Compatible with Time Machine, G-Technology G-Drive Mobile features 1TB capacity and a 7200 RPM hard drive for quickly backing up digital video, photos, music and documents. The device is bus-powered, so there's no need to carry around an external AC power supply.
Thunderbolt is a revolutionary I/O technology that supports high-resolution displays and high-performance data devices via one simple port and a cable that carries both DisplayPort and PCI Express data. And it’s standard on every Mac.
PCI Express is the technology that links all the high-performance components in a Mac. And it’s built into Thunderbolt, which means you can get PCI Express speed outside the box.
Thunderbolt gives you up to 10 Gbps in both directions, allowing for super-fast data transfer between peripherals. You also have enough bandwidth to daisy-chain multiple high-speed devices without using a hub or switch.
Thunderbolt also provides double the power of USB 3.0, delivering 10 watts to peripherals for improved performance on the go.
