Product Features

The safest place for your data - Using RAID mirroring technology, this system automatically and continuously duplicates your data for the ultimate in data protection. If one drive in this two-drive system ever fails, the system continues to run and your data is safe. How's that for peace of mind? Automatic backup software - Back up your computer - just set it and forget it. Every time you save a change it's backed up and then mirrored on the second drive for the ultimate in data protection. Cooler, quieter, eco-friendlier - Designed to use only WD drives with GreenPower™ technology, this system, with its efficient convection cooling architecture, fan-less design, and power saving mode, is reliably cool, remarkably quiet and consumes up to 33% less power* than standard systems. * Tests based on comparison between a 1 TB dual-drive system using 7200 RPM drives and a 1 TB dual-drive system using WD's GreenPower drives. Easy to set up, easy to use - You're up and running in a few simple steps. WD's intuitive RAID wizard software lets you easily modify your RAID settings. Capacity Gauge - See at a glance how much space is available on your drive. User serviceable - Want to upgrade a drive? Simply open the case and replace the existing drive – no screwdriver needed. NOTE: RAID 0 (striped) accesses the full capacity of the drives. RAID 1 (mirrored) accesses half of the total capacity for data protection.
