Western Digital (http://www.wdc.com/en/) says its newest generation of the My Book Studio external hard drives for use with Macs and Apple’s Time Machine, are now available with a 3TB storage capacity.

What’s more, the new design features a brushed aluminum casing to match the appearance of a Mac and 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 and extend the life of the drive. 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 1TB, 2TB and 3TB, 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 (http://www.wdstore.com) and at select retailers and distributors. The manufacturer’s suggested retail price for My Book Studio with 1TB is $149.99; MSRP for My Book Studio with 2TB is $199.99; MSRP for My Book Studio with 3TB is $249.99.
