Plextor helpfully tries to save you from yourself with its PX-SP portable hard drives, swathed in cushy silicone to protect them from life's little accidents. They're bus-powered via USB 2.0, and available in capacities of 80GB and 120GB.
Comparable to slip covers on a vinyl couch, the drive's protective silicone surface is protected with a little black carrying case. Hey, anything to save that precious data.
