USB 3.0 is slowly creeping into our hardware, kicking that stone-age and sluggish USB 2.0 to the curb. One of the latest product families announced to take advantage of USB 3.0 is called the SHD-PEHU3 line, from Buffalo.
These are new external SSDs that theortically can transfer up to 244MB/s, if used with Buffalo's Turbo PC software included with the drives. These are quite fast transfer rates.
For $282 USD you can get the 64GB drive. $510 for the 128GB drive. And $1079 for the 256GB drive.
Expect to see them around June.
