Need massive amounts of storage?
The OWC Mercury Rack Pro Storage Solution is a four bay external mini-SAS hard drive enclosure configured as four independent hard drives, up to a maximum capacity of 12.0TB (3.0TB per hard drive mechanism). 

The OWC Mercury Rack Pro features a single external mini-SAS interface, to not only reduce cable clutter, but to provide four full channels of data (one per drive) through a single external mini-SAS cable.  It's like having four separate eSATA/SAS cables but in a single package.

Designed specifically to meet the demands of server, audio production, and video production environments, the OWC Mercury Rack Pro four Bay 1U Solutions provide data transfer rates of up to 24Gb/s data rates! Using the highest capacity SATA hard drive mechanisms available, and offering Plug & Play simplicity, the possibilities are endless! 

Note: OWC Mercury Rack Pro solutions do not include rack rails. If rails are required for your rack setup, Macfixit Australia has them available. Click Here.

A Top-Notch design using the best components gives the OWC Mercury Rack Pro an industry leading two year warranty and ensures the series is built to last!
