WD today introduced its new My Book Mirror Edition dual-drive storage systems, which can automatically store personal content not once, but twice, to maximize data safety. This RAID-based continuous data protection feature, called mirroring, makes WD's My Book Mirror Edition storage systems the safest place for storing irreplaceable data.

When users store their personal content on a My Book Mirror Edition system, their data is automatically mirrored for extra protection.

Consumers can also use the My Book Mirror Edition storage system and the included backup software to automatically and continuously back up their personal computers.

Formatted for Windows computers, these new storage systems feature a USB 2.0 interface, they are configured out-of-the box in RAID 1 (Mirrored) mode [RAID 0 (Striped) configurable] and they are available in capacities of up to 1 TB and 2 TB.

The drives also consume approximately one-third less power than standard dual-drive external storage systems.

My Book Mirror Edition dual-drive storage systems are available now. MSRP for My Book Mirror Edition with 1 TB is $289.99 USD; MSRP for My Book Mirror Edition with 2 TB is $549.99 USD.
