WD today introduced its newly redesigned My Book World Edition II dual- drive network storage system in capacities of up to 4 TB.

With the double protection of two Mirrored (RAID 1) drives and continuous backup software, the My Book World Edition II network storage system provides an extra-safe place for users to back up and store the data and digital media from all the computers on their network in one central location. Available now, the new dual-drive systems join the recently introduced (Feb. 2009) My Book World Edition and are compatible with PC and Mac computers.

The My Book World Edition II network storage system uses RAID 1 (Mirrored) technology to automatically and continuously maintain a second copy of user's data. If one drive in the two-drive system ever fails, the system continues to run and the data is safe. In addition, the new My Book World Edition II network hard drive includes software that simplifies the task of setting up automatic and continuous data backup for all the PCs in the home. The My Book World Edition II storage systems ship in Mirrored mode and use half the capacity for file redundancy.

Music, photos and videos can be streamed directly from the My Book World Edition II storage system to any PC, Mac or connected DLNA media player (such as TVs, Microsoft Xbox 360 and Sony PlayStation 3 game consoles or wireless digital pictures frames) using the integrated UPnP (Universal Plug and Play) media server and iTunes Music server software. Users can also securely access their files from anywhere in the world through the Internet using the free MioNet remote access service included with every My Book World Edition II storage system.

The new My Book World Edition II network storage systems are available now in 2 TB and 4 TB capacities. MSRP for the My Book World Edition II dual-drive storage system with 4 TB is $699.99 USD and 2 TB is $399.99 USD.
