OWC's Mercury On-The-Go family of pocket-lovin' hard drives has been around for quite some time, but the group is getting an all new leader courtesy of the recently announced 500GB edition. Packing a half-terabyte of space on a 5,400RPM, 8MB of cache drive, the unit even includes FireWire 800, FireWire 400 and USB 2.0 to ensure compatibility with pretty much whatever rig you're dealing with. You'll also find a copy of Prosoft DataBackup III for OS X and NovaStor NovaBackup for Windows bundled in, but you won't be getting any closer to this bus-powered unit than the photo above without laying down $359.99 to call one your own.
