How to set up and configure
an OWC Mercury Rack Pro.
Multi-Interface
The OWC Mercury Rack Pro RAID series offers (1) eSATA port with eSATA Port-Multiplier capability, (2) FireWire 800 (1394B) ports, (1) FireWire 400 (1394A) port, and (1) USB 3.0 port for easy Plug and Play on ANY system! The OWC Mercury Rack Pro RAID even includes all needed connection cables!
Swap Drives at Will
When using the OWC Mercury Rack Pro in Independent mode*, all four drives appear on your system as individual volumes drives, so you can mix and match drives of any size and brand and hot swap** the drives too.
Smart Power
Smart Power regulates power during prolonged periods of inactivity to save operating costs and prolong component lifespan.
Flexible Form
The OWC Mercury Rack Pro can easily be converted to a desktop form-factor via a Phillips screwdriver by simply removing the rack ears and installing the included anti-skid, vibration dampening feet.

*When using in independent mode via eSATA, you must use an eSATA Port Multiplier capable card.
Please see "Recommended eSATA Cards" in SPECS table and check for Port Multiplier compatibility.

**When using in Independent Mode and wanting to switch out one or more drives, ALL drives must be ejected (unmounted) from the Desktop to avoid data corruption. 
From day one, the OWC Mercury Rack Pro Series has been designed to be everything you'd hope for and more!

OWC RAID Manager (BETA Version*)

Control and manage your RAID settings with this easy to use visual interface.

The power of simplicity is evident in the OWC RAID Manager. With easy to follow options and menus, this convenient user interface adds a level of control and monitoring for unrivaled operating confidence.

*While the functionality of the user interface is nearly complete, the overall look and feel as well as basic environment settings (dock and menu bar item) are still being finalized. As such, this product is in a BETA level of support and therefore no guarantee of system stability, data integrity, etc. is offered. For more information, please read the Software License Agreement here.

Please note: OWC RAID Manager is not compatible with OS X 10.10 or later.

Qualified Hard Drives

Serial ATA drive models OWC has tested and qualified for use with the Mercury Rack Pro:

A 'recommended' drive is one that, through our extensive and ongoing evaluation process, we've found to have optimum operational characteristics required for demanding RAID applications.

Note: OWC is always testing new drive models and adds additional models as they become available and have passed our stringent requirements. If you do not see a new drive model listed, please check back in the future for confirmed OWC Mercury Rack Pro Qualification.

Note: Regardless of drive model used, OWC recommends all drives used in RAID configurations match exactly for proper RAID operation.

**NOT RECOMMENDED**
  • Seagate Barracuda 7200.11 series - all models, particularly the 1.5TB 7200RPM model p/n ST31500341AS due to stability and performance concerns.

Rating: 5/5 Great external storage solution that looks nice too October 10, 2017 I have used this Rack Pro for a few weeks now with no issues whatsoever. I chose this enclosure because it has plenty of options for RAID setup and for I/O, as well as the form factor for a 1U rackmount setup. I already own a 12-bay synology NAS, but wanted something that would connect directly to my Macs as an alternate backup. Installed new hard disks, turned the Rack Pro on, followed the supplied instructions for formatting, and was up and running quickly. Everything has run smoothly and without any problems since then. It's nice and quiet in the rack. The only way I think it could be improved is if it was offered in a redundant power supply configuration.

I would recommend this item to a friend! Customer Videos:

Rating: 5/5 Excellent CCTV/NVR Solution January 27, 2017 I'm the OPS & Applications Manager for a systems integrator in South Georgia. We use a lot of these Mercury Rack Pro units for storage array's on NVR's we build in-house. Paired with an economical 1U server chassis, the Mercury makes a formidable storage mechanism for custom CCTV solutions. With properly sized HDD's, you can accommodate several dozen HD IP cameras for 2-3 weeks. We like the RAID versatility, the reasonable price, and the ability to use USB3.0, eSATA, or SAS (if you choose the SAS model). The Mercury also makes an excellent choice for a backup location for video editing. I might would advise one of the newer ThunderBay units for pro-grade NLE, but the Mercury works well as an option for a safety net.

I would recommend this item to a friend! This review is from 8.0TB OWC Mercury Rack Pro 4 Bay eSATA, FW 800, FW 400 & USB 3.0 1U Rackmount Hardware RAID. Customer Videos:
