Sonnet Technologies has introduced the Fusion F2QR, a portable 2TB two-drive storage device with an integrated hardware controller — at $569 it doesn't come cheap, but the controller allows you to move it from computer to computer. The compact FireWire-powered storage system is housed in an aluminum shell and features eSATA, FireWire 800 or 400, and USB 2.0 connectivity, while supporting RAID 0, RAID 1, span, or independent configurations.
