The G-Technology G-DRIVE hard drive is a superb choice for projects on your Mac like digital photography, audio/video editing, and high-speed data backup that involve huge amounts of data. That's because its Thunderbolt and USB 3.0 interfaces can handle enormous traffic volumes. Plus it's plug and play on Mac OS X and ready to use with Time Machine. And G-DRIVE remains cool and quiet thanks to an all-aluminum enclosure with an integrated heat-sink system.
