Western Digital has added a pair of new external storage drives to its Mac product line. The company now offers 750GB and 1TB iterations of the My Passport SE. Aimed specifically at Apple computer users, the drive comes formatted for Mac systems, and Western Digital says it's compatible with Apple Time Machine software.

The My Passport SE drives are highly portable, as they are powered by USB 2.0, eliminating bulky adapters. The drives also measure only 0.70 x 4.3 x 3.2 inches, weigh less than half a pound, and are equipped with 256-bit hardware encryption with password protection to keep your data secure while on the move.

The My Passport SE for Mac external drives are available now through Western Digital's online store. The 750GB version ships for $179.99, while the 1TB unit is $199.99.
