G-Technology 500GB G-DRIVE mobile USB Portable Hard Drive

The 500GB G-DRIVE mobile USB Portable Hard Drive from G-Technology is a portable USB 2.0 hard drive, designed to match the aesthetics of Apple's white unibody MacBook computer. The drive weighs a little more than half a pound and draws power from your computer, allowing you to use it without having to fiddle with AC adapters. It spins at 5400rpm and is formatted as an HFS+ volume for compatibility with Mac OS X and Time Machine. Simply reformat as a FAT32 or NTFS volume if you'd like to use the drive in Windows.
