Summary: This unit does not support RAID 5 over all 8 drive bays, but rather it supports RAID 50 - RAID 5 over 2 groups of 4 disks and RAID 0 over the 2 groups of 4 disks. This results in capacity of 6 hard disks, not 7.
Summary: Very easy to setup. I would recommend to anyone that understands RAID environments. The manual requires the Hubble Telescope to read the small print. A disk that comes with it has a Quick Start Guide but it is for a NON-RAID device.
Excellent RAID unit for the price if you can deal with the setup

Summary: I read the documentation thoroughly and still felt a bit uncertain about setting this up but decided to dig right in. In fairness, I would not want to have to write the doc for setting this beast up.
Potentially fatally flawed unless Mediasonic can come up with some good firmware

Summary: The cabinet is nicely made and the controls are fairly intuitive and easy to understand. Installing hard drives is soooo easy. The fan noise is minimal and even adjustable. Unfortunately the USB 3 connection is finicky.
Nothing better for entry level. Spend your money here.

Summary: I've owned this product for 3 years now. I've had 2 disk failures over its course and each time the raid preformed flawlessly in its rebuild. I run the enclosure in a RAID50 with 8x 2tb WD Red Drives. Initially upon buying this product I experienced subpar RAID50 performance.
Summary: I wish I had read ALL the reviews. I wanted to use this with Raid software, however it does not support individual addressable disks. The Mediasonic ProBox version does. I returned this and purchased the ProBox. If you want Raid Hardware support, this is the box you want to buy.
Summary: I have both the non-Raid and Raid versions of this. The USB 3.0 with a Mac has a few minor issues when drives sleep. They tech support is great though, and I use it with my Mac Pro 1,1 (First Gen Intel one) with a Sonnos USB 3.0 card.
