About Western Digital

The WD My Book Studio 4TB External USB 3.0 Desktop Hard Drive works out of the box with your Mac OS X 10.6.5 (or later) machine. With data transfer speeds up to 5Gbps, you can move large high definition media files when connected via the SuperSpeed USB 3.0 port. My Book also provides USB 2.0 backward compatibility so your legacy devices won't be left behind.

Built with an anodized aluminum enclosure, the drive is designed to run cool and quiet without a fan. WD SmartWare software comes included with the drive as well, allowing you to install as much or as little of the software as you would like. These can include backup options, diagnostics and utilities. The drive also does its part to conserve energy with its WD GreenPower Technology, which lowers the internal drive's power consumption.
