The OWC / Other World Computing Mercury Rack Pro 12TB (4 x 3TB) Four-Bay 1U Rack SAS Storage Solution comes with four 3TB hard drives that provide a total storage capacity of 12TB for your workstation. It connects to your system via the single mini-SAS port and the included 3.3′ mini-SAS cable. When used with a separately sold external mini-SAS card, the Mercury Rack Pro offers drive transfer rates of up to 24 Gb/s.
The 3.5″ drives spin at 7200 RPM and have 64MB of cache per drive, 256MB total for the solution. You may configure these drives into a RAID array that delivers data performance, redundancy, or a combination of both. For cooling, the Mercury Rack Pro sports three quiet 40mm fans that spin at a constant speed. Furthermore, the flexible form design allows you to convert the Mercury Rack Pro Storage Solution to a desktop form factor using a Phillips screwdriver, and simply removing the rack ears and installing the included anti-skid, vibration-dampening feet.

This is a great RAID array at an affordable price. It is very flexible for any system. This is a part of a new Mac server setup in a large Church. Setup using RAID 5 which allows access to 9TB total. Plan to buy another one of these as a dedicated Time Machine RAID for all the Mac’s in our office.

The drive arrived with all advertised gear and worked upon plugging in. After 1 weekend one of the 4 drives failed. I called Customer Service of both B&H and OWC, and both were quick to help solve the problem. I cannot complain about a hard drive failing, as unhappy as I may be, but the company helped resolve the issue quickly and professionally.
