Pros: With up to four x 2TB drives installed this unit offers great storage capacity. Setup is fairly easy , and you have two connection options (USB 3.0 and SATA). There are lots of bright lights when the backup is running. And, the ability to run RAID+O is great, and provides a backup of the backup, when the drives operate as intended (see cons).

Cons: The usint, using a USB 3.0 connection and Windows 7, seems to lose it's drive recognition often. If I power the unit down and then repower it the drive comes to life and True Image begins to run its backup. But this is hardly providing peace of mind when I have client data to regularly backup.

Overall Review: I would recommend this, especially if I could figure out how to insure the drive was always recognized and my automated backups were happening consistently.
