WD today added a high-speed FireWire 800 interface to its My Passport Studio portable drive. With FireWire 800/400 and USB interfaces, the new My Passport Studio portable drives offer up to 500 GB of storage capacity, are formatted for Mac computers and weigh less than 7 ounces.

A built-in, illuminated capacity gauge tells users how much space is available in the drive and because it is powered by the FireWire or USB connection, it is truly portable. In addition, My Passport Studio can be used to backup Mac laptops using Apple's Time Machine application.

Available now at select retailers and at WD's online store (www.shopwd.com), MSRP for My Passport Studio with FireWire 800/400 interfaces and 500 GB capacity is $249.99 USD; MSRP for 400 GB capacity is $229.99 USD.
