Kingston, we have a problem...
By NLee the Engineer
Prior to the purchase of this item ("Kingston 16 GB Class-10 SDHC card"), I have bought several other Kingston memory cards, including the Kingston 16 GB Class 4 SDHC and Kingston 8 GB Class 4 microSDHC Card. They were all reasonably priced, and performed up to specifications. So I never had a problem with Kingston - until this time.

I benchmarked the Kingston SD10G2 card upon its arrival. The result I got was so appalling that I have to re-run the tests on two different computers to confirmed it: This so-called 'Class-10' card is actually much slower than any of the 'class-4' SDHC card I have ever tested before!

- When writing small files of 1MB each, the speed of this card is painfully slow at just 0.8MB/s
- When writing larger files of 5MB each, the speed increased to 4.9MB/s
(see the screen capture I uploaded to Customer Images section for details)
- Only when writing a huge file of 1GB size, the speed finally reached 10.7MB/s.

In contrast, the Transcend 16GB TS16GSDHC10 (which is also classified as 'class-10') delivered 9.9MB/s when writing 1MB files, and 12.8MB/s for 5MB files. In fact, even my previous Kingston 16GB class-4 card gave much better results of 3.7 and 8.0MB/s, respective.

In order for a SDHC card to be marketed as 'class-10', it must have a MINIMUM read/write speed of 10 Mega Byte per second. This Kingston 'class-10' card, however, can only achieve a MAXIMUM write speed of 10.7MB/s. So it seems like the marketing people at Kingston don't even understand the difference between "Minimum" and "Maximum". Either that, or they just flat out lied.

As of this writing, you can buy other cards (such as the HP 16 GB Class 4 SDHC) for less but get better performance than this 'class-10' card. Also as a matter of principle, I refuse to support any company engaging in this kind of deceptive marketing techniques. This card is going back for a refund, and I will be leery of other Kingston products from now on.

[Update on Aug 8, 2011]
A Kingston representive contacted me concerning my problem with the write speed. However, I have already returned this Kingston card and purchased a PNY 16 GB Class 10 SDHC Card P-SDHC16G10-EF. The PNY card gave me a solid class-10 performance. See my Amazon review on it for details.

Disappointing for a Class 10 Card
By Scott Akerman
I bought this card to upgrade my Pentax k-x from the 4 GB class 4 SD card I received when I purchased it. I definitely needed more storage for shooting in RAW but I was also looking for a good speed increase for burst mode, and I was hoping this card could satisfy both of my needs at a modest price. The size is definitely there but the speed is very disappointing. Using multiple disk testers I've only been able to push out ~5 megabytes/second maximum write speed but the average remains much lower, only around 3 megabytes/second. Read speeds usually hover around 7 megabytes/second. The box claims the card is capable of up to a 20 MB/s read and 15 MB/s write but my data comes no where near those numbers and I have no idea how they arrived at them. After reading the terrible reviews of the Kingston 16 GB Class 10 Secure Digital Flash Card SD10/16GB I was hoping that this second generation would have fixed those problems, now I'm just hoping it doesn't corrupt my data.

Update: I hoped that I could still use this card on a day-to-day basis and overlook the speed issue, but the slowness of it is noticeable and a reminder that I'm not getting what I paid for. Sending it back for a refund and going to spend a bit more on a much better card.

These cards are not class 10 speed
By mepster
These cards are not class 10 speed. My camera needs only class 6 to record video. Ordered this card, camera gives message "the recording has been stopped automatically" - this means the buffer has filled, the card cannot keep up. Returned card (Amazon does free exchange). Received second card. Same problem! This time I missed the 30 day Amazon return window because I was on vacation (taking pictures!). Feel ripped off. Have not had trouble with previous Kingston cards, just with this model (twice!). (P.S. Camera works fine with other card (at least class 6).)

Either Kingston has a problem, or Amazon is getting duped by a counterfeit supplier - Amazon you should look into it.
