WD today introduced its newly redesigned My Book World Edition network storage drive, simplifying the critical but tedious task of backing up an entire household's precious files. Designed for consumers who have multiple computers on a home network, the new drive will be available in 1 terabyte and 2 terabyte capacities, and is compatible with PC and Mac computers.

My Book World Edition network drives are designed to automate and simplify the backup chore for the 36 million networked homes in the U.S. according to research firm Parks Associates. Just plug the My Book World Edition drive into a network router, click a few buttons and the My Book World Edition storage device backs up the files from all the PCs and Macs on the network. Any changes to the files on these computers are automatically and continuously backed up to the drive.

My Book World Edition also allows you to build a shared digital media library. Music, photos and videos can be streamed directly from the My Book World Edition drive to any PC, Mac or connected DLNA media player (such as Microsoft Xbox 360 and Sony PlayStation3 game consoles, wireless digital pictures frames or TVs) using the integrated UPnP (Universal Plug and Play) media server and iTunes Music server software.

The My Book World Edition network hard drives are available now in the 1 TB capacity and expected later this month in the 2 TB capacity. MSRP for the My Book World Edition storage system with 1 TB is $229.99 USD and 2 TB is $449.99 USD.
