Review on SanDisk Ultra 16GB 80MB/s UHS-I Class 10 microSDHC Card (SDSQUNS-016G-GN3MN) by Michael Powell

I test every SD card I receive with h2testw for read/write speed and capacity. at full power. The write speed is typical for the segment and is 19.3 MB/s. That's not as bad as the "red" cards, which are 13.6 MB/s. Read speeds are the same as any other card I've tested at 78.3MB/s (perhaps a limitation of my setup?). The capacity is 15185MB. The packaging requires you to use a knife to cut the Micro SD from the membrane that holds it in the plastic carrier. One star off for defective sectors and another for disappointing packaging.
