Western Digital today announced that its newest generation of the My Book Studio external hard drives are designed for use with Mac computers and Apple Time Machine.

Now available with a 3 TB storage capacity, the new design features a brushed aluminum casing to match the appearance of a Mac computer, and also serves to keep the drive cool while in use. The aluminum exterior, combined with its WD Caviar Green drives, eliminates the need for an internal fan to reduce drive noise. Although formatted for Mac computers, the My Book Studio external hard drives can also be reformatted for PCs.

The My Book Studio external hard drive includes FireWire 800/400 and USB 2.0 interfaces, user-controlled automatic backup software and drive management, password protection and hardware encryption. Shipping in capacities of 1 TB, 2 TB and 3 TB, the My Book Studio drive includes the WD Caviar Green series of internal hard drives with WD GreenPower Technology.

WD's My Book Studio is available on the WD store at www.wdstore.com and at select retailers and distributors. MSRP for My Book Studio with 1 TB is $149.99 USD; MSRP for My Book Studio with 2 TB is $199.99 USD; MSRP for My Book Studio with 3 TB is $249.99 USD.
