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.
