Sleek aluminum enclosure complements your Mac.
The premium, aluminum enclosure matches your Mac and remains cool to the touch even as the drive delivers blisteringly fast performance.

Designed for the Mac professional.
Formatted for Mac, this drive is plug-and-play ready for Mac computer users. It's ideal for videographers, photographers, video editors and other graphic professionals.

Heat-dissipating, aluminum enclosure.
Encased in a streamlined aluminum enclosure that remains cool to the touch, this drive complements your Mac and as always, takes up minimal space on your desk. The book-like design allows two or more My Book drives to nestle neatly together like volumes on a shelf.

Password protection.
Gain peace of mind knowing that your data is protected from unauthorized access or theft with password protection and -bit hardware-based encryption. (Requires WD SmartWare software.)

Runs cool.

The drive is designed to run cool without a fan. Lower operating temperatures extend the life of the drive and improve data reliability, while the fan-less design reduces noise output.

Power miser.
My Book external drives are designed to save energy. WD GreenPower Technology lowers internal drive power consumption by up to 30%, a sleep mode reduces power during idle times, and a power-saving feature turns the drive on and off with your computer.
