Excellent uSDHC card!!!,
August 28, 2011 I tested this device under lab conditions. here are the results:
Testing conditions:
interface: Kingston USB card reader with USB 2 high speed PC interface.
Tested with and without the supplied uSD to SD card interface.
Write speed: 12MB/Sec.
Read speed: 18MB/Sec.
Capacity: 8,010,072,064 Bytes (after formatting).
Formatted file system: FAT32.
this uSD may be fast enough for full HD recording in real time, since it has a 12MB/sec write speed which is 96Mbit/Sec.

April 26, 2012 I bought two of these for an Android phone (Captivate) and tablet (Nook Color). The Nook Color is running Android (CM9) on the card itself, while the Captivate is using the card for extra storage. So far, both are running just fine without a problem.
