This "Ultra High Speed" card is about half the speed of the Class 4 card I was using.  10MB/s Read and 6MB/s write is more than a little below where a device with this rating should perform.  I could believe if it was the same speed as my old card, maybe my brand new Samsung Galaxy Tab 2 7 doesn't have a UHS1 rated port, but to be half the speed of my Class 4 card, this "UHS1" thing clearly is penciled on by marketing monkeys and sold without any testing or quality control. I wish I knew how to rate with 0 stars.
