Western Digital introduced its newly redesigned My Book® World Edition(TM) 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 a safe back up. Available now at select retailers and the WD online store, the new dual-drive systems join the recently introduced 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. The My Book World Edition II storage systems ship in Mirrored mode and use half the capacity for file redundancy.
If one drive in the two-drive system ever fails, the system continues to run with the data that is stored on the other drive. 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. With its media server capabilities and fast transfer speeds, this high-capacity system makes it simple to build a centralized digital media library that everyone can easily share.
