USB and SSD on a device that looks like a USB flash drive? The Buffalo SHD-LVS-BK USB SSD is powered via a USB 2.0 port and holds 64GB of data. And it measures just 23mm x 10mm x 98 mm. Buffalo has even incorporated a switch to help prevent accidental deletion of old files as well as stopping new files from being written onto the drive. That will be handy.
It also boasts TurboPC and TurboCopy functions to boost transfer rates. You can choose from 3GB, 8GB, 16GB, 32GB and 64GB capacities for $28, $45, $77, $135 and $260.
