G-Technology's G-DRIVE mobile Thunderbolt/USB 3.0 hard drive is easy to set up and carry anywhere with your MacBook for storing your most important digital video, music, and documents. Inside its sleek, beveled aluminum case is a high-performance 7200 RPM hard drive with a choice of ultral-fast Thunderbolt or USB 3.0 connectivity. It's also bus powered, so there’s no need to carry 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.
