Do you demand portability from your Redundant Array of Independent Disks? Then you’ve probably already seen Sonnet’s Fusion F2 , with its two 1TB drives and eSATA connector. Today the company introduces the Fusion F2QR, which also features two 2.5-inch, 1TB hard drives — but now comes with four interface options. You’ve got your eSATA, of course, but also Firewire 400, Firewire 800 and USB 2.0 connectors. There’s a new built-in RAID controller that smooths configuration as well, and the aluminum case and fanless design keep noise to a minimum. All of that fits in a shell measuring 5.9- x 6.1- x 0.95-inches. This slender slab of storage is available now and will set you back $569. Need RAID?
