[Super Talent's] SuperSpeed USB 3.0 RAIDDRive comes in 32GB, 64GB and 128GB capacities and works with current USB 2.0 ports, but obviously at USB 2.0 speed. Plug it into a proper USB 3.0 port and it transfers data much, much faster, at up to a nominal 4.8Gb/s. It should be ten times faster than USB 2.0, which runs at up to 480Mb/s, and this will make a big difference to large data transfers.

Apparently, the only mobo I know that supports USB 3.0 is Asus' P7P55D-E. Any others out there?
