Digital Cameras Photo Reviews of SanDisk Extreme 30MB/s SDHC Flash Memory Card - 16 GBCustomer Review: Beware, and read before buying Summary: 1 Stars
The item pictured and named is NOT the product I received. It is neither the item pictured, nor the item listed in my amazon order history. The item I thought I was purchasing was SanDisk 16GB Extreme SDHC Class 10 High Performance memory card.
However I received a "SanDisk Flash 16 GB SDHC Flash Memory Card SDSDXP1-016G Black". You can search for that product in the amazon search window. The card is simiiar, but with a few key differences. The main difference is that it's not class 10, its SDHC UHC-I. It's not rated at 30MB/s, it's rated at 45MB/s.
So what's the big deal? Obviously, it's rated higher. Well, SDHC UHC-I might not be compatible with some cameras or devices that you or I have. Furthermore, the product I received is cheaper from the other retailers. Had I known what I was receiving, I could/would have bought it from someone else.
Here are the speed tests for the card I received, the first is with this laptop with a usb card reader, the second is from this laptop with the internal factory card reader, and the third is with a different desktop pc with the internal card reader (I tested 2GB with all readers):
USB card reader:
Warning: Only 2000 of 15185 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 15.2 MByte/s
Reading speed: 16.9 MByte/s

Desktop factory Card Reader:

Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 17.6 MByte/s
Reading speed: 19.5 MByte/s

So, it's not nearly as fast as it says (45MB/s). And most if not all cards are not as fast as they say. Just be informed before you purchase.
