TECHNOLOGY REVIEW: Western Digital My Book Mirror USB 2.0 external hard drive
The Western Digital MY BOOK MIRROR EDITION is a USB 2.0, two-drive external hard drive storage device. Drive can be configured as either RAID 1 (for duel data backup) or RAID 0 (for full 2-drive storage capacity). The My Book Mirror comes preconfigured for RAID 1 in capacities up to 2TB. It is designed with user replaceable hard drives, but it should be noted the My Book Mirror only supports Western Digital brand drives. Overall good performance. Comes with a three-year warranty and useful bundled backup software. 3 Stars.
