A-DATA 16GB Class 6 Turbo SDHC card with High-Speed 4-in-1 USB Reader. Review

I bought the A-Data 16GB Class 6 Turbo SDHC card to use in my Canon PowerShot A570 IS camera. (Yeah, it's probably incredible overkill, but I really wanted the large memory capacity.) The card was purchased in June, 2009, and has been used extensively since then with no problems whatsoever.
On inserting the SDHC card into the camera, the card was immediately recognized and quickly formatted. The camera takes 7.1-megapixel images; this card has the capacity to store 5107 of the highest-quality photos or two-and-a-quarter hours of the highest-quality video (according to the camera display).
Regarding data-transfer speed, I attached the card to my Dell Inspiron E1705 laptop and timed how long it took to load the empty card with several files that totaled about 14.9 GB. When plugged into the SD/MMC slot, the transfer rate was 3.37 MB per second; when attached to a USB port (through the neat adapter that was shipped with the card), the transfer rate was 6.63 MB per second. As I understand the SDHC rating system, the USB transfer rate makes this a Class 6 card with a 40x rating - the lowest Class 6 rating. The card can be used for the Microsoft "Vista" Ready-Boost feature, if you are so inclined.
The SDHC card I received was manufactured in Taiwan and shipped mounted on a factory-sealed display card, on which the USB adapter was also mounted.
Before ordering this SDHC card, I read most of the comments sent in by other purchasers - particularly the negative comments. Considering the price of the card, I felt the benefit-to-risk ratio was great enough to make the gamble of purchasing this card worthwhile.

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")

Regarding complaints about performance with HD camcorders:
SDHC cards are rated in MegaBytes per second (MB/sec). HD camcorders are rated in Megabits per second (Mb/sec). There are 8 bits per Byte.
Therefore, an HD camcorder with 24Mb/sec video capture requires (24Mb/sec) / (8Mb/MB) = 3MB/sec SDHC card. A Class 4 SDHC card with at least 4MB/sec data transfer is more than enough to capture full HD. Those camcorders are not designed to work with Class 6 and Class 10 cards.
Remember that Full HD, 1920 x 1080 pixels = 2,073,600 pixels, or 2 Megapixels. Digital SLRs shoot at 12 Megapixels with minimal lag time between shots requiring much higher data transfer rates than HD camcorders.
Consequently, people who use Extreme Class 10 SDHC cards with high speed digital SLRs seem happy, but people using them with HD camcorders are not. It can be confusing, but you must use the appropriate card for your application. Faster is not always better.
