Card TS16GSDHC6E [Amazon Frustration-Free Packaging]
I have 4 of these cards that I use in my Panasonic HMC-150, a professional grade video camera. I've run read/write tests on all of them and they get about 14 MB/s write speeds and 17.5 MB/s read speeds. Never encountered any errors! These cards are the best bang for your buck, and the frustration free packaging is awesome.

Don't Let This Happen to You....., August 3, 2008
It's great to have 8GB of memory but it is a double edged sword. Today after using this card for only the second time, it failed on me. I lost almost 200 precious images - gone forever. I am what you would call an enthusiast or hobbyist. I love photography and spend every spare minute, which is very seldom these days, pursuing my passion. So I do a fair amount of experimentation. These cards are great when they work - but if they fail you even once - the results can be catastrophic. Maybe I am the unlucky 1 of 250 reviewers with a bad experience with this product, but I feel it is my responsibility to report this to everyone. I hope it never happens to you. It is human nature for me to wonder, if I had spent a few more dollars for a better brand name, would my photos be intact today? ... Read more

Great affordable SDHC card, March 28, 2008
UPDATE - March 2, 2010: This review was originally written for the 4 GB class 6 SDHC card, but the reviews have been grouped for all class 6 SDHC cards in the 4, 8, 16 and 32 GB sizes. All the cards should perform similarly since they are all class 6 and all made by Transcend. However, I will have to check which cards I have used hands on. I believe I only own the 4GB and 8GB cards. I will update the review further. If you have concerns regarding the 16GB or 32GB sizes, you should seek out the reviews tagged with the product links from those cards.


The Transcend 4GB SDHC CARD (Class 6) is a great card for the price. I was at first a little skeptical about the brand, but I buy way too many memory cards to ignore a good price when I see one. And I'm happy to report that I've experienced decent performance and reliability issues with this card. That's as compared to other cards I own including SanDisk, PNY and Kingston.

As long as your devices are compatible with the SDHC format, this card is a good buy. 4 GB is a nice size though I do prefer 8 GB capacity for high capacity storage.

The class 6 speed is the fastest speed available in mass market SDHC cards. Class 6 guarantees minimum transfer speeds of 6 MBs, but I've gotten speeds up to 20Mbs! That makes this card perfect for storing pictures in RAW image formats.

The Class 6 speed is on par with the Sandisk Extreme III cards that on average are about $15 to $20 more per card. If you don't have an SDHC reader, you may opt to get the package with a reader included to download your pics. If not you can just transfer your pics directly from your camera with your card still inserted. An SDHC card reader can be bought separately if your PC doesn't have a compatible slot.

General SDHC and SD Card Tips

There are a few tips that I've learned the hard way through buying TOO MANY different memory cards.
1. Make sure your device is compatible with the card! Even in regular SD cards, some older electronics aren't compatible with that large of a size (2 GB). In terms of SDHC cards, make sure your camera or other device is SDHC compatible. SDHC is different from regular SD and only newer devices tend to have built-in compatibility
2. Once you install this in your camera or device, you will generally want to format the card with your compatible device's interface. That is because the standard formats for certain devices, particularly Canon, are different from the factory installed format
3. Just like your devices, most computer SD card readers are not compatible with the SDHC format. So use a card reader or download the pictures via USB connection to the camera with the card still installed.
4. For some reason, placing the card in the locked position allows some older laptops to still read it. This is just to be used in a pinch however, and it won't apply to all systems
5. If you did not properly format your card, you may be able to save things to it and then have them "disappear." If this happens to you, make sure you use the software recovery tools BEFORE you try to save anything else to your card. That way, you can retrieve your images without over-writing them.
6. Make sure you know what you are going to use this card for. Once you have set up everything and ensured it's all compatible, you still have to decide on speed. If you are using this for storing RAW images instead of JPEGs or HD video, step up to the faster class 6 speed format if you can afford it.
7. If you are going to pay more for a faster speed, make sure your device can benefit from it. I've read, for example, that Kodak cameras are set to a fixed voltage and cannot go faster than standard speed. So the extra cash spent on Class 4, 5, or 6 is basically wasted.

Conclusion

It's great to have several extra cards on hand just in case. This 4 GB card is a nice performer. If you have a high capacity camera (10 Megapixels or more) and are storing videos or RAW images, the extra cash for the 8GB card is worth it. Or you may want to step up to the larger 16 GB size that is now available.

Enjoy!

Transcend 32 GB SDHC Review, May 25, 2009
Before you drop 120~$ for a SD card ask yourself, Do you really need 32GB card? because the card itself with same specs costs only 35$ for the 16GB version, anyway here is info that might help you

Pros :

Transcend 16 GB SDHC SD Class 6 Flash Memory Card TS16GSDHC6E [Amazon Frustration-Free Packaging]

Great affordable SDHC card, March 28, 2008
In the past, I bought a Transcend 8GB SDHC card for my Canon SD1000 camera. I recently bought the Transcend 16GB SDHC for my new Canon SX20IS. Both cards work very well and I've had no problems with it so far. I wanted to take this opportunity to update my review since my original review was also posted (by Amazon) for the 16GB card. This is because the only difference between these two cards is the different capacity. So, if you're in the market for an affordable high quality SDHC card, this may be the one for you. Sorry, I kind of sounded like a used car salesman right there, didn't I? I assure you that I don't work for Transcend. But, here's why I think this card is awesome:

Pros:

-Affordable!

-Large capacity

-Class 6 read/write speed (which is very fast... but is no longer the fastest class available)

-Lifetime warranty (at least that's what the package says :)

-Transcend is a reputable company that's been making memory products for a very long time. ( I swear to the tech Gods that I don't work for them!) Other reputable and reliable memory card companies include Kingston and PNY. All three of these companies have been making memory chips for many, many years.


Cons:

- I can' really think of any "Cons" about this card. But here's the 2 closest things I can come up with right now: (1) "Class 6" is no longer the fastest speed available and (2) This card does NOT make coffee for you in the morning, do your dishes for you, give you compliments when you're having a bad day, or magically improve your photography skills.




IMPORTANT SPECIAL NOTES ABOUT SDHC MEMORY CARDS:

-SDHC cards are not compatible with most older SD cameras, SD devices, or SD card readers.

-SDHC cards are rated by speed using different "classes". There are currently 4 data transfer speed classes available for SDHC cards. These classes are "class 2, class 4, and class 6, and the new class 10. For example, "Class 2" would have the slowest read/write speed while "Class 6" has the fastest read/write speed. So if you have a device in which speed may play a crucial role, make sure you buy a higher "class" SDHC card. Please note that this SDHC card no longer has the fastest read/write speed available. There is now a new class, called "Class 10". Class 6 has a minimum read/write speed of 6MB/sec... while Class 2 has minimum speed rating of 2MB/sec, and Class 4 is 4MB/sec. Starting to see the pattern?


SO WHAT'S THE DIFFERENCE BETWEEN "SD CARDS" AND "SDHC CARDS?

SDHC is basically an upgrade to the older SD cards. The reason they upgraded it was to achieve greater data transfer speeds AND capacity than previously possible with normal SD cards... and to do this, they had to redesign the card (which is why it's not compatible with normal SD devices). This was necessary because digital cameras and digital video cameras these days have higher resolutions, which equate to larger file sizes and faster data transfer needs.

Now that many digital cameras also can record HD video, you may consider getting a larger capacity card because video takes much more space than photos. The size of the video varies from camera to camera depending on what resolution and video compression the camera uses. If you plan on taking lots of video (especially HD video), I would consider getting at least a 16GB card. Check your camera specifications to see how many minutes per Gig of memory your camera can capture ...to gauge how big of a memory card you'll want to get to meet your needs.

Special Note on regular SD Cards:
If you primarily take casual photos and don't need a exceptionally fast read/write capable card, you should know that newer cameras that take "SDHC" cards will also work with older normal "SD" cards. These older cards are cheaper than the new SDHC cards, so this may be something to consider. So to sum things up, newer cameras will take SDHC and regular SD cards, but older cameras that use SD cards may not be able to use SDHC cards. This is because newer technology is usually made to be compatible with older technology (the technical term used to describe this is "backwards compatibility") ... but older technology may not have the hardware necessary to run newer tech (technical term used is "obsolete"... just kidding! ;)

I hope I haven't confused everybody by going into this much detail, but I can't help being the nerd that I am. If you are confused, don't hesitate to comment on this post and I will try my best to answer your questions. Also, any feedback is always welcome!

Conclusion: Buy the card if you have a new device that uses SDHC. It rocks! (This message has been approved by the "Duke of New Mexico")

My Canon loves the 8 GB SDHC card, January 15, 2008
I recently purchased a Canon Powershot A720IS digital camera that is capable of recognizing and using up to 2 TERRABYTES of memory card (in the future) so I wanted to get the largest memory card I could install for now. I wanted to use the camera both on dry land and with an underwater housing for shooting stills and video on dive trips. Camera specs said an 8 GB SDHC card would record one hour of hi res video at 30 fps. Or nearly 2300 hi res stills at 8 megapixels.

A test of the Transcend 8GB SDHC card in the camera ended up shooting 70 minutes of full screen, 30fps digital video that could not be distinguished from my DV camcorder video quality. Playback from the memory card to the TV was so fast & efficient there was never a single "stutter" on the screen. The card speed is genuinely FAST as advertised. Low level formatting of the card allowed for very acceptable rapid-fire sequential still photo shooting speeds when light levels were bright enough that the flash was not needed/used. Something like 2 photos every 3 seconds. Files were flawless in display, both for stills and video.

This product was significantly lower in price than the Kingston 8GB SDHC card I originally bought with the camera. I've used both interchangeably and cannot see any different in the speed or capacity and quality of imagery is identical. For the money I'll stick with Transcend and am looking forward to getting their 16GB card once the price drops substantially below the $100 mark. That would provide nearly 2 1/2 hours of video on my still camera or 4600 highest quality stills. I'm afraid my camcorder will be collecting dust much of the time. A big advantage to video on the card is there are NO MOVING PARTS, e.g. a mini DV tape cassette and camcorder or VCR playback unit needed to dump the video and stills to my Mac for editing and burning DVDs. I just stick the card in the MicroMate USB card reader, plug it in the computer and bingo, ready to sort thru and dump to the hard drive. Since the card is formatted by a Canon camera it automatically boots up the Canon Viewer software too. That should work the same for other brands of still cameras formatting this chip.

The Fastest Card at This Price But..., June 26, 2007
This SDHC card is the fastest one in its price range but it may cause your images to be lost.

I use two of this in a Canon SD750. After the first use, all of the images were lost. (But thank God, I could rescue them with Lexar Image Rescue 2, a program better than its competitors) Then I formated the card(s) in the camera(s) with "low level format" option several times and there has been no problem after that so far.

I can suggest these points to potential owners of this card:
1- Use it very carefully, make backups if possible.
2- Format it several times before the first use with "low level format" option.
3- If you loose your images, don't panic. At this situation, It is very important not to take anymore pictures. If you take pictures after this point, you can overwrite your lost images and there can be no chance to get them back. Connect your card to your computer with a card reader (SDHC Compatible) and rescue them with Lexar Image Rescue.

Excellent Mini Hard Drive equivalent, December 11, 2007
This card is able to hold a complete DVD movie, thousands of songs/photos, or just serve as a backup device for one's files.

It operates very well - I now have purchased 3 and with each use its value becomes more apparent.

One word of caution - even though most laptops and systems have an SD card slot, older computers may not be able to recognize or write to this card. Make sure your system has the ability to read SDHC configured products.

If you do not have an SD slot you can purchase an tiny SD reader (very inexpensive) that plugs into your USB port.

Great value, just be careful..., January 2, 2009
I recently ordered this card as an accessory for my Acer Aspire One netbook PC. The card took a little while to ship, about 8 days, but that wasn't a big deal. The card has lots of space, and the read speeds are quite impressive. I mostly use it to run and store portable software, and it does a very good job at that.

My only complaint is that when I first inserted the card into my PC it attempted to install some adware. The program was from a company called RelevantKnowledge, and they gather your information for market research purposes. Luckily my spyware software picked it up immediately,so I was able to delete it. Afterward I formatted the card, and now I'm happy as can be.

Reliable card, good speeds!, December 4, 2008
Transcend 16 GB SDHC SD Class 6 Flash Memory Card TS16GSDHC6E [Amazon Frustration-Free Packaging]
I have 4 of these cards that I use in my Panasonic HMC-150, a professional grade video camera. I've run read/write tests on all of them and they get about 14 MB/s write speeds and 17.5 MB/s read speeds. Never encountered any errors! These cards are the best bang for your buck, and the frustration free packaging is awesome.

Don't Let This Happen to You....., August 3, 2008
It's great to have 8GB of memory but it is a double edged sword. Today after using this card for only the second time, it failed on me. I lost almost 200 precious images - gone forever. I am what you would call an enthusiast or hobbyist. I love photography and spend every spare minute, which is very seldom these days, pursuing my passion. So I do a fair amount of experimentation. These cards are great when they work - but if they fail you even once - the results can be catastrophic. Maybe I am the unlucky 1 of 250 reviewers with a bad experience with this product, but I feel it is my responsibility to report this to everyone. I hope it never happens to you. It is human nature for me to wonder, if I had spent a few more dollars for a better brand name, would my photos be intact today? ... Read more

Nice snug fit for Canon S90, October 14, 2009
This little case is the perfect size for my new Polaroid digital camera. It has a handy little zippered pocket big enough to store an extra battery and/or SD cards. It also came with a 'caribiner' type belt clip. Plus, I like that it's orange, just like my camera. The price is right too!

Nice snug fit for Canon S90, October 14, 2009
I tried several cases for my new Canon S90 and this case had the best snug fit for the S90 without being too snug. It will provide a modest level of protection for the camera without adding unnecessary bulk. The outer pocket will hold an extra battery and/or memory card.

It saved my camera, December 22, 2009
I recently purchased a Canon S90 to complement my 5DmkII on a safari in Tanzania. Throughout the trip I had the S90 on my belt for quick and easy access; the case isn't bulky and seemed to protect the camera well enough from the occasional knock as the land cruiser hit big bumps.

On my last day in Tanzania I was walking through the streets of Arusha when suddenly I felt a hard tug that almost spun me around. I turned to see a man starting to flee. I started off in pursuit--concerned more about the memory card than the camera itself--but after a few steps realized the camera was still at my side, only a slight rip in the strap indicating anything had happened.

Recommended as a sturdy carrying case with a reasonable amount of padding for impact protection (you won't want to drop it from very high or expose it to strong blows).

Nice generic, cheap case for the S90, January 14, 2010
This case happens to be a good fit for the Canon S90. If you're hiking or are on vacation, it'll get you that crucial amount of padding plus room for 1 or 2 spare batteries and SD card. I particularly like the fact that the belt loop is fixed (not a clip), so once you put it on, you can be confident that it stays on, no matter which woods you're cutting your way through. Use a wider belt if you have one, the case wiggles a little with slim belts.

If you're out in Metropolis though, the "outdoor factor" may be just a tad over the edge. You can remove the metal hook and cut off the bright label with sharp scissors, but it'll still look a bit too dorky for, say, the opera or sushi gathering. For such occasions, you'll do better with Canon's PSC900 Deluxe Leather Case.

Snug fit for DMC-ZS7, June 26, 2010
I read this was a good case to get for the Panasonic Lumix DMC-ZS7 so I ordered one at the same time I ordered my camera.

I got them on the same day and was happy.

I like the case, it is padded and has a little pocket in the front, but I was hoping the pocket was a little bigger. You can't really fit anything in there.. maybe a SD card, but it can't have to bulky a case and there is no way a battery will fit in there.

As for the camera, I liked it at first, it has a snug fit and seemed perfect, but then I realized how unperfect it was. I put the wrist band on it and all the sudden it was way to hard to close, I was afraid I'd scratch it trying to get it zipped. I found a way around this by turning the camera backwards facing away from the pocket.

Another thing I noticed and I HATED was when it was turned the right way with the wrist band on (not sure about without it.. only noticed after I put it on) is that the fit was TO tight that sometimes when zipping it up the zipper hits the on off switch and tries to turn it on.. which isn't good cuz the lense has no where to go! Again, turning it backwards seems to help with this, but I still have to be real careful when putting it up to avoid hitting it...

I like the snug fit but at the same time I wish it was a little bit bigger, I'm afraid if I am in to big of a hurry I might accidently hit the camera with the zipper or something.

Perfect for a Canon S95, November 3, 2010
This case has the perfect fit for a Canon S95, and the outer pocket holds a spare battery and memory card. The belt loop and carabiner are both secure.

Perfect fit in my pocket (For a Canon SD4000), July 15, 2010
I just purchased a Canon SD4000 and wanted a good case to secure the camera. I went with Caselogic TBC-302 and I love the fit.
I had many different cases and every time I get frustrated of keeping the camera in the case because it doesn't fit in my pocket.
Usually, I would just keep the case in my bag and the camera in my pocket.

The TBC-302 size fits comfortably in a regular pair of jeans.
Enough room for a spare battery and SD card.

Perfect size for my Polaroid Digital Camera, May 14, 2010

Perfect little case, July 19, 2010
I bought this case to replace my old CaseLogic case because it didn't have a spare pocket to hold small accessories. This case is small and light enough so that I can carry it around all day without noticing it that much, but it is has enough room and padding so that it carries my camera (Panasonic FH20), a spare battery, and a SD card and it protects my camera if I drop it.

I would recommend this case to anyone looking for the perfect travel case for their ultra compact camera.

Good case for Lumix, July 9, 2010
Purchased this on advise from other reviews for the Panasonic Lumix ZS7 I purchased. Case holds the camera and an extra battery in the main section, and the memory chips in the small section. Has a loop to be attached to your belt. It is very small and a tight fit for the above, but it is perfect for what I wanted. Sturdy construction and has a little bit of padding to keep the camera secure. Perfect case for this camera and the few esstentials you need to bring along.

Beware, March 8, 2008
This is a must for loading music to listen to on my Palm TX. But BEWARE of eek Technoligies and buying at this price. They wanted $13.20 for shipping a 2 oz memory card? Buy from someone else even if it is a few dollars more and pay reasonable shipping rates. Don't be fooled by their cheap price they make it up 2x in shippoing charges. When I saw it I cancelled my order..

Make sure you can read it., December 24, 2007
Standard SD and SDHC cards look identical in size and shape, only SDHC-compatible products will be able to accept the new SDHC cards. SanDisk differentiates its new cards with the new SDHC logo on the card and retail package.

Now my web research finds that at the time of its release Wes Brewer, vice president of consumer product marketing at SanDisk, said, "In order to provide the easiest and most compatible solution for 4GB and larger capacity SDHC cards in the market, SanDisk chose to bundle its new MicroMate USB 2.0 SD/SDHC compatible card reader, which normally retails for $19.99, with this new card."

Note this deal does not include a reader.

In my case the device I bought it for can read it. Without the dedicated reader my year old HP computer cannot .

expensive SHIPPING!, March 23, 2008
I played around with the prices on this and found out several things. If I order this item, $11 in shipping costs is added by the third party supplier! If I get the 2G version, even two of them, those qualify for free shipping from Amazon and come out much cheaper. So check your prices on these before ordering. My hunch is that you can probably pick this 4G up cheaper at your local electronics/computer store...

Beware! does not work in many cameras, September 5, 2008
Finding that this product does not work in my one year old Canon camera I contacted the company and was given a list of cameras which do support it. This list belongs on the product description at the Amazon site. Besides the nuisance, I'll be out the $4.50 shipping cost for shipping an item requiring .59 cents postage.

Worked fine until it didn't work, December 15, 2008
I purchased this card five months ago and used it without incident. I was happy with the amount of space on the card. Suddenly today, for no apparent reason, a message came up saying "memory card error". I cannot access the photos on my card with my external card reader. I cannot use the card in my camera. The photos on the card are lost, and that makes me quite sad.

NOT compatible with Canon Powershot 590IS, September 9, 2008
The Sandisk site says this disk is compatible, and the user manual for the Canon Powershot 590IS says the camera can use SD or SDHC memory cards, so I assumed this card would be compatible. It wasn't. The camera says "memory card locked!" even when the card is unlocked. I'm giving this a one star rating because everything I looked at says this card is compatible, but it wasn't. For the Sandisk compatiblity site (which, of course, recommends their most expensive 32 and 16G cards first), see http://www.sandisk.com/Compatibility/Device(8725)-Canon-PowerShot_A590_IS.aspx . I haven't found a site so far that specifically recommends one card over another for this model of camera.

Love it!, May 6, 2008
I love it, it works as promised, and holds well over 30 minutes of video. Pops in and out of camera easily. It's a great product and worth the extra money over the 2.0 GB one.

Two thumbs up!

Works fine, October 29, 2007
Bought for a new camera and works fine. Many older SD card units won't handle 4GB and larger cards so make sure that yours will. If you are buying this for a PC there are USB adapters for these larger cards.

Great, April 3, 2008
This is a great addition to a digital camera if you shoot video clips.
Just make sure that the digital camera supports SD cards over 2Gb. You can usually be confident it will work if the device is labeled SD HC compliant (SD HC is the 4-32Gb standard). It may work in other devices (my Kodak camera is not labeled for SD HC but the card works.)

Never been disappointed, March 26, 2008

4GB SDHC Class 4 Flash Card ... Read more

Reviews

Kingston quality, massive storage, what's not to love?, December 2, 2008
There are some things to consider before buying this particular card or any other 32gb SDHC card on the market:

1. This is NOT an ideal card for a digital SLR like a D80, D90, Rebel XT, etc... That is because it is a class 4 device. The class of a SDHC cards has to do with how fast they read and write files, not how much storage they have. For a digital SLR, you should purchase a class 6 SDHC card most of the time. Class 6 cards will allow you to take 'bursts' of photos and not be limited by the card's capacity to write them. Also class 4 cards are slower reading data, meaning they will take longer to upload files to your computer. Upload speed is convenient, especially when loading large batches of files.

2. This card has far more storage than most people will need for their digital camera. Unless you like to keep all your photos on a SDHC card and never move them to your computer, or are a high volume photographer, there is very little need for more than about 8gb of storage space for most caeras. The possible exception to this is if you have a professional SLR that shoots files in the 16-20mb range--but if you do, you'll likely want a class 6 card anyway. If all you intend to use this card for is a digital camera, save yourself a lot of money and buy a PNY 8GB SDHC Card. If you're worried about running out of space on a vacation, buy a few of them. Otherwise you run the risk of having 'all your eggs in one basket.' If one card fails, you lose all your pictures instead of only a portion of them.

This card is fantastic for use in a video camcorder capable of writing to an SDHC card. (Check with the manual first to insure that a class 4 card will be fast enough first). It is also perfect as extra storage for an ultra portable computer or net book like the Asus EEE pc. Another great application would be as added storage to a personal media player or MP3 player equipped with a SDHC slot such as the Cowon D2.

There are other good 32gb SDHC cards on the market, some at cheaper price points than the Kingston card. IMHO, brand matters very little with something like a SDHC card, since they all are made pretty much the same way. None of the brands currently offering them (Transcend, PNY, Kingston) have high fail rates with their other products, so I believe they are all pretty similar. What you decide to buy will depend on whether you trust a particular brand, or who has the lowest price. All of them will work equally well.

Very Big, September 8, 2008
PREFACE:

I bought this card for extra disk space on my Asus EeePC netbook. I needed as much space as possible to supplement the very small SSD hard drive. I needed something with large capacity and relatively fast file transfer time.

PROS:

It shares the largest SD capacity on the market today with few others (Panasonic, Sandisk, and PNY) and is a quality name that I have had a good history with in the past. Its file transfer time is similar to the SSD drive in my machine so it basically acts as a second SSD for me at less than a quarter of the price!

CONS:

Its not the cheapest 32gb SD card(PNY) nor the fastest(Panasonic) but its good quality with a decent transfer rate.

CONCLUSION:

I'm very happy with its performance and capacity. I would like to see the price come down a bit, but that's the price of getting electronics of this caliber.

That's my input, take it or leave it :)

Good for the money, but don't expect fast speeds., December 8, 2007
I didnt realize how fast the point and shoot cameras are getting sooo many megapixels until I started looking for a good one for my mom... This card is no good for a 12 megapixel camera! It takes way too long to save each picture slowing down how fast you're able to take consecutive pictures! Go for the Sandisk extreme cards and dont look back!

I only have SLR cameras, and use the San Disk extreme cards because speed is crucial! Dont cheap out on a card after buying a nice camera, or you'll be sorry! Thats the first thing i noticed when showing her how to use her new Canon Point and Shoot camera is how SLOWWWWWWWW it took to save each photo before I could take another.. If waiting a few seconds between each picture is a non-issue, buy all means save some money and buy this card.

Bottom line: You're wasting your money buying this card to use in a high resolution point and shoot, which they all seem to be now days. Just too slow!

Fast Card, November 21, 2007
I have this card. This is extremely fast card. I did a test on my laptop sd slot writing 6 gb files onto the card. Average speed was 5mb per second. that was more than it rated for.

If it was a little faster..., January 19, 2008
I contemplated a 4 star rating, but when you buy the card, you know that it is a "class 4" card, which means it's supposed to transfer files at at least 4GB/s. If it's crucial and you can afford it, you could get the "class 6" card, which would make a difference when transferring large amounts of data.

In short:
*Pros:*
- Capacity. You can get more capacity, but this is a bout the best size/price ratio.
- Price. Again, 8GB and 4GB cards have the best size/price ratio.
*Cons:*
- SDHC. This is not really a con if you have new equipment, but SDHC is a newer standard, so you have to make sure you have the right equipment - SDHC IS NOT THE SAME AS SD!!
- Speed. It's not "slow", but if you've had fast cards you'll notice the difference. Of course, you know this from the "Class 4" rating, so it's also not really a con.

I've owned 2 Kingston SD cards. The oldest of them is about 3 years old and is still as reliable and good as when I first got it, so I have reason to believe this card will last for a while.

My older Kingston 50X SD card is about twice as fast as this card, but it's only 1GB, so I needed more GB's to capture more video. This card would be just about perfect if it was faster. When I say that, I don't mean that the card is slow - my Vista machine can use it for ReadyBoost and camera performance is good. Just know that ReadyBoost can only use 4GB of memory, so you'll have 4GB of memory just sitting unused if you use it for this purpose.

Primarily, I use this card for recording video clips and pictures with my Canon cameras, SD800IS and A710IS. For that purpose the card is great. I haven't noticed any lag when taking 7.1 Mega-pixel pictures (which range from 1MB to about 4MBs) or full screen VGA video (640x480). Here's some general advice for these cameras in particular, but it applies to most cameras:
1. Don't record more than about 10 minutes of video at a time because the file size goes over 1GB, but this depends on the camera and video format, not the card itself.
2. You might want to get an external card reader, if you don't have an internal card reader. You'll be fine transferring files directly from the camera if you only take a few snapshots and short videos. But if you plan on truly using all 8GB and transferring them at once, do yourself a favor and get a card reader. Most cameras are not meant to read/transfer files at fast speeds (even if they're USB 2.0 capable), and at least with the SD800IS, I could not transfer files over 500MB. Once I used a memory card reader, transferring was a breeze.

Although reading times are fast enough (between 4-8MB/s), writing is a bit slower - it tops out at about 4MB/s, which is good enough for the "Class 4" rating and fast enough to capture pictures without (noticeable) lag in my cameras.
It's a great card for the price; just make sure you understand what you're buying.

Don't be swayed by idiot customers.., February 25, 2008
I like our point and shoot camera to be low thought-low effort (big SD card, high capacity rechargeable battery, reliable point and shoot performance, etc.), and this 16 gig card coupled with our Canon SD770 has been a great combination. Almost 1000 pics on our vacation to Punta Cana, and the card wasn't filled (I could do the math, but I don't want to).

The card has been reliable, worked fine in a card reader, and I'd make the purchase again. I can't believe this little card holds 1000's of times more information than information storage from only a short time ago, and cost me ~$20. Amazing!

Excellent for the price. I give it a 4/5 because it performs slower than expected from a C4 SDHC card. I also have a Sandisk EIII 2GB. Although it doesn't have the class ratings because it's not SDHC, the Sandisk outperforms the Kingston in both read/write.

My test scenario: Using a Nikon D80 taking 6 shots continuously. The Kingston took considerably longer to write contents from the Nikon D80 buffer.

If you're looking for a high speed card in a similar scenario, then look elsewhere. However, if you want a good card and no particular need for speed, then I recommend getting.

does the job, but not good enough..., December 23, 2009

1. Don't record more than about 10 minutes of video at a time because the file size goes over 1GB, but this depends on the camera and video format, not the card itself.
2. You might want to get an external card reader, if you don't have an internal card reader. You'll be fine transferring files directly from the camera if you only take a few snapshots and short videos. But if you plan on truly using all 8GB and transferring them at once, do yourself a favor and get a card reader. Most cameras are not meant to read/transfer files at fast speeds (even if they're USB 2.0 capable), and at least with the SD800IS, I could not transfer files over 500MB. Once I used a memory card reader, transferring was a breeze.

Although reading times are fast enough (between 4-8MB/s), writing is a bit slower - it tops out at about 4MB/s, which is good enough for the "Class 4" rating and fast enough to capture pictures without (noticeable) lag in my cameras.
It's a great card for the price; just make sure you understand what you're buying.

Don't be swayed by idiot customers.., February 25, 2008
The Kingston 4gb SDHC memory card, like all other Kingston products, is an exceptional piece of equipment. I use it with my Canon SD1000 and I get nothing but blazing fast write times and no headaches. Make sure your device supports SDHC because if not, it will not work. This is a key reason why people are left "unsatisfied" by what they get, not because of the product, but because they did not do their homework.

Buyers, you should really take note that, most reviews on any site about not only Kingston, but other great brands, is heavily altered by idiot customers leaving comments to attack the site that sold them the items. So don't quickly judge an product based on how many stars it has, because honestly, you cannot take that into consideration unless you have read every review posted.

great value at $22, December 3, 2007
The price of the SD4/4GB card jumps around a lot here. It is a great value at $22. Not so hot at $40. Wait a while and it may go down again. Note that only newer SD devices can use the 4GB SDHC cards. Older cameras, etc. can only use regular SD cards up to 2GB. If you're not sure, check your owner's manual or contact your manufacturer. Also, older SD card readers will not work with SDHC cards, but SDHC card readers are available for about $10 on amazon.com

Unreliable - Disappearing Pictures, December 12, 2008
I had this card in a Panasonic DMC-TZ5 camera for about a month, and in that time the card experienced a "read error" on three separate occasions that resulted in all the pictures currently on the card disappearing. I called Panasonic customer service and the first question they asked was what brand card I had. When I told them Kingston, they advised me to get a new card, as nearly everyone who complained about disappearing pictures (in any model camera) had a Kingston card. I'd much rather spend a little more money and actually have my pictures!

A great bargain, and didn't fill up after 1000 pics!, January 21, 2009
I like our point and shoot camera to be low thought-low effort (big SD card, high capacity rechargeable battery, reliable point and shoot performance, etc.), and this 16 gig card coupled with our Canon SD770 has been a great combination. Almost 1000 pics on our vacation to Punta Cana, and the card wasn't filled (I could do the math, but I don't want to).

The card has been reliable, worked fine in a card reader, and I'd make the purchase again. I can't believe this little card holds 1000's of times more information than information storage from only a short time ago, and cost me ~$20. Amazing! ... Read more

Editorial Review

Performance and capacity redefined with Kingston's SD High-Capacity memory cards.

Starting at 4GB, SDHC cards offer larger-volume data storage and optimized recording performance with support for FAT 32 file formats. In addition, Kingstonâ?TMs SDHC cards use new speed "class" ratings known as Class 2, 4 and 6 that deliver a minimum data transfer rate for optimum performance with SDHC devices.

Although identical in size to todays standard SD card, the new SDHC cards are designed differently and are only recognized by SDHC host devices. To ensure compatibility, look for the SDHC logo on cards and host devices (cameras, camcorders, etc.).

For added reliability and durability, our solid-state SDHC memory cards are built of nonvolatile memory components and have no moving parts that could wear out or break. All cards are 100-percent tested and are backed by a lifetime warranty and free live technical support. ... Read more

Kingston quality, massive storage, what's not to love?, December 2, 2008
There are some things to consider before buying this particular card or any other 32gb SDHC card on the market:

1. This is NOT an ideal card for a digital SLR like a D80, D90, Rebel XT, etc... That is because it is a class 4 device. The class of a SDHC cards has to do with how fast they read and write files, not how much storage they have. For a digital SLR, you should purchase a class 6 SDHC card most of the time. Class 6 cards will allow you to take 'bursts' of photos and not be limited by the card's capacity to write them. Also class 4 cards are slower reading data, meaning they will take longer to upload files to your computer. Upload speed is convenient, especially when loading large batches of files.

2. This card has far more storage than most people will need for their digital camera. Unless you like to keep all your photos on a SDHC card and never move them to your computer, or are a high volume photographer, there is very little need for more than about 8gb of storage space for most caeras. The possible exception to this is if you have a professional SLR that shoots files in the 16-20mb range--but if you do, you'll likely want a class 6 card anyway. If all you intend to use this card for is a digital camera, save yourself a lot of money and buy a PNY 8GB SDHC Card. If you're worried about running out of space on a vacation, buy a few of them. Otherwise you run the risk of having 'all your eggs in one basket.' If one card fails, you lose all your pictures instead of only a portion of them.

This card is fantastic for use in a video camcorder capable of writing to an SDHC card. (Check with the manual first to insure that a class 4 card will be fast enough first). It is also perfect as extra storage for an ultra portable computer or net book like the Asus EEE pc. Another great application would be as added storage to a personal media player or MP3 player equipped with a SDHC slot such as the Cowon D2.

There are other good 32gb SDHC cards on the market, some at cheaper price points than the Kingston card. IMHO, brand matters very little with something like a SDHC card, since they all are made pretty much the same way. None of the brands currently offering them (Transcend, PNY, Kingston) have high fail rates with their other products, so I believe they are all pretty similar. What you decide to buy will depend on whether you trust a particular brand, or who has the lowest price. All of them will work equally well.

Very Big, September 8, 2008
PREFACE:

I bought this card for extra disk space on my Asus EeePC netbook. I needed as much space as possible to supplement the very small SSD hard drive. I needed something with large capacity and relatively fast file transfer time.

PROS:

It shares the largest SD capacity on the market today with few others (Panasonic, Sandisk, and PNY) and is a quality name that I have had a good history with in the past. Its file transfer time is similar to the SSD drive in my machine so it basically acts as a second SSD for me at less than a quarter of the price!

CONS:

Its not the cheapest 32gb SD card(PNY) nor the fastest(Panasonic) but its good quality with a decent transfer rate.

CONCLUSION:

I'm very happy with its performance and capacity. I would like to see the price come down a bit, but that's the price of getting electronics of this caliber.

That's my input, take it or leave it :)

Good for the money, but don't expect fast speeds., December 8, 2007
Excellent for the price. I give it a 4/5 because it performs slower than expected from a C4 SDHC card. I also have a Sandisk EIII 2GB. Although it doesn't have the class ratings because it's not SDHC, the Sandisk outperforms the Kingston in both read/write.

My test scenario: Using a Nikon D80 taking 6 shots continuously. The Kingston took considerably longer to write contents from the Nikon D80 buffer.

If you're looking for a high speed card in a similar scenario, then look elsewhere. However, if you want a good card and no particular need for speed, then I recommend getting.

does the job, but not good enough..., December 23, 2009
I have this card. This is extremely fast card. I did a test on my laptop sd slot writing 6 gb files onto the card. Average speed was 5mb per second. that was more than it rated for.

If it was a little faster..., January 19, 2008
I contemplated a 4 star rating, but when you buy the card, you know that it is a "class 4" card, which means it's supposed to transfer files at at least 4GB/s. If it's crucial and you can afford it, you could get the "class 6" card, which would make a difference when transferring large amounts of data.

In short:
*Pros:*
- Capacity. You can get more capacity, but this is a bout the best size/price ratio.
- Price. Again, 8GB and 4GB cards have the best size/price ratio.
*Cons:*
- SDHC. This is not really a con if you have new equipment, but SDHC is a newer standard, so you have to make sure you have the right equipment - SDHC IS NOT THE SAME AS SD!!
- Speed. It's not "slow", but if you've had fast cards you'll notice the difference. Of course, you know this from the "Class 4" rating, so it's also not really a con.

I've owned 2 Kingston SD cards. The oldest of them is about 3 years old and is still as reliable and good as when I first got it, so I have reason to believe this card will last for a while.

My older Kingston 50X SD card is about twice as fast as this card, but it's only 1GB, so I needed more GB's to capture more video. This card would be just about perfect if it was faster. When I say that, I don't mean that the card is slow - my Vista machine can use it for ReadyBoost and camera performance is good. Just know that ReadyBoost can only use 4GB of memory, so you'll have 4GB of memory just sitting unused if you use it for this purpose.

Primarily, I use this card for recording video clips and pictures with my Canon cameras, SD800IS and A710IS. For that purpose the card is great. I haven't noticed any lag when taking 7.1 Mega-pixel pictures (which range from 1MB to about 4MBs) or full screen VGA video (640x480). Here's some general advice for these cameras in particular, but it applies to most cameras:

I didnt realize how fast the point and shoot cameras are getting sooo many megapixels until I started looking for a good one for my mom... This card is no good for a 12 megapixel camera! It takes way too long to save each picture slowing down how fast you're able to take consecutive pictures! Go for the Sandisk extreme cards and dont look back!

I only have SLR cameras, and use the San Disk extreme cards because speed is crucial! Dont cheap out on a card after buying a nice camera, or you'll be sorry! Thats the first thing i noticed when showing her how to use her new Canon Point and Shoot camera is how SLOWWWWWWWW it took to save each photo before I could take another.. If waiting a few seconds between each picture is a non-issue, buy all means save some money and buy this card.

Bottom line: You're wasting your money buying this card to use in a high resolution point and shoot, which they all seem to be now days. Just too slow!

Sandisk 8GB SDHC Memory Card ... Read more

Reviews

Great Class 2 card, but make sure you have an SDHC reader., June 2, 2008
Please note that this is a Class 2 card (Class 6 is the current "top of the line"). Class 2 transfers two mega-thingies per second rather than the six mega-thingies per second for Class 6 cards.

This transfer rate is fine for most devices, but takes 3 times as long to copy files back and forth from your computer.

Please also note that older card readers are not able to handle SDHC (HC stands for "High Capacity"). Some card readers are good for only 1 GB, some go up to 2 GB or 4 GB, but only the latest generations are capable of 8 GB.

Lastly, if you are using Windows XP, you may need to either add Service Pack 3 or add a patch before the high capacity card can be recognized by your system.

I recommend adding the patch rather than SP3. Some things haven't been working quite right since I installed the latest service pack from Microsoft - you may not wish to take that chance...

Sandisk 8GB SD Memory Card Works Well, March 25, 2008
8GB is more than enough for my Canon PowerShot. I recently went to New York City for vacation and took more than 250 plus pics with the best pixel quality the camera could provide and still had more than enough memory left. Highly recommend this product. You don't need to carry any extra memory.

8 gig SDHC card works very well!, March 25, 2008
I found the performance excellent and the size very compact to carry about without difficulty of damage or weight reduction on travel. The price too is very competitive compared with in-shop prices.

Great Product, July 6, 2008
This is the best value for the quality for a SD card of this size. I Highly recommend this to anyone that needs storage. I purchased this for my Nikon D40 Digital SLR camera, and it works beautifully. I have plenty of room to storage photographs.

Works as it should!, July 1, 2008
What can I say? This product works perfectly in my Canon FS100 camcorder. No issues with corrupt data (knock on wood) and the write speed is adequate...no delays noticed during camcorder use. Sure, there are cheaper SDHC cards out there but I have used Sandisk in the past and have never had a problem with them.

8Gb memory for camera, June 30, 2008
Great so far. I went to an air show in Anchorage and I was able to do a lot of videos.

Beware, December 4, 2010
The price looks good but this company eats you alive on shipping in my opinion. I received 2 SD cards ( 1.2 x 2 x 3.8 inch total, this counts their clear protective slips, and these were shipped in a 5 x 8 bubble mailer using USPS First Class. For this the company charged $11.90. REALLY? COME ON.
Do not fall for this. Amazon needs to address these guys who overcharge for S/Handeling or face customers moving on.

SanDisk 8GB SDHC problem, September 16, 2009
This card was purchased in 6/09 for use in a new Canon 780IS camera that IS sdhc compatible. At first it worked great and it was wonderful to have such a large amount of memory available for stills and video. then after about a month it got glitchy and I received intermittent memory card error messages that would resolve by removing and reinserting the card. After another 2 weeks it is useless, won't read, won't write not in the camera nor in my computer (where it worked fine before). It's not the camera because all the other SD/SDHC cards I've tried work fine. I know Sandisk has a 5 year warranty, but like a trusting person I did not keep the receipt so I guess that's that. Pity because i have never had problems with Sandisk products before. ... Read more

Sony Memory Pro Duo II - Fast But Expensive Memory for Your Sony Devices, June 2, 2008
At Least two of the Sony Packaged Memory's Pictured here on Amazon are FAKES or COUNTERFITS.

UNUSABLE MEMORY.

The people that make these are taking non-sony generic crap 512's, 1,2,or4 G size chips
and creating very elaborate nearly perfect (looking) FAKES! Zoom in and look very closely
at the model numbers for the 8 and the 16 Gig. In the third and forth images you can plainly see
the fake model numbers I have shown below.

Their numbers do not exist in the True Sony lineup.

for example: MSX-M8GST/X & MSX-M16GST/X do not exist <<< BOTH ARE FAKE

Dont believe me,, go look it up for yourself ,,, GOOGLE it or look at the links below.


THE NUMBERS SHOULD SAY

for MARKII MS-MT8G & MS-MT16G Also there is an 8g that is not MARKII it is MSX-M8GS/X << older model.

There is never a T toward the end of the model number in these particular Larger memories,
and NO MARKII's ever have a /X or a MSX !!! in the model # at all!
This fake erroneous numbering scheme was barrowed from the 1G MSPD which has the number > MSX-M1GST/X

and from what I can tell is the only Sony Stick to EVER have the T in that location!

Take the time to look at these links which are both VERY, VERY Informative on the Subject.
Look In Comments for them:

You should also know there not just doing these Sony Memory Sticks. Sandisk and Lexar as well as all forms of

This 16GB Memory Stick Duo II card works great with the PSP portable gaming system. It comes pre-formatted, so all you have to do is stick it into your PSP and go. In fact, there is a picture of the PSP right on the packaging.

The usable space on this device is actually 14.9 GB, however.

The "Mark2" certification on the card has to do with higher writing speed requirements and indicates the memory is certified to operate with AVCHD recording products.

Bought this for my PSP, May 15, 2008
This is currently the only available 16GB Memory Stick. I bought it for my Playstation Portable in order to replace an 8GB Memory Stick.
Regarding the price you can easily argue that it is much cheaper to buy two 8GB Memory Sticks. And for any person who is concerned about spending money I would not recommend this product.
At the time I bought it, Amazon was offering the best price online. Regarding the fact that this Memory Stick is about $50 more expensive than the PSP itself, makes you think twice. But my sole purpose was that I wanted to keep things together: my music, videos and saved games etc.
This Memory Stick is large enough to satisfy my thirst for disc space with a single solution.

The Memory Stick works fine in my PSP. Before this one I used a Sandisk 8GB Memory Stick Pro Ultra and I cannot see a difference in read/write speed (while connected through USB to my PC).

Final thoughts:
If you are concerned about spending money and you can live with more than one MS for your gadgets, you should get two or more 8GB MS. If you want a single solution and price is of no matter, get this one. Since it is from Sony you can be sure it works with your MS-enabled gadgets.

Pro:
- high capacity
- read/write speed is up to par with other (higher ranked) memory sticks (using the PSP USB connection!)

Con:
- not cheap

5 out of 5 stars; simply because the price does not matter to me

(My guess is that the price will drop to about $150 once other manufactures offer similar capacity.)

Fake 16GB memory stick pro dua from Amazon directly, July 15, 2009
I'm aparently also a victim of the fake cards. Ordered the 16GB Sony memory stick pro duo directly from Amazon. Received it (unaware of fake cards going around), formatted it in my PSP without problems. Then tried to load data to the card via my card reader. Card reader didn't recognize the card. Card reader was old so purchased a new one from Best Buy. Recognized the card but transfers were incredibly slow and data got corrupted. Checked with manufacturer of reader and they indicated they only tested up to 4GB. Bought yet another reader with guaranteed support for all speeds and capacities. Same problem. Checked online and found out about the fake cards. I already threw out the packaging believing the card readers to have been the problem. Amazon was kind enough to still ship me another card. Will wait and see if it is a genuine one. I would never have expected Amazon to be selling fake items...

READ BEFORE YOU ACT!!! BEWARE OF FAKE CARDS!!!
I bought this Sony MSMT16G 16GB Memory Stick PRO Duo (Mark2) Media Card from one of Amazon "Featured Merchant". It came with a very original look like packaging, even a hologram on top. As soon as I insert it in to my video camera it did not recognized. I tried another same type camera and also a media card reader with no luck at all. Then I found lots of information on the net saying there are fake ones which won't work with cameras and else. So be careful don't buy a fake one, like me.

Real Authentic Memory card., July 14, 2008
I bought this mainly for my PSP. 16 gigabytes is very sufficient to store tons of movies and games and the best thing is there aren't any glitches at all. :D

16 Gigs of Satisfaction, July 16, 2008
I bought the Sony 16GB Memory Stick PRO Duo for my PSP and I feel like I almost have too much space for pictures, game saves, music, and movies. Because of the 16GB of storage space, my PSP now rivals my iPod Nano plus I can fit a hand-full of full length films on it. More storage space is definitely a good thing; I am very happy with my purchase.

Sony Memory Pro Duo II - Fast But Expensive Memory for Your Sony Devices, June 2, 2008

Even though I have been slowly weaning myself off of the newer Sony cameras, I still have some Sony devices that need memory pro duo cards. There are some advantages and a few disadvantages, namely the cost and availability. Sony's memory format averages 30 to 100 percent higher prices for the same capacity of SDHC cards. While that sucks, if you have a Sony Camera or a PSP there's not much you can do about it.

To that point, both the new Sony Cybershot DSCT300 Digital Camera and upcoming PSP God of War Entertainment Pack will benefit from any of these memory cards. Both of those devices, along with most Sony devices for that matter are only comaptible with the memory duo platform.

But like I said, if you need one of these cards, there are some advantages especially if you get a Mark II card. Namely, the performance speed of the mark II format is about 50% higher than the fastest available SDHC card at the moment. The rating is for 36 MB/s and what I've seen through some basic tests seems to indicate real performance close to this. In fact, the solid performance has to be the biggest pro for these cards. So while it sucks to have little choice, when you factor in the premium performance it's easier to swallow.

The 2 and 4 GB cards are a better value than larger capacity ones right now. Sometimes you want the largest card you can get, but till the 8 and 16 GB cards come down I see no reason to buy them. Not to mention, this isn't for my primary camera but for an older one that I use as a backup.

Make sure your device is compatible with the card. Some older electronics aren't compatible with larger capacities, although in general Sony has been better with making these guys backward compatible than others.

It's always a good idea to have several extra cards on hand just in case. This 4 GB card is a nice performer. If you have a high capacity camera (10 Megapixels or more) and are storing videos or RAW images, the extra cash for the 8GB card may be worth it if the price is right. Or you may want to step up to the larger 16 GB size that is now available. But if you wait a little longer you can save yourself some cash. I have to take off at least 1 star for value, but in terms of performance I couldn't be happier.

Enjoy!

Beware of FAKES, January 13, 2010
At Least two of the Sony Packaged Memory's Pictured here on Amazon are FAKES or COUNTERFITS.

UNUSABLE MEMORY.

The people that make these are taking non-sony generic crap 512's, 1,2,or4 G size chips
and creating very elaborate nearly perfect (looking) FAKES! Zoom in and look very closely
at the model numbers for the 8 and the 16 Gig. In the third and forth images you can plainly see
the fake model numbers I have shown below.

Their numbers do not exist in the True Sony lineup.

for example: MSX-M8GST/X & MSX-M16GST/X do not exist <<< BOTH ARE FAKE

Dont believe me,, go look it up for yourself ,,, GOOGLE it or look at the links below.


THE NUMBERS SHOULD SAY

for MARKII MS-MT8G & MS-MT16G Also there is an 8g that is not MARKII it is MSX-M8GS/X << older model.

There is never a T toward the end of the model number in these particular Larger memories,
and NO MARKII's ever have a /X or a MSX !!! in the model # at all!
This fake erroneous numbering scheme was barrowed from the 1G MSPD which has the number > MSX-M1GST/X

and from what I can tell is the only Sony Stick to EVER have the T in that location!

Take the time to look at these links which are both VERY, VERY Informative on the Subject.
Look In Comments for them:

Purchased this for my Sony Cyber-shot DSC-W150 camera based on the 25 great reviews before me. (Thanks, reviewers... I wasn't exactly sure what I was doing because the documentation that came with the camera didn't provide any help on how to buy memory!) I thought $38.50 was a great deal. It does the job and allows me to record video clips without feeling like I'm eating up all my memory. (For reference, about a minute and a half of video uses up about 200 shots out of the 2,500+ shots. Though I don't know if the resolution settings, etc. are factored into that estimate).

Editorial Review

This telephoto zoom lens is designed with Canon's Optical Image Stabilizer technology while retaining compactness and lightness, in response to demands of photographers. This high zoom ratio lens is equivalent to a focal length of 88-400mm in the 35mm format (when used on Canon EOS cameras compatible with EF-S lenses), and the image stabilizer effect equivalent to a shutter speed about 4 stops faster than the same size lens without Image Stabilizer. In other words, if the slowest shutter speed you could formerly hold a 250mm lens steadily was 1/250th of a second, with Canon's 4-stop stabilization correction, you could hand-hold at shutter speeds as slow as 1/15th of a second. It also uses a UD-glass lens element to correct chromatic aberration for excellent image quality throughout the zoom range. This new EF-S telephoto lens with great features delivers excellent performance at an affordable price for all photographers. ... Read more

I Love It For IS and Zoom Range at this Price, Not Pure Performance, March 18, 2008
I was determined to love this lens based on the specs and price point alone. Canon really needed to come out with this lens at this price because Nikon offers a very decent Vibration Reduction lens at roughly the same range for the same price, leaving me to make apologies for Canon and their neglect to all my Nikon friends.

The IS can be switched off to save battery life but I haven't noticed a difference in battery performance with it. The IS is only activiated when you press the shutter halfway for auto focus. Although it FEELS like there is a small lag for the IS to start, I don't think I've had any photos messed up because of it.

You can HEAR the IS. A little bizarre after using point and shoots that have IS that is silent, but it doesn't seem to affect performance

Pro: Great price for an image stabilized zoom lens. I paid 299 and am very pleased even though Amazon is selling it for 280 a week later. ALso arrive 2 months sooner than Amazon initially promised. This lens has NEVER been 400 dollars. Its MSRP from Canon prior to release was 299.00. Shame Amazon!

Pro: Images are very sharp.

Pro: Image stabilization does a VERY nice job. Four stops as advertised by Canon? I'm not so sure. GREATLY enhancing the composition experience at 250mm? Absolutely.

Pro: Much smaller and lighter than the 70-300 of any manufacturer and much sharper than my Sigma 70-300.

Con: Cheapish feel. But just use it, quit feeling it already. Plastic mount. But if you NEED a metal mount, may I suggest you are being a little rough with your camera. *UPDATE* The plastic flanges on back were able to hold the camera securely to the lens, but NOT hold the rear cap securely to the lens. I've tried many different rear lens caps that fit snugly on other lenses. So I think this is beyond cheap feel and has to be called CHEAP BUILD.

Con: This lens is a little (ok, maybe not so little) slow to focus in dim light, sometimes it misses altogether when I think other lenses of mine would have had no difficulty.

Con: I never gave Inner Focusing much thought on my other lenses until I used this. The front of this lens rotates AND moves in and out a LOT while focusing, so much so that you MAY even want to recompose your shot. The length of this lens changes almost an inch across the focus range. I just checked my Sigma 70-300 and found that it does also, but I've never seen it make as much difference in the viewfinder as I have with this Canon. Your perception may vary.

This lens and the soon to be arriving 18-55 IS as the XSi kit lens will allow me to carry one less lens to achieve an 18-250 IS range. For a little more money than the cost of both lenses you can get the Tamrom 18-250 but not have Image Stabilization. And now Sigma has an 18-200 WITH Optical Stablization for about what these 2 lenses cost retail, but in testing the 2 Canons produced better images.

Conclusion: A great EF-S lens for Canon users. (even if Nikon had to force Canon to make it for us.)

Great telephoto lens to complement your kit lens, February 5, 2009
This is the first lens that I've purchased and kept outside my kit lens (18-55). I mentioned kept because believe it or not, I bought the 70-200 F4L non-IS. I won't be giving any technical review about this lens as that is pretty much covered by the other reviewers here. I'll just share my story to help out other beginners who are having a hard time as well contemplating on what lens to get to complement their kit lens.

At first, I definitely wanted to buy a telephoto lens so I can shoot objects from a distance and I really like to try the lens out in a zoo. I then narrowed my choices between EF 70-300 IS USM and 70-200 F4L non-IS (didn't want 55-250 then because I didn't like the plastic mount). Since the latter would end up costing almost the same or even less (comes with hood and pouch plus the free filter amazon offers), I went for it without even thinking. Before the package arrived, I already had second thoughts and tried to cancel the item. Since I tried out the amazon prime 2 day shipping, the package came really fast so I wasn't able to cancel but returned it as soon as I got it.

So why did I return the 70-200 F4L and settled for an EF-S 55-250?

- I don't get paid taking pictures, it's just a hobby.

- No one will really sit down and scrutinize the pictures I take. All Canon lenses take great shots compared to other brands. It's not like I'm posting the pictures I take in the net for public view.

- The beige color of the L lens is somewhat too loud for me. I don't want people to think I have that much cash or evern comment that I only have an XS body.

- No IS, I realized that I really need IS because I don't have any plans of getting a tripod soon and my hands are really shaky.

- Cost!

- Weight.

- Performance of 55-250 that I was able to research over the net. Of course it's nothing comapred to the L lens, no doubt about that. But if the pictures are viewed alone, without comparing to L lens, they are great.

- Max range is only at 200, I get an extra 50mm with 55-250.

- Missing the 56-69 mm.

Ok, the last 2 are just for my piece of mind because I opted with 55-250 but they don't really matter if you have the L lens. If you do become a pro in the future, you'd definitely get something better than the 70-200 F4L.

Bottom line, this lens is no where in the league of L lenses. As one of the reviewers mentioned, it does the job. For value of money, I really love this lens. About the plastic mount, I realized that I wouldn't be using my camera that hard anyway. Plus, it'll be lighter.

I'm going to steal one of the reviews I read, it basically says that if you like the performance of your kit lens (18-55), you'll defintely like this as well. I totally agree, fast AF, sharp pictures, longer range version of 18-55.

Note that this is NOT a comparison between L lens and 55-250, or even 70-300. Just a decision experience that I wanted to share with a number of beginners out there.

reasonable value, May 6, 2008
Since I mostly use wide-angle lenses, I was not willing to blow a ton on expensive/heavy telephoto lenses for occasional shots. Prior to owning this lens, I had a Sigma 70-300 APO zoom telephoto that produced good colors, but was essentially useless due to frequent camera shake. I sold the lens and got this Canon zoom.

a) Surprisingly, it CAN produce pretty sharp pictures if the subjects don't move fast. The sharpness is very comparable with two other lenses I own, the famed and breathtakingly sharp Tamron 17-50mm f/2.8 and Sigma 30mm f/1.4. While the Tamron and Sigma get sharp shots without too much work, this Canon needs a bit of careful handling to get equally sharp shots even at the wide end. I use the word "can", because to achieve it you would either need a tripod or high ISO (my rebel XT's 1600 is pretty much what I use all the time with this lens).

b) The colors in bright light are almost always faded (sharp, but faded). It can be patially corrected in Lightroom, but a bit unfortunate since this lens really needs the bright light for a good shutter speed. Indoors, it produces good color balance/saturation, but struggles to have a decent shutter speed. Kind of catch-22 situation.

c) The construction is pretty cheap, but generally nothing to worry about if handled gently. However, the filter threads are thin plastic and I almost damaged the threads when putting on filters for the first time. I got a dedicated Sigma DG 58mm UV filter permanently affixed on it so that any other filters/screw hood will only go on the metal thread of the UV filter and not the lens thread directly. A metal UV filter is a must if you don't want to permanently damage the lens filter threads.

d) The opteration of the IS is quiet unless you are particularly listening to it. My Tamron's AF makes more noise.

e) After playing with this lens for sometime, I have come to the conclusion that IS is an absolute must on a zoom telephoto when hand held. Being the cheapest IS telephoto on the market today, there is really no equivalent for this in this price range.

f) IS has been of no use in freezing subject motion. While this is to be expected, it highlights how slow a lens this really is.

g) No hood comes with the lens, but I got a third party 77mm screw telephoto metal hood and step up adapter rings.

h) 1 year canon warranty sucks big time compared to the 6-year Tamron and 4-year Sigma (for DG lens).

i) this is a very light lens, much lighter than my sigma or tamron. Very easily carried around (hood might add a bit more bulk, but not too much).

In short, this lens performs great with regards to sharpness and IS. It leaves a lot to be desired in color saturation and flare control, almost always requiring some kind of post processing to achieve desired result.

Update 10/22/08
----------------
I bought a 58mm Canon 250D close up filter for this lens and now I have a fantastic macro lens, that is capable of doing 1:1 macro with a working distance of 25cm (~10")! The 250D is roughly 1/7 th the price of the closest 1:1 macro lens with the same working distance - the tamron 180mm 1:1 macro if you were planning on getting a seperate macro lens. The 250D is optically optimized for lens up to 135mm focal length, but the results are fantastic handheld up to 200mm on this lens. Using 250mm (when you get a bit higher than 1:1) is a little bit of work, but gets decent results (with mirror lockup + tripod + f/25). No horrible color fringing that happens with cheap closeup filters on the market (like the Opteka +1,+2,+4, and +10 close up filters). I haven't used a true 1:1 macro lens, which I suspect will definitely be better quality-wise, but the combination of a canon 55-250mm IS + canon 250d for a telephoto + 1:1 macro + IS under 400$ is a true bargain along the lines of the 50mm f/1.8.

Which lens to get, June 15, 2009
I have a 18mm-55mm lens, and was in search for a telephoto, I read so many reviews that were so complex I didn't know what I was reading. I bought the 55mm-250mm lens and now understand some of the reviews.

To break it down in simply terms:

55mm (the lowest setting on the 55mm-250mm) you can not stand right on top of a subject, the lens makes you too close everything won't fit in the frame. That is Not what the lens is for & might be were some of the bad reviews come from. (Buy the 18-55mm for those close up shots)

It takes time for the auto focus, it still Fast but not as fast as my 18mm-55mm. Still your not going to miss taking a picture of a bird sitting in a tree far away. But at baseball game of a kid catching a 50mph ball I missed some shots (why I gave 4 stars). Not the lens fault more mine I should have used manual focus!!

On auto focus, after all it has a LOT of setting to go through 55 to 250mm settings. No duh the 18-55mm auto focus faster. Think of it as a deck of cards, you (and auto focus) can flip through 18-55 cards faster then a deck of 55-250 cards. Some of the reviews complain about the auto focus, it does work of course just not as fast as smaller lens.

No matter what if you are in the back row and your son on the stage at a school play, your picture will be Prefect and it will look like you were in the front row.

That is what this lens is for, where you can take time to set it up, adjust and take time to snap a picture. At a baseball game you need to use Manual focus, (you can turn the ring faster then auto) and you can get great pics, auto might let you down during fast action but not with still pictures!!

I suggest getting 18mm-55mm for everyday use, for those great up close, fast action, birthday shots; I Love that lens. Then get the 55mm-250mm for those far away school plays, scenery vacation, and birds sitting in a far away tree the lens is prefect for those kinds of pictures.

Excellent value, June 13, 2008
This is a very good lens given its price. Like with any lens selection there
are compromises, and a more expensive lens is not necessarily better in all
respects. These are the main considerations for me:

* The lens comes with an excellent IS. One could probably save a hundred bucks
buying a non-IS lens in this focal range which may even be a bit better optically.
However, long range shots without IS are difficult, especially in low light. The
IS on this lens works very well, better compared to my Canon 28-135 IS and even
compared to the 100-400L. The IS really makes a lot of hand held shots possible
that one could not do with a non-IS lens.

* The lens is fairly cheaply built and has a plastic mount. However, the
trade-off is that it is also fairly small and light (the small size is also due
to the fact that it is a EF-S lens). My other tele-zoom is a 100-400L lens
which is built like tank, but it is also huge and weighs 3 pounds. In many cases
one does not want to carry that much weight around, and that is where this lens
comes in really handy.

* Image quality: No, it cannot quite match the 100-400L, but it comes surprisingly
close. Of course, the 100-400L costs 5 times as much. Lack of good color
saturation is the most notable deficiency. On the other hand images are very sharp.
For outdoors one should get a hood, there is quite a bit of glare in shots with
frontal sunlight.

* Zoom range: the 55-250mm range makes the lens quite versatile. 250mm is long
enough for most outdoor sports, many nature shots, people from afar, etc. At the
other end 55mm is still good for close action, for example at a soccer field.
That is almost a factor 2 shorter compared to 100-(300/400) lenses.
It also provides a nice overlap with walk-around lenses, like the Canon 28-135 IS.

* Aperture: F4-5.6 is nothing to brag about, however, a faster lens would also
have to be much bigger, heavier, and costlier. And as long as you objects don't
move too much the IS makes the lens effectively faster. If Canon's 4 stop
improvement holds it would be equivalent to a non-ISF1-1.4, although F1.4-2 is
probably more realistic. A F1.4-2 with that focal range would have to be big,
heavy, and expensive, if it even existed.

In summary, this is an excellent second lens to complement a short zoom or a
walk-around lens. Very versatile and a lot of bang for the buck. In my case,
even though I own a 100-400L I still keep this lens because it is often more
practical because of the shorter focal length and the smaller size.

The Good and The Bad..., March 26, 2008
I have had this lens for a couple months on my XTI. I purchased it from Canada and it has North American warranty (both Canada and the U.S.) so I'm safely assuming it will be the same lens released here in May.
After hundreds of shots so far here are my thoughts:

The bad:
-On my copy the color is off. Skin colors have a slight gray hue and colors are not very saturated. In order to get vibrant hues post-processing is necessary.
-Front element rotates and extends while zooming
-It is an EF-S lens. Are you planning on upgrading to full frame soon? I am not so this is not necessarily "bad" but can be to those who are uninformed about the compatibility issues with this lens.
-People often complain about the quality of the plastic build. I am okay with it since this lens is a place holder until I have the money for an L class lens. I would rather have this lens now so I can capture the photos in this range than wait 6 months to a year until I can drop a couple grand on the lens I really want.
-Although it overlaps some with my Tamron 28-75 (which I absolutely adore)I like having the versatility to get a bit wider with this lens. It keeps me from carrying an extra lens when I know I will be shooting at the longer end but I still have the freedom to zoom out a bit to get more landscape if the moment strikes me.

The good:
-Sharp photos
-Decent bokeh
-IS is amazing on this lens. Shot a performance on a dimly lit stage at the long end of the zoom (5.6) without the flash and 85% of my images came out sharp. However, please realize IS controls the PHOTOGRAPHER'S shake/movement NOT NOT NOT the movement of the subject. So with the 15% of the images that weren't sharp (or flat out blurry) the subject moved at a decent rate. If you want to stop movement in less than bright environments a faster lens (2.8, 1.8, or 1.2) is necessary. Also, on my copy the IS is dead silent and I do not have the noise problem the other reviewer was describing.
-For the PRICE you will not find another lens in the 50-250-ish range with this level of performance, IS, and image quality. OF COURSE the 70-200's are better.. several hundred to thousands of dollars better. Cannot compare with Canon's L class lenses although people will (and have)...

Lost one star because of the less than vibrant colors and other reasons noted above... I almost want to give this lens 3.5 stars because I am not enamored with as many of the photos I have gotten out of this lens as I thought I would. I had the Sigma 70-300 APO (before they made the DG version) prior to this lens and I loved the color rendition. However, the lens lacked IS which cut out its ability to capture numerous shots. The Sigma is now broken and sitting on a shelf in case anyone was wondering why it was replaced.

Good, but not great., May 9, 2008
This lens can be summed up by the simple statement of "Good, but not great." It gets the job done without really excelling at it, and it is definitely not without its issues. That being said, you can't beat the price - depending on what you're looking for.

The price doesn't lie, and though the lens takes good pictures and offers a decent feature-set (IS under $300), it's not a top performer. Bokeh is a bit harsh, AF is somewhat slow and low-light is pretty much out. If you want to make a hobby out of shooting long focal lengths, do yourself a favor and give this a pass.

However, if you're more of a landscape photographer (like me) looking for nothing more than an adequate long-tele lens while you're spending your money on the awesome 10-22mm or a good 17-50mm f/2.8, this lens fits a VERY needed place in your bag.. A 70-200L f/4, it ain't - but it's also not $1,000.

All in all, you get what you pay for and it's good (bordering on sufficient) without being great at anything. It's a terrific buy for someone like me who looks at the tele- end of focal lengths as "that occasional odd shot I don't want to miss." It'd be bloody horrible if I actually used it as a regular lens - but then, I didn't pay the same amount for it that I have for my wider lenses.

very nice long-range affordable telephoto, July 20, 2008
I mainly use prime lenses but my longest lens maxes out at 85mm. So when I saw this lens 250mm (similar to 400mm on full-frame) with a reasonable price, I grabbed it.

The colors are rendered well, the IS works like a charm.

Note - this is an EF-S lens so you won't be able to use it on a full-sensor camera body later - only on the cropped-sensor cameras like the Rebel XTi.

My reason for not giving it 5 stars is that it occasionally gets confused while focusing. (I use spot-focus mostly - perhaps that has something to do with it.) If it happens, I zoom back to 55mm, focus, and then re-zoom, focus and it's all set.

While I haven't had it for long yet, I was able to get some very nice photos with this lens - one close-up shot all the way down a church aisle of someone performing at the other end in front of the church at night, close-up shots of bees in flight, dragonflies, etc.

The front element rotates but I would never think of using a polarizer on a zoom lens like this since you've already lost a lot of light.

Am I happy I bought it? Absolutely.

IS is the way to go, April 17, 2008
okay so granted i just got this lens today and have limited use with it but i also own a canon 70-200 L series lens WITHOUT stabilization and the difference to me was immediately apparent. i am not one to carry around a tripod which is what you need with my other lens in order to get a clear shot all of the time. yes this lens does feel much cheaper and it was! but the point and shoot shots came out much clearer. i did not notice any color differences between the two lens as mentioned in a previous review. and i also gained mm on both ends which fits nicely with the kit lens. i am so satisfied that after one day i have already placed my other lens for sale on ebay. any takers!

great lens Xsi, January 11, 2009
The Canon Xsi package we bought came with an 18-55 fairly fast lens. I wanted a telephoto lens that went to 300 or more for mostly outdoor and sports shots, but the economy tanked... I couldnt bring myself to spend $$$ for my hobby. I started looking at Tamron and Vivitar as a solution, and while I own both for my old analog slr. I wanted to take full advantage of the Image Stabilazation and AutoFocus features on the Xsi. I have mixed and matched camera, flash, and lens brands in the past and knew there might be some issues.

I have used this lens a number of times in High school basketball games. I am very pleased with it. You can buy faster lenses, but for the money... this little lightweight lense is great! I get a few blurred shots when setting courtside at girls games. A few more blurred shots in boys games. But all in all... not many. And usually the blur is the ball or the feet or hands, which add an element of motion to the shot.

This has been a great lens for the action shots I want to take, it is great for the outdoor shots I take while motorcycle touring, is great for low light with a tripod. Shooting in RAW lets me clean up about any mistakes I make with software. (Except for blurred or out of focus shots), no software can fix those. The price was right. I read some reviewers talking about how light weight and cheezy it felt. Hey, I like the lightness of it. I have this sucker strapped to my neck and light is good.

I got a lot of lens for my dollar, coupled with a very capable camera, it is a good combination for recreational photography.

I ordered through Amazon, It was at my door in SC OKlahoma within 3 days.

thanks,

Don't Waste your Money, August 28, 2009
The Power adapter puts to much charging power into the battery pack and over heats the pack and causes a shut down of the camera. The best bet is to buy a second battery pack and charge it through the USB port.

Why bother, October 5, 2009
Adapter caused the camera to "over heat" or stop charging.
However, my main concern is, why bother to get this gadget at all?
Charge with a usb connection when you can and, when no usb port is available, just use regular AA batteries!
Adapters, over-heating, errors, possible damage, another country......it ain't worth it.

Better off getting an extra battery pack, September 4, 2009
I purchased this thinking it would be a good option for charging quickly without having to be near a computer. The reality is that the computer charging "feels" much slower than charging with your computer, but performs to the specs it lists in the manual (3-4 hours for a full charge with the adapter; 7 hours for the computer method).

One thing that I noticed is that the adapter doesn't sit well in vertical outlets. It's very light plastic and doesn't quite support a Mino HD well. I tried laying it horizontally on a power strip, which worked better. The downside was that the screen of the Mino HD got a little scratched up when it got jostled after removing it from the power strip.

For the people who want to purchase an accessory for their Mino HD, I recommend just getting an extra battery pack and charging it through your computer. It'll be more convenient and costs about the same. Losing power when you're in the middle of filming a clip is no fun. I'd say paying $10 for this adapter would be more reasonable for the quality that you're getting. Hope this review helps!

A must for my flip camcorder, November 18, 2009
I realized soon after getting my flip HD that I can find so much to shoot that I burn up a battery pack and need to recharge it and that sometimes it's most convenient to recharge it via a wall outlet rather than a computer. Here are some examples,,,

We went on a week long cruise and I had no computer access but I could recharge with this because there were electrical outlets everywhere.

I was shooting a wedding reception for a friend and forgot to recharge before leaving but by the time the wedding was over I grabbed my fully charged unit where I plugged it into the church wall behind a table and I was ready to shoot the full reception without losing any power.


We went to Myrtle Beach and stayed in a friend's condo. No computer there to recharge but I just popped in my camcorder at night before going to sleep and it was always ready to shoot in the morning.

I have even found outlets at the airport (near soda fountains and vending machines) in a pinch.

Don't get me wrong, it's not that my camera runs out of juice easily, it is, instead, that the cameras owner forgets to recharge it as often as I should.

Negatives: Wish this was made so I could just stick my spare battery pack into it rather than having to plug the actual camcorder into it but I suppose most don't have spare battery packs so that is no big deal. However it would be nice if it somehow left open the option to do both so that I could keep shooting while it charges

it is really lightweight and has,so far, worked perfectly for me.

It works, but I wouldn't spend money on it., January 7, 2010
I only received this item because it was free with the purchase of the Flip video camera. As soon as I took it out of the box, I was grateful that I didn't pay anything for it. It gets the job done, but it's pretty awkward to plug in and have the camera propped up precariously against the charger so that the whole unit will stay in the wall (and subsequently charge). I've heard that it's better for these types of devices to be plugged into an outlet, rather than charging them through the computer's USB port, so I suppose it's useful for that... but it's just an adapter with a USB port, which means that the wall charger for my iPod and iPhone will get the job done just as well.

I would not pay $25 for this item. In fact, if given the chance, I would probably choose a different free accessory. If you're anything like me, you don't need this, and you'll only be irritated that you got it.

it works but..., December 15, 2009
this product would be better if you could just insert the battery in a holder and plug it into the wall. with this setup you have to plug the camera into the wall. which can cause problems trying to charge up outside of the house. who wants to leave your new flip dangling from a wall socket. poor design from a great camera.

Over heating?, September 23, 2009
Adapter constantly says over heating causing the adapter to take a lot longer to charge. Same thing happens when using the usb on the computer to charge.

FLIP VIDEO POWER ADAPTER, June 7, 2009
I PURCHASED THE FLIP VIDEO POWER ADAPTER TO GO ALONG WITH MY FLIP VIDEO CAMCORDER. I WANTED IT IN CASE I'M NOT NEAR A COMPUTER AND MY FLIP VIDEO CAMCORDER NEEDS MORE CHARGING. THE COMPUTER METHOD IS FASTER BUT THE POWER ADAPTER SUITS MY NEEDS.

works great - no cords to mess with, September 10, 2009
I use this with the rechargeable batts. Love it. Does not get really hot like other plugs might. The flip kinda hangs there and looks like it will fall - so I just prop a book under the flip when using on a wall outlet. Works fine on a power strip without propping. LOVE IT!! I own 2 flips and this plus the rechargeable batteries are awesome!!! The other thing I like is I can throw this in my purse and go - no cords.

GOOD TO HAVE, September 13, 2009
Great to have on a recent trip to Germany. Found out after the fact my laptop (3 prong) wouldn't fit in the adapter/converter (2 prong) we brought, so the FLIP couldn't be charged via the laptop. LUCKILY I had purchased this wall charger and it DID fit in the adapter/converter and I could charge the FLIP successfully. Already it paid for itself. ... Read more

For now, this is the best the US has, January 31, 2009
This micro SDHC card is the best in the US market. Samsung has developed a 32GB one but it is only available in Asia at the time of this writing. With that said, this is a good card. I bought it for my Blackberry Curve 8300. If you are going to use it for a Blackberry, make sure that you have the Blackberry OS 4.5 or later as it will not read the whole 16GB if you do not.

Even though this is a Class 2 card (the 16GB Class 4's, like the 32GB cards, are only available in Asia right now), it reads and writes fairly quickly. The card is fast enough to record and play videos on my Curve, and saving a couple minute video after shooting it literally takes seconds to write.

I have two minor gripes about this card, and they aren't that bad. One is the price. You can get an 8GB card for less than half of the price of this one. However, it is still "new" so that's the penalty for being an early adopter.

The other gripe I have is that with the Samsung reader (see the bundle Amazon sells with this card) will NOT format this card in anything other than FAT32. Now the Curve can't understand NTFS, so for me it's not a big deal, but for someone who may want to use this as take away storage, just be aware of that.

Other than that, I think this card is great. Also please note this card DOES come with an SD adapter. Don't let the Bulk Packaging fool you. If you have an SD card reader, you will not have to go out and buy a separate card reader for this. Save yourself the 5 bucks if you can. I hope this review was helpful.

Works with a Sansa Fuze, March 28, 2009
The card arrived when they said it would. Took it out of the box and stuck it in my MP3 player, the Sansa Fuze (2GB model) and it recognized it immediately and I was able to start putting music on it (didn't need to format it). I put about 10GB of music on it which took roughly 2 hrs to load. After the initial upload of all my music. Adding a new album only took a couple of minutes. After I disconnect the Fuze from the computer it took approx 8-10 minutes to refresh the media library. I have the latest firmware update for the Fuze (maybe older firmware versions are slower - I don't know). The upload speeds didn't bother me because I'm only loading my whole library once and then its only a song/album or two at a time and that's only a few minutes. The card came with a SD adapter - so if you have a SD reader your set. I now have a 18GB MP3 Player!

Beware high failure rate of this card! :(, May 25, 2009
I bought this card in February 2009 and it eventually failed by May 2009. I have of course only anecdotal evidence, but if you search around the Sandisk support forums and other places, you will find a lot of very upset customers complaining of the high failure rate of these Sandisk 16GB SDHC cards after a 2-3 months of use. To compound the problem, Sandisk only offers a 30 day return or refund period warranty on their flash memory cards which is atrocious in my opinion!! Unfortunately, most resellers here on Amazon only have a 30 day return policy as well assuming you have the product still in the original packaging. So overall, you are screwed if and WHEN the card does eventually fail. Thus, I recommend you not rely on this card to store important data like pictures and such. I unfortunately found this out the hard way. It just seems that this card is just not as reliable as advertised, and I am quite disappointed in the lack of at minimum one year manufacture's warranty for these cards by Sandisk. Buyer beware!!

Great at the time but go for at least a class 4 now, July 29, 2009
I bought this six months ago (in January 2009) because it was the only 16GB micro SDHC card available. I needed it to dump as much of my music as I could onto my BlackBerry Bold. It has worked fine for the most part. However, if I were buying such a card today, I would search out at least a class 4 card and probably a class 6, both of which are now available here on Amazon (A-DATA MicroSDHC 16GB Class 6 Turbo With SD Adapter 16GUSDHC6 (Black); Sandisk 16GB Ultra microSDHC CLASS 4 / MobileMate micro Reader (SDSDQY-016G-S11M, Retail Package)).

To the extent that it is a problem, my BlackBerry scans this class 2 card when I do a restart -- and is sluggish during that time -- so because I have almost the entire card filled up, it can take the BB a good five minutes to scan the card because a class 2 card has a slower read speed. That's a good five minutes of unwanted sluggishness after a restart. A faster class 4 or 6 card would reduce that time considerably.

I wish that I had noticed that it's only Class 2 memory, February 2, 2009
I bought this memory for my HTC Touch Pro. I wanted to sync my music with windows media center and backup another USB flash drive. This card should only be used for occasional file transfers. The class 2 card is painfully slow to sync anything. I would have gladly spend more money for a faster Class 6 microSDHC card if I was paying attention at the time of purchase.

Works great in my EVO 4G, July 2, 2010
Bought this to upgrade my EVO 4G Android smartphone and have no complaints, works perfectly. Good value for the money (and now they're even cheaper!). Note when I bought mine it was delivered directly from Amazon (which I wanted as there are counterfeit cards out there).

Roomy and fast enough, September 12, 2009
I learned recently that all is not equal when it comes to SD storage. Some cards are far faster than others, and that can make a big difference in some applications. But this one is just sitting in my phone storing MP3s and files, and speed is never a big deal here, so it's okay that this is a middling-speed card. Plenty roomy for lots of stuff, too, at a good price.

Fake Card, November 10, 2010
I Ordered This SD card thinking it was a great deal almost too good to be true well that's exactly what it was, I got the card and my phone (which does read SDHC cards up to 16 GB) would not read the card. I ended up buying one at Wal-mart and compared the two cards and you could clearly see that the writing was a little different on the 16gd card I'm of the strong belief that it was a counterfeit card, thank fully I got a refund on it but it took Threatening to file a A-Z report to get some action out of the seller, I will Never Buy any electronics from Amazon again this is the second time this type of thing has happened to me last time it was with a Memory Stick DUO for my PSP and that time I didn't get my money back.

FAILED after only a few uses., March 20, 2010
I bought the SanDisk 16 GN Flash Memory card for use with my VHOLDR camera. To say that it took 3 months to fail is misleading. I only actually recorded on it a handful of times, maybe a dozen or so, before it failed. Extremely disappointed.

Great for my Blackberry 8900!, June 9, 2009
Indeed this is a class 2 micro sd (hc) card but for syncing media and storing files on my blackberry it is perfect. Class two (2) cards are generally meant for storage and not a lot of back and forth transfers as they have a high failure rate in that scenario. However, if you are going to sync media once in a while and just update your music/podcasts/audiobooks and pictures then this card is perfect.

It is a bit expensive...but you are getting 16gb and that is a lot of storage...all things considered.

The packaging is in one of those foil bags and it does come with a regular SD adapter to stick into a memory card reader.

I have used it in a Blackberry Bold and now the Blackberry 8900 and it works perfectly. I have not really noticed the speed degradation... The initial sync of all of my media (9gb) took a while...but that would take a while on anything....now with regular updates it is quick and easy and thus Highly Recommended. ... Read more

Good quality product, but not what I wanted., February 17, 2006
The product felt strong, solid, and well put together. The glass was clear with no visible tint or imperfections. Although this and another filter (same type different size) both arrived with smudges on the glass. The smudges were fairly easy to wipe off, but I suspect the items are either not cleaned before packaging, or I received someone's returned item. However, I had to return this item since they DON'T contain any anti-glare/reflective coating on them. When shooting towards a light source (light bulb, tv, sun, etc) a green reflection of the light source would appear on the recorded image. The green reflected image was caused by a reflection bouncing off of my lens's green tinted anti-glare coating which was bounced right back into the camera by this filter. If your lens isn't coated in an anti-glare coating the result will be even worse.
Instead I picked up Quantaray filters from a local Wolf Camera that were coated with the anti-glare. They only cost a little more, and the green reflection is now gone. Make sure you look for a filter with the anti-glare

Camera: Canon 20d, Lenses tested: 18-55, 28-135, 70-300

Far from perfect, December 5, 2005
I bought this filter for my Canon 50mm f/1.8 II Camera Lens. The price was right, and I thought it would be a good way to protect the lens, which this probably does well. And while I am shooting under normal lighting conditions (flash or natural) the filter stays out of the way, but as soon as the lights go down this filter will ruin more photos than I can bear, due to an abundance reflective artifacts. If you take a photo of Christmas lights for example you will see the lights again in a faint green glow on the opposite side of the photo... VERY ANNOYING.

Not multi-coated but does a job, January 16, 2006
The information section for this is a bit messed up and hard to read, but you'll see that other versions are available for this UV filter.

This one is not a multi-coated version at this price but does work to reduce the danger of damage to your camera lens.

Here is what they are TRYING to tell us about the various versions in the description area:

UV filter- Standard UV Most popular protection filter
UV MC - Multi coated for extra flare protection
UV Warm - Combines UV with Tiffen's '812' warming filter
Haze 1 - Absorbs 75% of UV light
Haze 2 -Absorbs 100% of UV light
Haze 15-Absorbs 81% of UV light
Haze 16-Absorbs 86.5% of UV light
Haze 17 - Absorbs almost all UV light
UV Wide Angle Thin - UV filter for use with wide angle lenses.

fdl, October 25, 2000
Any photographer who has the money to purchase a lens with a professional 77mm filter size can afford better than this uncoated Tiffen filter. I'm skeptical by nature, so I wanted to see for myself whether coated glass was really necessary. I purchased this Tiffen filter and used it on two different lenses and found that in almost every single photograph in which there was a light source, I found two smaller ghost images of the light source elsewhere in the photo. This uncoated glass really knows how to make lens flare POP (even if it's not the lens that's flaring...)! I sent mine back, with the biggest loss being my time and Christmas photographs of family that would have otherwise been very nice.

What made the two little ghosts appear on the Tiffen? Light as faint as Christmas tree lights, table lamps, incandescent overhead bulbs, etc. You name it, basically.

How do I know this was due to the UV filter and not my lenses? When I saw some pretty nasty flare, I just unscrewed the Tiffen filter and voila, my flare disappeared.

Le flare est morte. Vive le flare!

Seriously, spend just a bit more and get a good, coated (on both sides) filter; picky people like myself will gladly spend a little more and get a coated filter by Hoya or B+W, among others. The Tiffen is fine if you only shoot in the shade without any relatively bright lights; otherwise, my advice is to look elsewhere.

Internal Reflections, June 16, 2006
This filter is fine for normal shooting, but if you do low-light work, beware; you will see bad internal reflections on night shots, and will need to remove the filter.

Quality Lens Protection and Decent UV Filtration for Your SLR Camera, January 23, 2008
You spent a lot of money for your SLR or digital SLR camera, and then you plunked down another large chunk of cash for a quality lens. Do you really want to blow another heavy chunk of change for a basic, thread on UV filter? Well, I would normally advise that you don't skimp on quality when it comes to filters. After all, would you pay a premium price for a high performance automobile, only to fill it with watered down fuel? I should nope not! So is it such a bright idea to buy such a low cost UV filter for your high-end SLR lens? Well, maybe it is if you are considering the Tiffen 77mm UV Protection Filter.

This filter does NOT offer the highest level of UV filtration, but it is rather sufficient for most conditions, and the build quality and materials used in this filter are very good. For most digital SLR users, a UV filter is a must have for protecting your lens optics, and it helps to clear up the hazy and washed out look in many of your outdoor photos. This filter has proven to clean up many of my digital photographs, and I have found almost no internal reflection artifacts. Notice I said ALMOST no internal reflection. I leave my UV filters on all of my lenses almost all of the time, and this filter has produced some minor reflection when shooting indoor photos with my Sigma 10-20mm ultra-wide angle lens. This seems to only happen when shooting in dim lighting conditions, and when aiming the lens in the direction of a strong light source, such as a table lamp. Since my Canon EOS 40D has a "Live View" feature that lets me see what the picture is going to look like (displayed on the 3" LCD), I can see the reflection artifacts before I shoot the picture, and therefore have found ways to reframe my shots to avoid the reflections. However, I recommend that you simply remove the UV filter when shooting in these conditions.

As I said before, I typically do not recommend buying low cost filters for your high quality lenses, but I prefer to invest my money on creative filters and not pour too much into a filter that is primarily used to simply protect the front of the lens. Many manufacturers, including Tiffen, offer higher quality UV/Haze filters for SLR lenses, and you may wish to spend the extra money if you are looking for deeper UV removal from your pictures. However, if you are looking for great lens protection and a decent level of UV filtration for a modest investment, you honestly can't go wrong with this filter. Just remember to remove the filter, or frame your shots carefully when shooting in situations where direct light reflection may be an issue.

Quality = **** (4)
UV Filtration = **** (4)
Value = ***** (5)

WARNING: CHEAP GLASS, March 14, 2005
This UV filter does it job to protect the lens well. The build is solid (metal construction). The glass is also descent quality.

About the performance, it absorbs some UV light. The UV light absorbtion is hardly noticeable, probably the sky 1-A and the haze filter version will absorb more UV light than this lens which is fine for me.

Now, about the one problem which is the internal reflection. I've heard many people say that it mostly happens during night or low light shooting. I found out that it is not caused directly by the low light/night situation. The internal reflection will appear when there is a strong/bright source of light in comparison to the overall exposure (the surrounding environment). To put it in example (which hopefully is easier to understand), when you take a picture of a lamp during nightime and the light is much brighter than the surrounding area then you will see the internal reflection. as you move the position of the light to be closer to the sides/corner of the picture (and not in the center of the picture), the internal reflection reduces and finally dissapear (if you move the light far enough from the center). And if the light isn't too bright/contrast compare to the surrounding environment then there will be no internal reflection. but of course most of the time, a lamp at nightime is often very bright. But the point that I'm trying to make is that the internal reflection doesn't happen all the time during low light or night time.

Additionally, the internal reflection isn't only happening at night. it can also happen in the afternoon if you are taking a picture of a sun for example. basically same rule as above, on how bright is the light source compared to the surrounding area, and as you move the sun from the center of the photo and near the side the internal reflection will move to the side/dissapear (also depending the angle). But the best way is just to remove the filter during these situations.

Hope this explanation helps you to reduce the occurence of internal reflection by identifying correctly when the internal reflection will occur and then remove the filter during those situation (which is not hard to do).

I'm actually not a fan of lens filter (any filter) as I think it will only degrade picture quality as we added another layer between the sensor and object, but I decided to use them anyway for all my lens. And I would recommend everyone to get one of this filter if you don't have any filter for your lens yet.

I use this filter on my 50mm f/1.8D lens and on my 18-55mm lens.

If you take a photo of Christmas lights for example you will see the lights again in a faint green glow on the opposite side of the photo... VERY ANNOYING.

Not multi-coated but does a job, January 16, 2006
The information section for this is a bit messed up and hard to read, but you'll see that other versions are available for this UV filter.

This one is not a multi-coated version at this price but does work to reduce the danger of damage to your camera lens.

Here is what they are TRYING to tell us about the various versions in the description area:

UV filter- Standard UV Most popular protection filter
UV MC - Multi coated for extra flare protection
UV Warm - Combines UV with Tiffen's '812' warming filter
Haze 1 - Absorbs 75% of UV light
Haze 2 -Absorbs 100% of UV light
Haze 15-Absorbs 81% of UV light
Haze 16-Absorbs 86.5% of UV light
Haze 17 - Absorbs almost all UV light
UV Wide Angle Thin - UV filter for use with wide angle lenses.

fdl, October 25, 2000
I use a UV filter on my lens to protect it because unlike others it has the least effect on the amount of light passing through it and does not affect color. I use it indoors and out with both black and white and color films. The only time it is off of my lense is when I want to affect color or contrast by using a special filter. It reduces haze to improve the clarity of outdoor pictures. Tiffen filters are well constructed.

Two little ghosts for every light source, January 7, 2008
Any photographer who has the money to purchase a lens with a professional 77mm filter size can afford better than this uncoated Tiffen filter. I'm skeptical by nature, so I wanted to see for myself whether coated glass was really necessary. I purchased this Tiffen filter and used it on two different lenses and found that in almost every single photograph in which there was a light source, I found two smaller ghost images of the light source elsewhere in the photo. This uncoated glass really knows how to make lens flare POP (even if it's not the lens that's flaring...)! I sent mine back, with the biggest loss being my time and Christmas photographs of family that would have otherwise been very nice.

What made the two little ghosts appear on the Tiffen? Light as faint as Christmas tree lights, table lamps, incandescent overhead bulbs, etc. You name it, basically.

How do I know this was due to the UV filter and not my lenses? When I saw some pretty nasty flare, I just unscrewed the Tiffen filter and voila, my flare disappeared.

Le flare est morte. Vive le flare!

Seriously, spend just a bit more and get a good, coated (on both sides) filter; picky people like myself will gladly spend a little more and get a coated filter by Hoya or B+W, among others. The Tiffen is fine if you only shoot in the shade without any relatively bright lights; otherwise, my advice is to look elsewhere.

Internal Reflections, June 16, 2006
This filter is fine for normal shooting, but if you do low-light work, beware; you will see bad internal reflections on night shots, and will need to remove the filter.

Quality Lens Protection and Decent UV Filtration for Your SLR Camera, January 23, 2008
You spent a lot of money for your SLR or digital SLR camera, and then you plunked down another large chunk of cash for a quality lens. Do you really want to blow another heavy chunk of change for a basic, thread on UV filter? Well, I would normally advise that you don't skimp on quality when it comes to filters. After all, would you pay a premium price for a high performance automobile, only to fill it with watered down fuel? I should nope not! So is it such a bright idea to buy such a low cost UV filter for your high-end SLR lens? Well, maybe it is if you are considering the Tiffen 77mm UV Protection Filter.

This filter does NOT offer the highest level of UV filtration, but it is rather sufficient for most conditions, and the build quality and materials used in this filter are very good. For most digital SLR users, a UV filter is a must have for protecting your lens optics, and it helps to clear up the hazy and washed out look in many of your outdoor photos. This filter has proven to clean up many of my digital photographs, and I have found almost no internal reflection artifacts. Notice I said ALMOST no internal reflection. I leave my UV filters on all of my lenses almost all of the time, and this filter has produced some minor reflection when shooting indoor photos with my Sigma 10-20mm ultra-wide angle lens. This seems to only happen when shooting in dim lighting conditions, and when aiming the lens in the direction of a strong light source, such as a table lamp. Since my Canon EOS 40D has a "Live View" feature that lets me see what the picture is going to look like (displayed on the 3" LCD), I can see the reflection artifacts before I shoot the picture, and therefore have found ways to reframe my shots to avoid the reflections. However, I recommend that you simply remove the UV filter when shooting in these conditions.

As I said before, I typically do not recommend buying low cost filters for your high quality lenses, but I prefer to invest my money on creative filters and not pour too much into a filter that is primarily used to simply protect the front of the lens. Many manufacturers, including Tiffen, offer higher quality UV/Haze filters for SLR lenses, and you may wish to spend the extra money if you are looking for deeper UV removal from your pictures. However, if you are looking for great lens protection and a decent level of UV filtration for a modest investment, you honestly can't go wrong with this filter. Just remember to remove the filter, or frame your shots carefully when shooting in situations where direct light reflection may be an issue.

Quality = **** (4)
UV Filtration = **** (4)
Value = ***** (5)

WARNING: CHEAP GLASS, March 14, 2005
Tiffen filters use cheap, optically low-grade "GREEN" glass. Get a Hoya UV filter. It's only $6 more.

Great value for inexpensive lenses, August 1, 2008
At a range between $7 and $10, this is one of the best values and investments out there. What is it actually used for? A UV filter has two primary purposes: to filter out unwanted ultra-violet light and to protect the lens. For most general photography applications, you will not notice the difference in UV light. Only when you have intense sunlight at a specific angle will you start to notice the UV light. It will not alter your photos and their lighting negatively, so you can pretty much leave this filter on all the time. This filter doesn't do that great of a job in actually filtering out harsh light at the ultra-violet spectrum, but if you're an amateur photographer, you won't need that function. If you do encounter a lot of harsh UV light (you live out in the desert or in Alaska), then you should consider a different filter. As an advanced but non-professional photographer who averages 500 photos indoors and outdoors per week, I have not yet encountered any harsh UV light that this filter cannot block.

I use this on my Canon 18-55mm f/3.5-5.6 lens, and I pretty much never take it off. This filter will protect your lens from scratches to the glass. When you get smudges (which you will) on this filter, you just wipe the filter or remove it and clean it. It's much easier to clean this filter than the glass on the lens. But the most important part is that this filter serves as insurance for your lens. If something comes flying at your lens, you have a choice of replacing a $7 filter or a $150 lens. It's a no-brainer!

Now, this filter is useful for either the amateur photographer or the advanced photographer who has a relatively cheap lens (a $150 lens is considered CHEAP compared to $950 for the Canon 17-55mm f/2.8 IS). If you own a more expensive lens, you'd want to go with a better filter, such as one from Hoya or B+W. But if you own the Canon Canon 17-55mm f/2.8 IS or an L lens, you know that already.

All in all, I gave this filter 5 stars because of its great value. If it costs $20, I would have reduced it to 4 stars. Considering its use, you cannot beat this product.

Surprisingly good (except in one situation, which it will create internal reflection), October 8, 2006
This UV filter does it job to protect the lens well. The build is solid (metal construction). The glass is also descent quality.

About the performance, it absorbs some UV light. The UV light absorbtion is hardly noticeable, probably the sky 1-A and the haze filter version will absorb more UV light than this lens which is fine for me.

Now, about the one problem which is the internal reflection. I've heard many people say that it mostly happens during night or low light shooting. I found out that it is not caused directly by the low light/night situation. The internal reflection will appear when there is a strong/bright source of light in comparison to the overall exposure (the surrounding environment). To put it in example (which hopefully is easier to understand), when you take a picture of a lamp during nightime and the light is much brighter than the surrounding area then you will see the internal reflection. as you move the position of the light to be closer to the sides/corner of the picture (and not in the center of the picture), the internal reflection reduces and finally dissapear (if you move the light far enough from the center). And if the light isn't too bright/contrast compare to the surrounding environment then there will be no internal reflection. but of course most of the time, a lamp at nightime is often very bright. But the point that I'm trying to make is that the internal reflection doesn't happen all the time during low light or night time.

Additionally, the internal reflection isn't only happening at night. it can also happen in the afternoon if you are taking a picture of a sun for example. basically same rule as above, on how bright is the light source compared to the surrounding area, and as you move the sun from the center of the photo and near the side the internal reflection will move to the side/dissapear (also depending the angle). But the best way is just to remove the filter during these situations.

Hope this explanation helps you to reduce the occurence of internal reflection by identifying correctly when the internal reflection will occur and then remove the filter during those situation (which is not hard to do).

I'm actually not a fan of lens filter (any filter) as I think it will only degrade picture quality as we added another layer between the sensor and object, but I decided to use them anyway for all my lens. And I would recommend everyone to get one of this filter if you don't have any filter for your lens yet.

I use this filter on my 50mm f/1.8D lens and on my 18-55mm lens.

Not All Class 10 Cards are Equal, April 11, 2010
UPDATE 9-10 I own 4 of these cards now. I have more of these than any other card I own because the are a very good value for capacity/price/and speed. My initial dissapointment over the lack of super high speed is outweighed by the reality that this card is an exceptional value.

Origional Review:
I purchased this card making the assumption that all class 10 cards had the same read and write speed. This was a poor assumption on my part.

The product photo on Amazon does not have the card's speed printed on it. The card that was shipped shows the front of the card printed with "20MB/s" which is the cards read speed. The cards write speed is only 16MB/s.

I own a SanDisk Extreme III class 10 card that has (up to) 30MB/s read and write speed. My Nikon D-90 that can take advantage of the SanDisk cards speed. The difference is the SanDisk card can capture 100 photos at fine resolution in 24 seconds. The Transcend card captures 66 photos in the same time/resolution.

I reality very few people will ever have the need to drill off 100 photos in 24 seconds, but I can't stand to loose a good shot because the camera is slow while writing to the card and I can't fire the shutter. You can hear this happen at about 4.5 seconds in the video review. This does not happen with the SanDisk class 10 30MB/s card.

A lot can happen in a fraction of a second that can make a shot good or bad and the having ability to fire a lot of shots in rapid succession is important to me.

If you own an SLR that is capable of rapid fire, high-resolution photography you may want to consider the SanDisk Extreme III 30 MB/s card.

If you own a compact digital camera, this card will exceed the capabilities of all of them. For compact cameras the card isn't usually the slowest part of the data write process, it's the camera.

This card is reasonably priced for a class 10 card. Just know what you are getting, what your needs may be, and what else is available. I own other Transcend cards and they have always worked properly without any issues.

The video that I attached shows this card with the same 24 seconds that I gave the SanDisk Card.

Sandisk SDSDX3-008G-E31 8GB Extreme III SD Card 30MB/s (RETAIL PACKAGE)

Fast!, April 8, 2010
I purchased this for use with my new Canon T2i. I use it primarily for shooting full resolution 1080p video, although I shoot stills as well.

The camera choked on the class 4 chip that I originally purchased, but with this one, it is amazing. I can shoot rapidfire 18 megapixel stills (I've tested it up to 30+ shots in a row), and there is no lag. I've never had an error when shooting hi-def video.

Highly recommended! I'm buying another one.

Fast, fast, fast!, March 15, 2010
I bought this card for my Canon T1i. The card I had been using before ordering this one was a Kingston Class 6 micro sd card and it worked well enough for the type of shooting I did. Class 6 was the card speed that Canon recommended when I bought my T1i (Class 10 cards were not yet available) and it seemed fast enough for the way I used my camera - isolated single photos taken at Medium (8 MP) or Large (15 MP) jpg settings and 1280 x 720 video. And while I ocassionally took continuous photos, I had never much exceeded 5-10 photos in a row and had never run into a problem with my Class 6 card.

When I first saw the Class 10 cards I did some experiments with my camera. How many continuous Large photos could I take before the camera slowed down? It turned out to be about 30. And how many RAW photos could I take before the camera slowed down? It turned out to be about 9. SInce I did not generally take any photos in RAW and never needed more than about 10 continuous photos at Large, the Class 6 card seemed more than sufficient for my needs. But I wondered about the speed of the Class 10 cards enough that I finally bought one.

It turns out that the Class 10 card is sufficiently fast that there does not seem to be a reasonable upper limit on single Large photos. I have taken 60 on continuous without an issue. And although I still cannot take more than 9 RAW photos on continuous with the Class 10 card, when I am finished taking those photos the camera no longer displays a Wait - writing pictures screen. The RAW photos get written from the built-in memory to the card so quickly that the camera does not need to display the Wait screen.

So this card is fast! Given the way I take photos this purchase was unnecessary, but still I am glad I bought it. I know I will not run into a situation where speed is an issue with this card.

Transcend vs Sandisk of equal price, July 31, 2010
OK. this card was around $47 for a class 10 16gb. The other card i bought was a Sandisk class 10 8gb for the around same price. I did a 10 sec stop watch test on both cards with my Rebel T1i on raw and the Sandisk was only faster by 1 shot in a 10 sec burst. to me it seems trivial to pay 47 bucks for a Sandisk 8gig when you can get 16 gigs for the same price. yes i know, the Sandisk is good for arctic and desert temperatures... but i live in western NY... not Antarctica or the Sahara. If your looking for a good card, with more gigs for your buck, the Transcend is well worth it.

Slower than slow on Pentax K-x, April 25, 2010
I bought this for my pentax K-x but it would randomly corrupt images. Also, it was slower than my 3+ year old SandDisk Ultra 1GB card. I was told by the seller (Thememstore) that others with the k-x have had the same problems. So apparently it must have something to do with the class 10 part, because since I returned this card I bought a SandDisk Extreme III 4GB Class 6 and it works far better.

Would I recommend this card? Yes, but only to someone who knows that class 10 will work in their camera. I don't fault the card as I think the problem is with the K-x.

DESTROYS DATA -- after working fine for just long enough to fool you!, November 6, 2010
SUMMARY:


DO NOT BUY THIS CARD UNLESS YOU WANT TO PLAY RUSSIAN ROULETTE WITH YOUR DATA. Card worked fine when I bought it, but malfunctioned within the first 400 photos -- malfunctioned so badly that some very technical tools were needed to recover anything at all, and some photos were still permanently lost. Recovering the data requires the attention of a serious data recovery expert or someone with substantial technical knowledge and lots of time.


DETAILS:

I made the mistake buying this card for my camera right before a long trip overseas. It worked fine on the first few dozen shots. I didn't see any improvement in speed over my trusty 1.5-year-old Transcend 8GB Class-6 card, but that was most likely because the camera itself (Canon EOS Rebel 1000D/XSi) could not write images any faster than that (full-size JPEG, continuous shutter mode, roughly did ~2.5-3 images/second on both cards, with no slowdown after the first few shots).

200 shots or so into using this card, I get a sudden mysterious message from the camera when I try to take a new shot -- Card Format Invalid (never saw it in the previous 1.5 years on this camera with 3 other SDHC cards). I look around for a bit, and discover that turning the camera off, pulling the card out and putting it back in is enough to clear the error message, and the previous photos are still visible.

I then make the mistake of assuming the problem is just that -- needing to "reboot" the camera when the card is acting stupid, and nothing else. Over the next 200 or so shots, this problem comes up every 50 shots or so. Then, after yet another "reboot", I notice that the camera's playback function is only showing the last 30 photos!!! Yet it shows that there's only 5.7G of space left on the camera -- the other 2G+ _should_ be taken up by the photos I've shot thus far, but the playback doesn't show them.

And this happens in the middle of a trek through the Peruvian Andes, several days' walk/horse ride from the first village with electricity, let alone a computer (with lots of once-in-a-lifetime shots on the camera). I pull this card out immediately, plug in my backup card, and wait until coming back to civilization to take a look at the card. Sure enough, the card is severely corrupted -- the directory listing is showing a bunch of folders with weird-character names, and only the last ~30 photos are visible from the computer, too!


RECOVERY SUGGESTIONS:

Hopefully you'll read this before buying and will not buy this piece of junk card. If you had the misfortune of running into the same problem and losing your data, read on.

I have now had time to examine what was left on the card, using tools that are not easily usable to people without substantial technical training. I've managed to recover over 90% of my photos, but this was NOT easy, and I suspect that even some shops specializing in data recovery from failed disks may not know how to get your data back -- this is NOT as simple as just undeleting a file!

Non-technical instructions:

1. As soon as you see the FIRST error involving the card format, turn off the camera, pull out the card, and copy all of your photos to a different device (computer/harddrive/whatnot). The earlier you stop using this card, the safer your photos will be.

2. As soon as the first problem happens, move the little plastic slider on the side of the card to the "Lock" position -- this will prevent anything else from being written on the card, which lowers the risk of what's left of your photos being overwritten.

3. If you see directories (aka folders) with weird names when you plug this card into a computer -- or see a huge number of photos missing when you look at them on the camera, take the card out IMMEDIATELY, and take the card to a data recovery shop or a technical expert willing to look at the card in depth. Give them a printout of the explanation below.


Technical details:

At least in my case, the filesystem was indeed somehow damaged, perhaps by the camera deciding to write over the location of the root directory somehow. I took a full disk image of the card, and operated on the disk image only (there were no read errors when making the image, FWIW). Somehow I was lucky enough to have the original _subdirectories_ \DCIM and \DCIM\100CANON survive on the card intact even though the root directory structure now pointed to a different, new, place on the filesystem as \DCIM.

I found the location of the old 100CANON directory on the filesystem by searching for one of the filenames I knew would exist in the old directory, like IMG_7000, across the whole disk image.

I then edited the filesystem (yea, with a hex editor!) to have the new \DCIM directory point to the old 100CANON subdirectory. See the Wikipedia article on FAT32 for a reasonably easy reference on how to find the 4 bytes that need to be edited, and how to calculate the correct updated value.

Mounting the edited disk image (with Linux's 'mount -t loop'), the directory was intact, and all but about 5% of the photos were completely intact as well -- the remainder must have been overwritten after the directory structure got corrupted. Depending on how long it takes the user to notice a problem, of course, much more damage could easily happen to the original data.

Here's one easy hack to see how much you can hope to recover, if you're recovering camera data. The same trick may be useful for locating the JPEGs if the original image-containing directory is no longer intact (good luck with recovery then! I thankfully didn't have to do this). Take any image produced by the same camera, look at its JFIF headers. My camera leaves the string "Canon EOS DIGITAL REBEL XS" in two places in every JPEG it creates, early on in the JFIF header. Search for that string across the whole filesystem. If there's, say, 500 hits, that means you can hope for [easy] recovery of at most 250 photos -- any photo that is missing the JFIF headers will be missing the first chunk of the file, and will make it very hard both to find _and_ to reconstruct the remaining data, if any, into a usable JPEG (I have not tried to do this, at least, and it seems very hard).

Transcend Vs. Sandisk on Panasonic LX5, November 12, 2010
I will be writing this review for both SanDisk Extreme SDHC class 10 8gb and Transcend SDHC class 10 16gb.

I bought SanDisk class 10 and Transcend class 10 for my new Panasonic LX5. I got both card because no one really did a comparison with a compact camera and I was just going crazy trying to see if there is any big difference between the 2 cards.

SanDisk Extreme package box indicated it's water proof, x-ray proof, shock proof, temperature proof. I am not ready to spend $50 to see if it really stand up to it's words. And I don't think normal people would go through the extreme condition in taking pictures or videos.

Cut the story short, I really want to see if there is any difference in writing performance between the 2 cards in a compact camera. There is a continuous burst mode in LX5 and the manual indicated it is only limited by the condition of picture environment and performance of the SD card. Within the mode there are 2 different settings:1) speed priority or 2) picture/quality priority. The shutter speed is much faster with speed priority compare to picture priority.

I first formatted both cards out of box then put each card in series of test(3 rounds each setting for each card) shooting at the same object under same lighting condition. The results:
Speed Priority:
SanDisk Class 10 8gb
22-33 shots before camera stopped to allow the card to catch up with writing.

Transcend Class 10 16gb
22-24 shots before camera stopped to allow the card to catch up with writing.

Picture priority
SanDisk Class 10 8gb
34-46 shots before camera stopped

Transcend Class 10 16gb
27-33 shots before camera stopped


It seems that at a higher shutter speed, both cards performed very similar under the same shooting condition. But at a slower shutter speed the SanDisk definitely out perform Transcend. I hope this little experiment satisfied anyone with curiosity like me. Transcend definitely is a bargain with 16gb and almost half of the price compare to SanDisk. But I am going to use SanDisk Extreme as my primary card and Transcend as backup or on a second camera to ensure i would not miss any shots.

Depend on what you will use it for ..., October 13, 2010
The "C10" is for "minimum sustaining speed" of 10mbps. The sustaining speed is critical if you're using for HD camcorder. There is other brand card that is also c10 but it costs more (2x) for its print of 30mbps on the card. It leads consumers into thinking that the higher price is worth for the 30mbps. However, the 30mbps is the "burst" speed. Burst speed is critical for HD camera and for doing copies. I have a HD camcorder and I'm very satisfied with this card after many hours for recording. I bought this card to do 100% of recording so it is the right price. I would buy the other high price brand card of 30mbps if I will do a lot of picture taking. The bottom line is to buy for the purpose of your usage.

Not very fast, April 14, 2010
On my Panasonic GF1, it's the same speed as a Class 6 Transcend card and much slower than a Class 10 SanDisk Extreme. Buy the Transcend Class 6 if you want to save money or the SanDisk if you wan speed, but skip this one.

I bought this card for my Canon T1i. The card I had been using before ordering this one was a Kingston Class 6 micro sd card and it worked well enough for the type of shooting I did. Class 6 was the card speed that Canon recommended when I bought my T1i (Class 10 cards were not yet available) and it seemed fast enough for the way I used my camera - isolated single photos taken at Medium (8 MP) or Large (15 MP) jpg settings and 1280 x 720 video. And while I ocassionally took continuous photos, I had never much exceeded 5-10 photos in a row and had never run into a problem with my Class 6 card.

When I first saw the Class 10 cards I did some experiments with my camera. How many continuous Large photos could I take before the camera slowed down? It turned out to be about 30. And how many RAW photos could I take before the camera slowed down? It turned out to be about 9. SInce I did not generally take any photos in RAW and never needed more than about 10 continuous photos at Large, the Class 6 card seemed more than sufficient for my needs. But I wondered about the speed of the Class 10 cards enough that I finally bought one.

It turns out that the Class 10 card is sufficiently fast that there does not seem to be a reasonable upper limit on single Large photos. I have taken 60 on continuous without an issue. And although I still cannot take more than 9 RAW photos on continuous with the Class 10 card, when I am finished taking those photos the camera no longer displays a Wait - writing pictures screen. The RAW photos get written from the built-in memory to the card so quickly that the camera does not need to display the Wait screen.

So this card is fast! Given the way I take photos this purchase was unnecessary, but still I am glad I bought it. I know I will not run into a situation where speed is an issue with this card.

Transcend vs Sandisk of equal price, July 31, 2010
OK. this card was around $47 for a class 10 16gb. The other card i bought was a Sandisk class 10 8gb for the around same price. I did a 10 sec stop watch test on both cards with my Rebel T1i on raw and the Sandisk was only faster by 1 shot in a 10 sec burst. to me it seems trivial to pay 47 bucks for a Sandisk 8gig when you can get 16 gigs for the same price. yes i know, the Sandisk is good for arctic and desert temperatures... but i live in western NY... not Antarctica or the Sahara. If your looking for a good card, with more gigs for your buck, the Transcend is well worth it.

Slower than slow on Pentax K-x, April 25, 2010
I bought this for my pentax K-x but it would randomly corrupt images. Also, it was slower than my 3+ year old SandDisk Ultra 1GB card. I was told by the seller (Thememstore) that others with the k-x have had the same problems. So apparently it must have something to do with the class 10 part, because since I returned this card I bought a SandDisk Extreme III 4GB Class 6 and it works far better.

Would I recommend this card? Yes, but only to someone who knows that class 10 will work in their camera. I don't fault the card as I think the problem is with the K-x.

DESTROYS DATA -- after working fine for just long enough to fool you!, November 6, 2010
SUMMARY:


DO NOT BUY THIS CARD UNLESS YOU WANT TO PLAY RUSSIAN ROULETTE WITH YOUR DATA. Card worked fine when I bought it, but malfunctioned within the first 400 photos -- malfunctioned so badly that some very technical tools were needed to recover anything at all, and some photos were still permanently lost. Recovering the data requires the attention of a serious data recovery expert or someone with substantial technical knowledge and lots of time.


DETAILS:

I made the mistake buying this card for my camera right before a long trip overseas. It worked fine on the first few dozen shots. I didn't see any improvement in speed over my trusty 1.5-year-old Transcend 8GB Class-6 card, but that was most likely because the camera itself (Canon EOS Rebel 1000D/XSi) could not write images any faster than that (full-size JPEG, continuous shutter mode, roughly did ~2.5-3 images/second on both cards, with no slowdown after the first few shots).

200 shots or so into using this card, I get a sudden mysterious message from the camera when I try to take a new shot -- Card Format Invalid (never saw it in the previous 1.5 years on this camera with 3 other SDHC cards). I look around for a bit, and discover that turning the camera off, pulling the card out and putting it back in is enough to clear the error message, and the previous photos are still visible.

I then make the mistake of assuming the problem is just that -- needing to "reboot" the camera when the card is acting stupid, and nothing else. Over the next 200 or so shots, this problem comes up every 50 shots or so. Then, after yet another "reboot", I notice that the camera's playback function is only showing the last 30 photos!!! Yet it shows that there's only 5.7G of space left on the camera -- the other 2G+ _should_ be taken up by the photos I've shot thus far, but the playback doesn't show them.

And this happens in the middle of a trek through the Peruvian Andes, several days' walk/horse ride from the first village with electricity, let alone a computer (with lots of once-in-a-lifetime shots on the camera). I pull this card out immediately, plug in my backup card, and wait until coming back to civilization to take a look at the card. Sure enough, the card is severely corrupted -- the directory listing is showing a bunch of folders with weird-character names, and only the last ~30 photos are visible from the computer, too!


RECOVERY SUGGESTIONS:

Hopefully you'll read this before buying and will not buy this piece of junk card. If you had the misfortune of running into the same problem and losing your data, read on.

I have now had time to examine what was left on the card, using tools that are not easily usable to people without substantial technical training. I've managed to recover over 90% of my photos, but this was NOT easy, and I suspect that even some shops specializing in data recovery from failed disks may not know how to get your data back -- this is NOT as simple as just undeleting a file!

Non-technical instructions:

1. As soon as you see the FIRST error involving the card format, turn off the camera, pull out the card, and copy all of your photos to a different device (computer/harddrive/whatnot). The earlier you stop using this card, the safer your photos will be.

2. As soon as the first problem happens, move the little plastic slider on the side of the card to the "Lock" position -- this will prevent anything else from being written on the card, which lowers the risk of what's left of your photos being overwritten.

3. If you see directories (aka folders) with weird names when you plug this card into a computer -- or see a huge number of photos missing when you look at them on the camera, take the card out IMMEDIATELY, and take the card to a data recovery shop or a technical expert willing to look at the card in depth. Give them a printout of the explanation below.


Technical details:

At least in my case, the filesystem was indeed somehow damaged, perhaps by the camera deciding to write over the location of the root directory somehow. I took a full disk image of the card, and operated on the disk image only (there were no read errors when making the image, FWIW). Somehow I was lucky enough to have the original _subdirectories_ \DCIM and \DCIM\100CANON survive on the card intact even though the root directory structure now pointed to a different, new, place on the filesystem as \DCIM.

I found the location of the old 100CANON directory on the filesystem by searching for one of the filenames I knew would exist in the old directory, like IMG_7000, across the whole disk image.

I then edited the filesystem (yea, with a hex editor!) to have the new \DCIM directory point to the old 100CANON subdirectory. See the Wikipedia article on FAT32 for a reasonably easy reference on how to find the 4 bytes that need to be edited, and how to calculate the correct updated value.

Mounting the edited disk image (with Linux's 'mount -t loop'), the directory was intact, and all but about 5% of the photos were completely intact as well -- the remainder must have been overwritten after the directory structure got corrupted. Depending on how long it takes the user to notice a problem, of course, much more damage could easily happen to the original data.

Here's one easy hack to see how much you can hope to recover, if you're recovering camera data. The same trick may be useful for locating the JPEGs if the original image-containing directory is no longer intact (good luck with recovery then! I thankfully didn't have to do this). Take any image produced by the same camera, look at its JFIF headers. My camera leaves the string "Canon EOS DIGITAL REBEL XS" in two places in every JPEG it creates, early on in the JFIF header. Search for that string across the whole filesystem. If there's, say, 500 hits, that means you can hope for [easy] recovery of at most 250 photos -- any photo that is missing the JFIF headers will be missing the first chunk of the file, and will make it very hard both to find _and_ to reconstruct the remaining data, if any, into a usable JPEG (I have not tried to do this, at least, and it seems very hard).

Transcend Vs. Sandisk on Panasonic LX5, November 12, 2010
I will be writing this review for both SanDisk Extreme SDHC class 10 8gb and Transcend SDHC class 10 16gb.

I bought SanDisk class 10 and Transcend class 10 for my new Panasonic LX5. I got both card because no one really did a comparison with a compact camera and I was just going crazy trying to see if there is any big difference between the 2 cards.

SanDisk Extreme package box indicated it's water proof, x-ray proof, shock proof, temperature proof. I am not ready to spend $50 to see if it really stand up to it's words. And I don't think normal people would go through the extreme condition in taking pictures or videos.

Cut the story short, I really want to see if there is any difference in writing performance between the 2 cards in a compact camera. There is a continuous burst mode in LX5 and the manual indicated it is only limited by the condition of picture environment and performance of the SD card. Within the mode there are 2 different settings:1) speed priority or 2) picture/quality priority. The shutter speed is much faster with speed priority compare to picture priority.

I first formatted both cards out of box then put each card in series of test(3 rounds each setting for each card) shooting at the same object under same lighting condition. The results:
Speed Priority:
SanDisk Class 10 8gb
22-33 shots before camera stopped to allow the card to catch up with writing.

Transcend Class 10 16gb
22-24 shots before camera stopped to allow the card to catch up with writing.

Picture priority
SanDisk Class 10 8gb
34-46 shots before camera stopped

Transcend Class 10 16gb
27-33 shots before camera stopped


It seems that at a higher shutter speed, both cards performed very similar under the same shooting condition. But at a slower shutter speed the SanDisk definitely out perform Transcend. I hope this little experiment satisfied anyone with curiosity like me. Transcend definitely is a bargain with 16gb and almost half of the price compare to SanDisk. But I am going to use SanDisk Extreme as my primary card and Transcend as backup or on a second camera to ensure i would not miss any shots.

Depend on what you will use it for ..., October 13, 2010
The "C10" is for "minimum sustaining speed" of 10mbps. The sustaining speed is critical if you're using for HD camcorder. There is other brand card that is also c10 but it costs more (2x) for its print of 30mbps on the card. It leads consumers into thinking that the higher price is worth for the 30mbps. However, the 30mbps is the "burst" speed. Burst speed is critical for HD camera and for doing copies. I have a HD camcorder and I'm very satisfied with this card after many hours for recording. I bought this card to do 100% of recording so it is the right price. I would buy the other high price brand card of 30mbps if I will do a lot of picture taking. The bottom line is to buy for the purpose of your usage.

Not very fast, April 14, 2010
On my Panasonic GF1, it's the same speed as a Class 6 Transcend card and much slower than a Class 10 SanDisk Extreme. Buy the Transcend Class 6 if you want to save money or the SanDisk if you wan speed, but skip this one.

Not All Class 10 Cards are Equal, April 11, 2010
UPDATE 9-10 I own 4 of these cards now. I have more of these than any other card I own because the are a very good value for capacity/price/and speed. My initial dissapointment over the lack of super high speed is outweighed by the reality that this card is an exceptional value.

Origional Review:
I purchased this card making the assumption that all class 10 cards had the same read and write speed. This was a poor assumption on my part.

The product photo on Amazon does not have the card's speed printed on it. The card that was shipped shows the front of the card printed with "20MB/s" which is the cards read speed. The cards write speed is only 16MB/s.

I own a SanDisk Extreme III class 10 card that has (up to) 30MB/s read and write speed. My Nikon D-90 that can take advantage of the SanDisk cards speed. The difference is the SanDisk card can capture 100 photos at fine resolution in 24 seconds. The Transcend card captures 66 photos in the same time/resolution.

I reality very few people will ever have the need to drill off 100 photos in 24 seconds, but I can't stand to loose a good shot because the camera is slow while writing to the card and I can't fire the shutter. You can hear this happen at about 4.5 seconds in the video review. This does not happen with the SanDisk class 10 30MB/s card.

A lot can happen in a fraction of a second that can make a shot good or bad and the having ability to fire a lot of shots in rapid succession is important to me.

If you own an SLR that is capable of rapid fire, high-resolution photography you may want to consider the SanDisk Extreme III 30 MB/s card.

If you own a compact digital camera, this card will exceed the capabilities of all of them. For compact cameras the card isn't usually the slowest part of the data write process, it's the camera.

This card is reasonably priced for a class 10 card. Just know what you are getting, what your needs may be, and what else is available. I own other Transcend cards and they have always worked properly without any issues.

The video that I attached shows this card with the same 24 seconds that I gave the SanDisk Card.

Fast!, April 8, 2010
I purchased this for use with my new Canon T2i. I use it primarily for shooting full resolution 1080p video, although I shoot stills as well.

The camera choked on the class 4 chip that I originally purchased, but with this one, it is amazing. I can shoot rapidfire 18 megapixel stills (I've tested it up to 30+ shots in a row), and there is no lag. I've never had an error when shooting hi-def video.

Highly recommended! I'm buying another one.

I did a 10 sec stop watch test on both cards with my Rebel T1i on raw and the Sandisk was only faster by 1 shot in a 10 sec burst. to me it seems trivial to pay 47 bucks for a Sandisk 8gig when you can get 16 gigs for the same price. yes i know, the Sandisk is good for arctic and desert temperatures... but i live in western NY... not Antarctica or the Sahara.

Transcend Vs. Sandisk on Panasonic LX5, November 12, 2010

I own a SanDisk Extreme III class 10 card that has (up to) 30MB/s read and write speed. My Nikon D-90 that can take advantage of the SanDisk cards speed. The difference is the SanDisk card can capture 100 photos at fine resolution in 24 seconds. The Transcend card captures 66 photos in the same time/resolution.

I reality very few people will ever have the need to drill off 100 photos in 24 seconds, but I can't stand to loose a good shot because the camera is slow while writing to the card and I can't fire the shutter. You can hear this happen at about 4.5 seconds in the video review. This does not happen with the SanDisk class 10 30MB/s card.

A lot can happen in a fraction of a second that can make a shot good or bad and the having ability to fire a lot of shots in rapid succession is important to me.

If you own an SLR that is capable of rapid fire, high-resolution photography you may want to consider the SanDisk Extreme III 30 MB/s card.

If you own a compact digital camera, this card will exceed the capabilities of all of them. For compact cameras the card isn't usually the slowest part of the data write process, it's the camera.

This card is reasonably priced for a class 10 card. Just know what you are getting, what your needs may be, and what else is available. I own other Transcend cards and they have always worked properly without any issues.

The video that I attached shows this card with the same 24 seconds that I gave the SanDisk Card.

Sandisk SDSDX3-008G-E31 8GB Extreme III SD Card 30MB/s (RETAIL PACKAGE)

Fast!, April 8, 2010
I purchased this for use with my new Canon T2i. I use it primarily for shooting full resolution 1080p video, although I shoot stills as well.

The camera choked on the class 4 chip that I originally purchased, but with this one, it is amazing. I can shoot rapidfire 18 megapixel stills (I've tested it up to 30+ shots in a row), and there is no lag. I've never had an error when shooting hi-def video.

Highly recommended! I'm buying another one.

Fast, fast, fast!, March 15, 2010
I bought this card for my Canon T1i. The card I had been using before ordering this one was a Kingston Class 6 micro sd card and it worked well enough for the type of shooting I did. Class 6 was the card speed that Canon recommended when I bought my T1i (Class 10 cards were not yet available) and it seemed fast enough for the way I used my camera - isolated single photos taken at Medium (8 MP) or Large (15 MP) jpg settings and 1280 x 720 video. And while I ocassionally took continuous photos, I had never much exceeded 5-10 photos in a row and had never run into a problem with my Class 6 card.

When I first saw the Class 10 cards I did some experiments with my camera. How many continuous Large photos could I take before the camera slowed down? It turned out to be about 30. And how many RAW photos could I take before the camera slowed down? It turned out to be about 9. SInce I did not generally take any photos in RAW and never needed more than about 10 continuous photos at Large, the Class 6 card seemed more than sufficient for my needs. But I wondered about the speed of the Class 10 cards enough that I finally bought one.

It turns out that the Class 10 card is sufficiently fast that there does not seem to be a reasonable upper limit on single Large photos. I have taken 60 on continuous without an issue. And although I still cannot take more than 9 RAW photos on continuous with the Class 10 card, when I am finished taking those photos the camera no longer displays a Wait - writing pictures screen. The RAW photos get written from the built-in memory to the card so quickly that the camera does not need to display the Wait screen.

So this card is fast! Given the way I take photos this purchase was unnecessary, but still I am glad I bought it. I know I will not run into a situation where speed is an issue with this card.

Transcend vs Sandisk of equal price, July 31, 2010
OK. this card was around $47 for a class 10 16gb. The other card i bought was a Sandisk class 10 8gb for the around same price. I did a 10 sec stop watch test on both cards with my Rebel T1i on raw and the Sandisk was only faster by 1 shot in a 10 sec burst. to me it seems trivial to pay 47 bucks for a Sandisk 8gig when you can get 16 gigs for the same price. yes i know, the Sandisk is good for arctic and desert temperatures... but i live in western NY... not Antarctica or the Sahara. If your looking for a good card, with more gigs for your buck, the Transcend is well worth it.

Slower than slow on Pentax K-x, April 25, 2010
I bought this for my pentax K-x but it would randomly corrupt images. Also, it was slower than my 3+ year old SandDisk Ultra 1GB card. I was told by the seller (Thememstore) that others with the k-x have had the same problems. So apparently it must have something to do with the class 10 part, because since I returned this card I bought a SandDisk Extreme III 4GB Class 6 and it works far better.

Would I recommend this card? Yes, but only to someone who knows that class 10 will work in their camera. I don't fault the card as I think the problem is with the K-x.

DESTROYS DATA -- after working fine for just long enough to fool you!, November 6, 2010
SUMMARY:


DO NOT BUY THIS CARD UNLESS YOU WANT TO PLAY RUSSIAN ROULETTE WITH YOUR DATA. Card worked fine when I bought it, but malfunctioned within the first 400 photos -- malfunctioned so badly that some very technical tools were needed to recover anything at all, and some photos were still permanently lost. Recovering the data requires the attention of a serious data recovery expert or someone with substantial technical knowledge and lots of time.


DETAILS:

I made the mistake buying this card for my camera right before a long trip overseas. It worked fine on the first few dozen shots. I didn't see any improvement in speed over my trusty 1.5-year-old Transcend 8GB Class-6 card, but that was most likely because the camera itself (Canon EOS Rebel 1000D/XSi) could not write images any faster than that (full-size JPEG, continuous shutter mode, roughly did ~2.5-3 images/second on both cards, with no slowdown after the first few shots).

200 shots or so into using this card, I get a sudden mysterious message from the camera when I try to take a new shot -- Card Format Invalid (never saw it in the previous 1.5 years on this camera with 3 other SDHC cards). I look around for a bit, and discover that turning the camera off, pulling the card out and putting it back in is enough to clear the error message, and the previous photos are still visible.

I then make the mistake of assuming the problem is just that -- needing to "reboot" the camera when the card is acting stupid, and nothing else. Over the next 200 or so shots, this problem comes up every 50 shots or so. Then, after yet another "reboot", I notice that the camera's playback function is only showing the last 30 photos!!! Yet it shows that there's only 5.7G of space left on the camera -- the other 2G+ _should_ be taken up by the photos I've shot thus far, but the playback doesn't show them.

And this happens in the middle of a trek through the Peruvian Andes, several days' walk/horse ride from the first village with electricity, let alone a computer (with lots of once-in-a-lifetime shots on the camera). I pull this card out immediately, plug in my backup card, and wait until coming back to civilization to take a look at the card. Sure enough, the card is severely corrupted -- the directory listing is showing a bunch of folders with weird-character names, and only the last ~30 photos are visible from the computer, too!


RECOVERY SUGGESTIONS:

Hopefully you'll read this before buying and will not buy this piece of junk card. If you had the misfortune of running into the same problem and losing your data, read on.

I have now had time to examine what was left on the card, using tools that are not easily usable to people without substantial technical training. I've managed to recover over 90% of my photos, but this was NOT easy, and I suspect that even some shops specializing in data recovery from failed disks may not know how to get your data back -- this is NOT as simple as just undeleting a file!

Non-technical instructions:

1. As soon as you see the FIRST error involving the card format, turn off the camera, pull out the card, and copy all of your photos to a different device (computer/harddrive/whatnot). The earlier you stop using this card, the safer your photos will be.

2. As soon as the first problem happens, move the little plastic slider on the side of the card to the "Lock" position -- this will prevent anything else from being written on the card, which lowers the risk of what's left of your photos being overwritten.

3. If you see directories (aka folders) with weird names when you plug this card into a computer -- or see a huge number of photos missing when you look at them on the camera, take the card out IMMEDIATELY, and take the card to a data recovery shop or a technical expert willing to look at the card in depth. Give them a printout of the explanation below.


Technical details:

At least in my case, the filesystem was indeed somehow damaged, perhaps by the camera deciding to write over the location of the root directory somehow. I took a full disk image of the card, and operated on the disk image only (there were no read errors when making the image, FWIW). Somehow I was lucky enough to have the original _subdirectories_ \DCIM and \DCIM\100CANON survive on the card intact even though the root directory structure now pointed to a different, new, place on the filesystem as \DCIM.

I found the location of the old 100CANON directory on the filesystem by searching for one of the filenames I knew would exist in the old directory, like IMG_7000, across the whole disk image.

I then edited the filesystem (yea, with a hex editor!) to have the new \DCIM directory point to the old 100CANON subdirectory. See the Wikipedia article on FAT32 for a reasonably easy reference on how to find the 4 bytes that need to be edited, and how to calculate the correct updated value.

Mounting the edited disk image (with Linux's 'mount -t loop'), the directory was intact, and all but about 5% of the photos were completely intact as well -- the remainder must have been overwritten after the directory structure got corrupted. Depending on how long it takes the user to notice a problem, of course, much more damage could easily happen to the original data.

Here's one easy hack to see how much you can hope to recover, if you're recovering camera data. The same trick may be useful for locating the JPEGs if the original image-containing directory is no longer intact (good luck with recovery then! I thankfully didn't have to do this). Take any image produced by the same camera, look at its JFIF headers. My camera leaves the string "Canon EOS DIGITAL REBEL XS" in two places in every JPEG it creates, early on in the JFIF header. Search for that string across the whole filesystem. If there's, say, 500 hits, that means you can hope for [easy] recovery of at most 250 photos -- any photo that is missing the JFIF headers will be missing the first chunk of the file, and will make it very hard both to find _and_ to reconstruct the remaining data, if any, into a usable JPEG (I have not tried to do this, at least, and it seems very hard).

Transcend Vs. Sandisk on Panasonic LX5, November 12, 2010
I will be writing this review for both SanDisk Extreme SDHC class 10 8gb and Transcend SDHC class 10 16gb.

I bought SanDisk class 10 and Transcend class 10 for my new Panasonic LX5. I got both card because no one really did a comparison with a compact camera and I was just going crazy trying to see if there is any big difference between the 2 cards.

SanDisk Extreme package box indicated it's water proof, x-ray proof, shock proof, temperature proof. I am not ready to spend $50 to see if it really stand up to it's words. And I don't think normal people would go through the extreme condition in taking pictures or videos.

Cut the story short, I really want to see if there is any difference in writing performance between the 2 cards in a compact camera. There is a continuous burst mode in LX5 and the manual indicated it is only limited by the condition of picture environment and performance of the SD card. Within the mode there are 2 different settings:1) speed priority or 2) picture/quality priority. The shutter speed is much faster with speed priority compare to picture priority.

I first formatted both cards out of box then put each card in series of test(3 rounds each setting for each card) shooting at the same object under same lighting condition. The results:
Speed Priority:
SanDisk Class 10 8gb
22-33 shots before camera stopped to allow the card to catch up with writing.

Transcend Class 10 16gb
22-24 shots before camera stopped to allow the card to catch up with writing.

Picture priority
SanDisk Class 10 8gb
34-46 shots before camera stopped

Transcend Class 10 16gb
27-33 shots before camera stopped


It seems that at a higher shutter speed, both cards performed very similar under the same shooting condition. But at a slower shutter speed the SanDisk definitely out perform Transcend. I hope this little experiment satisfied anyone with curiosity like me. Transcend definitely is a bargain with 16gb and almost half of the price compare to SanDisk. But I am going to use SanDisk Extreme as my primary card and Transcend as backup or on a second camera to ensure i would not miss any shots.

Depend on what you will use it for ..., October 13, 2010
The "C10" is for "minimum sustaining speed" of 10mbps. The sustaining speed is critical if you're using for HD camcorder. There is other brand card that is also c10 but it costs more (2x) for its print of 30mbps on the card. It leads consumers into thinking that the higher price is worth for the 30mbps. However, the 30mbps is the "burst" speed. Burst speed is critical for HD camera and for doing copies. I have a HD camcorder and I'm very satisfied with this card after many hours for recording. I bought this card to do 100% of recording so it is the right price. I would buy the other high price brand card of 30mbps if I will do a lot of picture taking. The bottom line is to buy for the purpose of your usage.

Not very fast, April 14, 2010
On my Panasonic GF1, it's the same speed as a Class 6 Transcend card and much slower than a Class 10 SanDisk Extreme. Buy the Transcend Class 6 if you want to save money or the SanDisk if you wan speed, but skip this one.

Great affordable SDHC card, March 28, 2008
In the past, I bought a Transcend 8GB SDHC card for my Canon SD1000 camera. I recently bought the Transcend 16GB SDHC for my new Canon SX20IS. Both cards work very well and I've had no problems with it so far. I wanted to take this opportunity to update my review since my original review was also posted (by Amazon) for the 16GB card. This is because the only difference between these two cards is the different capacity. So, if you're in the market for an affordable high quality SDHC card, this may be the one for you. Sorry, I kind of sounded like a used car salesman right there, didn't I? I assure you that I don't work for Transcend. But, here's why I think this card is awesome:

Pros:

-Affordable!

-Large capacity

-Class 6 read/write speed (which is very fast... but is no longer the fastest class available)

-Lifetime warranty (at least that's what the package says :)

-Transcend is a reputable company that's been making memory products for a very long time. ( I swear to the tech Gods that I don't work for them!) Other reputable and reliable memory card companies include Kingston and PNY. All three of these companies have been making memory chips for many, many years.


Cons:

- I can' really think of any "Cons" about this card. But here's the 2 closest things I can come up with right now: (1) "Class 6" is no longer the fastest speed available and (2) This card does NOT make coffee for you in the morning, do your dishes for you, give you compliments when you're having a bad day, or magically improve your photography skills.




IMPORTANT SPECIAL NOTES ABOUT SDHC MEMORY CARDS:

-SDHC cards are not compatible with most older SD cameras, SD devices, or SD card readers.

-SDHC cards are rated by speed using different "classes". There are currently 4 data transfer speed classes available for SDHC cards. These classes are "class 2, class 4, and class 6, and the new class 10. For example, "Class 2" would have the slowest read/write speed while "Class 6" has the fastest read/write speed. So if you have a device in which speed may play a crucial role, make sure you buy a higher "class" SDHC card. Please note that this SDHC card no longer has the fastest read/write speed available. There is now a new class, called "Class 10". Class 6 has a minimum read/write speed of 6MB/sec... while Class 2 has minimum speed rating of 2MB/sec, and Class 4 is 4MB/sec. Starting to see the pattern?


SO WHAT'S THE DIFFERENCE BETWEEN "SD CARDS" AND "SDHC CARDS?

SDHC is basically an upgrade to the older SD cards. The reason they upgraded it was to achieve greater data transfer speeds AND capacity than previously possible with normal SD cards... and to do this, they had to redesign the card (which is why it's not compatible with normal SD devices). This was necessary because digital cameras and digital video cameras these days have higher resolutions, which equate to larger file sizes and faster data transfer needs.

Now that many digital cameras also can record HD video, you may consider getting a larger capacity card because video takes much more space than photos. The size of the video varies from camera to camera depending on what resolution and video compression the camera uses. If you plan on taking lots of video (especially HD video), I would consider getting at least a 16GB card. Check your camera specifications to see how many minutes per Gig of memory your camera can capture ...to gauge how big of a memory card you'll want to get to meet your needs.

Special Note on regular SD Cards:
If you primarily take casual photos and don't need a exceptionally fast read/write capable card, you should know that newer cameras that take "SDHC" cards will also work with older normal "SD" cards. These older cards are cheaper than the new SDHC cards, so this may be something to consider. So to sum things up, newer cameras will take SDHC and regular SD cards, but older cameras that use SD cards may not be able to use SDHC cards. This is because newer technology is usually made to be compatible with older technology (the technical term used to describe this is "backwards compatibility") ... but older technology may not have the hardware necessary to run newer tech (technical term used is "obsolete"... just kidding! ;)

I hope I haven't confused everybody by going into this much detail, but I can't help being the nerd that I am. If you are confused, don't hesitate to comment on this post and I will try my best to answer your questions. Also, any feedback is always welcome!

Conclusion: Buy the card if you have a new device that uses SDHC. It rocks! (This message has been approved by the "Duke of New Mexico")

Transcend 4 GB Class 6 SDHC Card - Good Card for SDHC Compatible Devices, May 10, 2008
UPDATE - March 2, 2010: This review was originally written for the 4 GB class 6 SDHC card, but the reviews have been grouped for all class 6 SDHC cards in the 4, 8, 16 and 32 GB sizes. All the cards should perform similarly since they are all class 6 and all made by Transcend. However, I will have to check which cards I have used hands on. I believe I only own the 4GB and 8GB cards. I will update the review further. If you have concerns regarding the 16GB or 32GB sizes, you should seek out the reviews tagged with the product links from those cards.


The Transcend 4GB SDHC CARD (Class 6) is a great card for the price. I was at first a little skeptical about the brand, but I buy way too many memory cards to ignore a good price when I see one. And I'm happy to report that I've experienced decent performance and reliability issues with this card. That's as compared to other cards I own including SanDisk, PNY and Kingston.

As long as your devices are compatible with the SDHC format, this card is a good buy. 4 GB is a nice size though I do prefer 8 GB capacity for high capacity storage.

The class 6 speed is the fastest speed available in mass market SDHC cards. Class 6 guarantees minimum transfer speeds of 6 MBs, but I've gotten speeds up to 20Mbs! That makes this card perfect for storing pictures in RAW image formats.

The Class 6 speed is on par with the Sandisk Extreme III cards that on average are about $15 to $20 more per card. If you don't have an SDHC reader, you may opt to get the package with a reader included to download your pics. If not you can just transfer your pics directly from your camera with your card still inserted. An SDHC card reader can be bought separately if your PC doesn't have a compatible slot.

General SDHC and SD Card Tips

There are a few tips that I've learned the hard way through buying TOO MANY different memory cards.
1. Make sure your device is compatible with the card! Even in regular SD cards, some older electronics aren't compatible with that large of a size (2 GB). In terms of SDHC cards, make sure your camera or other device is SDHC compatible. SDHC is different from regular SD and only newer devices tend to have built-in compatibility
2. Once you install this in your camera or device, you will generally want to format the card with your compatible device's interface. That is because the standard formats for certain devices, particularly Canon, are different from the factory installed format
3. Just like your devices, most computer SD card readers are not compatible with the SDHC format. So use a card reader or download the pictures via USB connection to the camera with the card still installed.
4. For some reason, placing the card in the locked position allows some older laptops to still read it. This is just to be used in a pinch however, and it won't apply to all systems
5. If you did not properly format your card, you may be able to save things to it and then have them "disappear." If this happens to you, make sure you use the software recovery tools BEFORE you try to save anything else to your card. That way, you can retrieve your images without over-writing them.
6. Make sure you know what you are going to use this card for. Once you have set up everything and ensured it's all compatible, you still have to decide on speed. If you are using this for storing RAW images instead of JPEGs or HD video, step up to the faster class 6 speed format if you can afford it.
7. If you are going to pay more for a faster speed, make sure your device can benefit from it. I've read, for example, that Kodak cameras are set to a fixed voltage and cannot go faster than standard speed. So the extra cash spent on Class 4, 5, or 6 is basically wasted.

Conclusion

It's great to have several extra cards on hand just in case. This 4 GB card is a nice performer. If you have a high capacity camera (10 Megapixels or more) and are storing videos or RAW images, the extra cash for the 8GB card is worth it. Or you may want to step up to the larger 16 GB size that is now available.

Enjoy!

Transcend 32 GB SDHC Review, May 25, 2009
Before you drop 120~$ for a SD card ask yourself, Do you really need 32GB card? because the card itself with same specs costs only 35$ for the 16GB version, anyway here is info that might help you

Pros :
1- Class 6 Card the(guaranteed minimum Read/write speed of 6MB/s)
2- My Test Results 18.2-18.5MB/S Read - 11.6-11.8 Write (very stable)
3- Faster than average cards and almost close to top speed SDHC cards
4- 32GB in a single small chip is awesome(You can use it as a portable HD once in a while, i share some stuff with my friends with it sometimes


Cons :
1- Expensive
2- You can get two 16GB cards for around only 70$ and save yourself 50$~
3- Slow write speeds for a 32GB card (Takes forever to fill it with DATA from PC, its not the card fault though , its just the SDHC technology is getting old and slow for 2009 standards , time for newer Tech)

* Important Info

Avoid the Sandisk Ultra Series they never reach the true marketed speed "15MB-20MB/S" its just in theory speed like how everybody knows that USB2 is much slower than its specs, and they are only Class 2 for the 32GB version which will drop frames from your HD video (Plus Class 4 is minimum requirement for shooting in HD ) if you plan to get San disk Card then get the Extreme III Series (but again from my own Tests there read speed is about 20MB not 30MB and the write speed is 14MB/s~ instead of the transcend 11MB/s write speed (Unless you spam shooting pictures with your DSLR you don't "need" faster speed)

I bought This card because i plan to take videos with my HD camcorder that last more 2 Hours, if you do not plan to shoot for longtime then you are better with getting the 16GB card HOWEVER, if you are lazy like my mom and do not plan to transfer DATA from the card to Your computer HD after every trip, then get the 32GB card.or you gonna end up on a trip and a message pops "No memory"

If you plan to shoot for longer time, check your camcorder battery too does it even last that long? so be sure about that before you drop over 100$ for this card

product failed., July 26, 2009
I recently purchased a Canon Powershot A720IS digital camera that is capable of recognizing and using up to 2 TERRABYTES of memory card (in the future) so I wanted to get the largest memory card I could install for now. I wanted to use the camera both on dry land and with an underwater housing for shooting stills and video on dive trips. Camera specs said an 8 GB SDHC card would record one hour of hi res video at 30 fps. Or nearly 2300 hi res stills at 8 megapixels.

A test of the Transcend 8GB SDHC card in the camera ended up shooting 70 minutes of full screen, 30fps digital video that could not be distinguished from my DV camcorder video quality. Playback from the memory card to the TV was so fast & efficient there was never a single "stutter" on the screen. The card speed is genuinely FAST as advertised. Low level formatting of the card allowed for very acceptable rapid-fire sequential still photo shooting speeds when light levels were bright enough that the flash was not needed/used. Something like 2 photos every 3 seconds. Files were flawless in display, both for stills and video.

This product was significantly lower in price than the Kingston 8GB SDHC card I originally bought with the camera. I've used both interchangeably and cannot see any different in the speed or capacity and quality of imagery is identical. For the money I'll stick with Transcend and am looking forward to getting their 16GB card once the price drops substantially below the $100 mark. That would provide nearly 2 1/2 hours of video on my still camera or 4600 highest quality stills. I'm afraid my camcorder will be collecting dust much of the time. A big advantage to video on the card is there are NO MOVING PARTS, e.g. a mini DV tape cassette and camcorder or VCR playback unit needed to dump the video and stills to my Mac for editing and burning DVDs. I just stick the card in the MicroMate USB card reader, plug it in the computer and bingo, ready to sort thru and dump to the hard drive. Since the card is formatted by a Canon camera it automatically boots up the Canon Viewer software too. That should work the same for other brands of still cameras formatting this chip.

The Fastest Card at This Price But..., June 26, 2007
This SDHC card is the fastest one in its price range but it may cause your images to be lost.

I use two of this in a Canon SD750. After the first use, all of the images were lost. (But thank God, I could rescue them with Lexar Image Rescue 2, a program better than its competitors) Then I formated the card(s) in the camera(s) with "low level format" option several times and there has been no problem after that so far.

I can suggest these points to potential owners of this card:
1- Use it very carefully, make backups if possible.
2- Format it several times before the first use with "low level format" option.
3- If you loose your images, don't panic. At this situation, It is very important not to take anymore pictures. If you take pictures after this point, you can overwrite your lost images and there can be no chance to get them back. Connect your card to your computer with a card reader (SDHC Compatible) and rescue them with Lexar Image Rescue.

Excellent Mini Hard Drive equivalent, December 11, 2007
This card is able to hold a complete DVD movie, thousands of songs/photos, or just serve as a backup device for one's files.

It operates very well - I now have purchased 3 and with each use its value becomes more apparent.

One word of caution - even though most laptops and systems have an SD card slot, older computers may not be able to recognize or write to this card. Make sure your system has the ability to read SDHC configured products.

If you do not have an SD slot you can purchase an tiny SD reader (very inexpensive) that plugs into your USB port.

Great value, just be careful..., January 2, 2009
It's great to have 8GB of memory but it is a double edged sword. Today after using this card for only the second time, it failed on me. I lost almost 200 precious images - gone forever. I am what you would call an enthusiast or hobbyist. I love photography and spend every spare minute, which is very seldom these days, pursuing my passion. So I do a fair amount of experimentation. These cards are great when they work - but if they fail you even once - the results can be catastrophic. Maybe I am the unlucky 1 of 250 reviewers with a bad experience with this product, but I feel it is my responsibility to report this to everyone. I hope it never happens to you. It is human nature for me to wonder, if I had spent a few more dollars for a better brand name, would my photos be intact today?

Great affordable SDHC card, March 28, 2008
In the past, I bought a Transcend 8GB SDHC card for my Canon SD1000 camera. I recently bought the Transcend 16GB SDHC for my new Canon SX20IS. Both cards work very well and I've had no problems with it so far. I wanted to take this opportunity to update my review since my original review was also posted (by Amazon) for the 16GB card. This is because the only difference between these two cards is the different capacity. So, if you're in the market for an affordable high quality SDHC card, this may be the one for you. Sorry, I kind of sounded like a used car salesman right there, didn't I? I assure you that I don't work for Transcend. But, here's why I think this card is awesome:

Pros:

-Affordable!

-Large capacity

-Class 6 read/write speed (which is very fast... but is no longer the fastest class available)

-Lifetime warranty (at least that's what the package says :)

-Transcend is a reputable company that's been making memory products for a very long time. ( I swear to the tech Gods that I don't work for them!) Other reputable and reliable memory card companies include Kingston and PNY. All three of these companies have been making memory chips for many, many years.


Cons:

- I can' really think of any "Cons" about this card. But here's the 2 closest things I can come up with right now: (1) "Class 6" is no longer the fastest speed available and (2) This card does NOT make coffee for you in the morning, do your dishes for you, give you compliments when you're having a bad day, or magically improve your photography skills.




IMPORTANT SPECIAL NOTES ABOUT SDHC MEMORY CARDS:

-SDHC cards are not compatible with most older SD cameras, SD devices, or SD card readers.

-SDHC cards are rated by speed using different "classes". There are currently 4 data transfer speed classes available for SDHC cards. These classes are "class 2, class 4, and class 6, and the new class 10. For example, "Class 2" would have the slowest read/write speed while "Class 6" has the fastest read/write speed. So if you have a device in which speed may play a crucial role, make sure you buy a higher "class" SDHC card. Please note that this SDHC card no longer has the fastest read/write speed available. There is now a new class, called "Class 10". Class 6 has a minimum read/write speed of 6MB/sec... while Class 2 has minimum speed rating of 2MB/sec, and Class 4 is 4MB/sec. Starting to see the pattern?


SO WHAT'S THE DIFFERENCE BETWEEN "SD CARDS" AND "SDHC CARDS?

SDHC is basically an upgrade to the older SD cards. The reason they upgraded it was to achieve greater data transfer speeds AND capacity than previously possible with normal SD cards... and to do this, they had to redesign the card (which is why it's not compatible with normal SD devices). This was necessary because digital cameras and digital video cameras these days have higher resolutions, which equate to larger file sizes and faster data transfer needs.

Now that many digital cameras also can record HD video, you may consider getting a larger capacity card because video takes much more space than photos. The size of the video varies from camera to camera depending on what resolution and video compression the camera uses. If you plan on taking lots of video (especially HD video), I would consider getting at least a 16GB card. Check your camera specifications to see how many minutes per Gig of memory your camera can capture ...to gauge how big of a memory card you'll want to get to meet your needs.

Special Note on regular SD Cards:
If you primarily take casual photos and don't need a exceptionally fast read/write capable card, you should know that newer cameras that take "SDHC" cards will also work with older normal "SD" cards. These older cards are cheaper than the new SDHC cards, so this may be something to consider. So to sum things up, newer cameras will take SDHC and regular SD cards, but older cameras that use SD cards may not be able to use SDHC cards. This is because newer technology is usually made to be compatible with older technology (the technical term used to describe this is "backwards compatibility") ... but older technology may not have the hardware necessary to run newer tech (technical term used is "obsolete"... just kidding! ;)

I hope I haven't confused everybody by going into this much detail, but I can't help being the nerd that I am. If you are confused, don't hesitate to comment on this post and I will try my best to answer your questions. Also, any feedback is always welcome!

Conclusion: Buy the card if you have a new device that uses SDHC. It rocks! (This message has been approved by the "Duke of New Mexico")

Transcend 4 GB Class 6 SDHC Card - Good Card for SDHC Compatible Devices, May 10, 2008
UPDATE - March 2, 2010: This review was originally written for the 4 GB class 6 SDHC card, but the reviews have been grouped for all class 6 SDHC cards in the 4, 8, 16 and 32 GB sizes. All the cards should perform similarly since they are all class 6 and all made by Transcend. However, I will have to check which cards I have used hands on. I believe I only own the 4GB and 8GB cards. I will update the review further. If you have concerns regarding the 16GB or 32GB sizes, you should seek out the reviews tagged with the product links from those cards.


The Transcend 4GB SDHC CARD (Class 6) is a great card for the price. I was at first a little skeptical about the brand, but I buy way too many memory cards to ignore a good price when I see one. And I'm happy to report that I've experienced decent performance and reliability issues with this card. That's as compared to other cards I own including SanDisk, PNY and Kingston.

As long as your devices are compatible with the SDHC format, this card is a good buy. 4 GB is a nice size though I do prefer 8 GB capacity for high capacity storage.

The class 6 speed is the fastest speed available in mass market SDHC cards. Class 6 guarantees minimum transfer speeds of 6 MBs, but I've gotten speeds up to 20Mbs! That makes this card perfect for storing pictures in RAW image formats.

The Class 6 speed is on par with the Sandisk Extreme III cards that on average are about $15 to $20 more per card. If you don't have an SDHC reader, you may opt to get the package with a reader included to download your pics. If not you can just transfer your pics directly from your camera with your card still inserted. An SDHC card reader can be bought separately if your PC doesn't have a compatible slot.

General SDHC and SD Card Tips

There are a few tips that I've learned the hard way through buying TOO MANY different memory cards.
1. Make sure your device is compatible with the card! Even in regular SD cards, some older electronics aren't compatible with that large of a size (2 GB). In terms of SDHC cards, make sure your camera or other device is SDHC compatible. SDHC is different from regular SD and only newer devices tend to have built-in compatibility
2. Once you install this in your camera or device, you will generally want to format the card with your compatible device's interface. That is because the standard formats for certain devices, particularly Canon, are different from the factory installed format
3. Just like your devices, most computer SD card readers are not compatible with the SDHC format. So use a card reader or download the pictures via USB connection to the camera with the card still installed.
4. For some reason, placing the card in the locked position allows some older laptops to still read it. This is just to be used in a pinch however, and it won't apply to all systems
5. If you did not properly format your card, you may be able to save things to it and then have them "disappear." If this happens to you, make sure you use the software recovery tools BEFORE you try to save anything else to your card. That way, you can retrieve your images without over-writing them.
6. Make sure you know what you are going to use this card for. Once you have set up everything and ensured it's all compatible, you still have to decide on speed. If you are using this for storing RAW images instead of JPEGs or HD video, step up to the faster class 6 speed format if you can afford it.
7. If you are going to pay more for a faster speed, make sure your device can benefit from it. I've read, for example, that Kodak cameras are set to a fixed voltage and cannot go faster than standard speed. So the extra cash spent on Class 4, 5, or 6 is basically wasted.

Conclusion

It's great to have several extra cards on hand just in case. This 4 GB card is a nice performer. If you have a high capacity camera (10 Megapixels or more) and are storing videos or RAW images, the extra cash for the 8GB card is worth it. Or you may want to step up to the larger 16 GB size that is now available.

Enjoy!

Transcend 32 GB SDHC Review, May 25, 2009
Before you drop 120~$ for a SD card ask yourself, Do you really need 32GB card? because the card itself with same specs costs only 35$ for the 16GB version, anyway here is info that might help you

Pros :
1- Class 6 Card the(guaranteed minimum Read/write speed of 6MB/s)
2- My Test Results 18.2-18.5MB/S Read - 11.6-11.8 Write (very stable)
3- Faster than average cards and almost close to top speed SDHC cards
4- 32GB in a single small chip is awesome(You can use it as a portable HD once in a while, i share some stuff with my friends with it sometimes


Cons :
1- Expensive
2- You can get two 16GB cards for around only 70$ and save yourself 50$~
3- Slow write speeds for a 32GB card (Takes forever to fill it with DATA from PC, its not the card fault though , its just the SDHC technology is getting old and slow for 2009 standards , time for newer Tech)

* Important Info

Avoid the Sandisk Ultra Series they never reach the true marketed speed "15MB-20MB/S" its just in theory speed like how everybody knows that USB2 is much slower than its specs, and they are only Class 2 for the 32GB version which will drop frames from your HD video (Plus Class 4 is minimum requirement for shooting in HD ) if you plan to get San disk Card then get the Extreme III Series (but again from my own Tests there read speed is about 20MB not 30MB and the write speed is 14MB/s~ instead of the transcend 11MB/s write speed (Unless you spam shooting pictures with your DSLR you don't "need" faster speed)

I bought This card because i plan to take videos with my HD camcorder that last more 2 Hours, if you do not plan to shoot for longtime then you are better with getting the 16GB card HOWEVER, if you are lazy like my mom and do not plan to transfer DATA from the card to Your computer HD after every trip, then get the 32GB card.or you gonna end up on a trip and a message pops "No memory"

If you plan to shoot for longer time, check your camcorder battery too does it even last that long? so be sure about that before you drop over 100$ for this card

product failed., July 26, 2009
Well, it was great while it lasted. Unfortunately, it did not last long.

Like other reviewers, after <20 use cycles the device failed and I got a "lock" error when, in fact, the write-protection lock was not engaged. Oddly, by engaging the lock (i.e. entering read-only mode) I was able to remove the picture files from the card. Obviously, further use in the camera was impossible; I was also unable to reformat the card (either with my camera or with the SD Associations free software [..]).

This card has a high average rating but I would urge customers to consider the number of 1-star ratings due to complete product failure before they purchase this item.

My Canon loves the 8 GB SDHC card, January 15, 2008
I recently purchased a Canon Powershot A720IS digital camera that is capable of recognizing and using up to 2 TERRABYTES of memory card (in the future) so I wanted to get the largest memory card I could install for now. I wanted to use the camera both on dry land and with an underwater housing for shooting stills and video on dive trips. Camera specs said an 8 GB SDHC card would record one hour of hi res video at 30 fps. Or nearly 2300 hi res stills at 8 megapixels.

A test of the Transcend 8GB SDHC card in the camera ended up shooting 70 minutes of full screen, 30fps digital video that could not be distinguished from my DV camcorder video quality. Playback from the memory card to the TV was so fast & efficient there was never a single "stutter" on the screen. The card speed is genuinely FAST as advertised. Low level formatting of the card allowed for very acceptable rapid-fire sequential still photo shooting speeds when light levels were bright enough that the flash was not needed/used. Something like 2 photos every 3 seconds. Files were flawless in display, both for stills and video.

This product was significantly lower in price than the Kingston 8GB SDHC card I originally bought with the camera. I've used both interchangeably and cannot see any different in the speed or capacity and quality of imagery is identical. For the money I'll stick with Transcend and am looking forward to getting their 16GB card once the price drops substantially below the $100 mark. That would provide nearly 2 1/2 hours of video on my still camera or 4600 highest quality stills. I'm afraid my camcorder will be collecting dust much of the time. A big advantage to video on the card is there are NO MOVING PARTS, e.g. a mini DV tape cassette and camcorder or VCR playback unit needed to dump the video and stills to my Mac for editing and burning DVDs. I just stick the card in the MicroMate USB card reader, plug it in the computer and bingo, ready to sort thru and dump to the hard drive. Since the card is formatted by a Canon camera it automatically boots up the Canon Viewer software too. That should work the same for other brands of still cameras formatting this chip.

The Fastest Card at This Price But..., June 26, 2007
This SDHC card is the fastest one in its price range but it may cause your images to be lost.

I use two of this in a Canon SD750. After the first use, all of the images were lost. (But thank God, I could rescue them with Lexar Image Rescue 2, a program better than its competitors) Then I formated the card(s) in the camera(s) with "low level format" option several times and there has been no problem after that so far.

I can suggest these points to potential owners of this card:
1- Use it very carefully, make backups if possible.
2- Format it several times before the first use with "low level format" option.
3- If you loose your images, don't panic. At this situation, It is very important not to take anymore pictures. If you take pictures after this point, you can overwrite your lost images and there can be no chance to get them back. Connect your card to your computer with a card reader (SDHC Compatible) and rescue them with Lexar Image Rescue.

Excellent Mini Hard Drive equivalent, December 11, 2007
This card is able to hold a complete DVD movie, thousands of songs/photos, or just serve as a backup device for one's files.

It operates very well - I now have purchased 3 and with each use its value becomes more apparent.

One word of caution - even though most laptops and systems have an SD card slot, older computers may not be able to recognize or write to this card. Make sure your system has the ability to read SDHC configured products.

If you do not have an SD slot you can purchase an tiny SD reader (very inexpensive) that plugs into your USB port.

Great value, just be careful..., January 2, 2009
I recently ordered this card as an accessory for my Acer Aspire One netbook PC. The card took a little while to ship, about 8 days, but that wasn't a big deal. The card has lots of space, and the read speeds are quite impressive. I mostly use it to run and store portable software, and it does a very good job at that.

My only complaint is that when I first inserted the card into my PC it attempted to install some adware. The program was from a company called RelevantKnowledge, and they gather your information for market research purposes. Luckily my spyware software picked it up immediately,so I was able to delete it. Afterward I formatted the card, and now I'm happy as can be.

Reliable card, good speeds!, December 4, 2008
Transcend 16 GB SDHC SD Class 6 Flash Memory Card TS16GSDHC6E [Amazon Frustration-Free Packaging]
I have 4 of these cards that I use in my Panasonic HMC-150, a professional grade video camera. I've run read/write tests on all of them and they get about 14 MB/s write speeds and 17.5 MB/s read speeds. Never encountered any errors! These cards are the best bang for your buck, and the frustration free packaging is awesome.

Don't Let This Happen to You....., August 3, 2008
It's great to have 8GB of memory but it is a double edged sword. Today after using this card for only the second time, it failed on me. I lost almost 200 precious images - gone forever.
