Mercury Elite Pro Dual
20.0TB Performance RAID Solution

Mac / PC / USB3.1 Gen 1 / eSATA
With USB 3.1 Gen 1 & eSATA
Professional Grade Solution
Mercury Elite Pro Dual is the best dual-drive hardware RAID solution for creative workflows, project archives, and system backups where reliability and versatile performance count. With two fast hard drives, easily configured in multiple RAID modes at the flick of an easy-access switch, Mercury Elite Pro Dual is built to seamlessly integrate with any work environment from high demand production studios to your home office.
The Hardware RAID Workhorse
Reliable hardware RAID maximizes the full potential of two 3.5" 7200RPM hard drives in the Mercury Elite Pro Dual. It comes configured in high-speed RAID 0 mode for the maximum sustained throughput from your drives. With speeds up to 407MB/s, that's fast enough for HD video workflows. Configure the Mercury Elite Pro Dual in RAID 1 mode for the extra security of mirrored data, set up a span of the two drives, or use them independently.
Performance by Design
Mercury Elite Pro Dual features both high-speed USB 3.1 Gen 1 & eSATA ports to offer the connectivity and versatility to work with your current equipment at extreme speeds. A second-generation, free-flowing brushed-aluminum chassis with high-performance fan delivers cool, quiet operation. In addition, drive-activity LEDs give you an instant snapshot of the status of your RAID, and intelligent power management conserves energy and reduces wear by automatically spinning down the drives when inactive.
Support You Can Trust
Like all OWC products, Mercury Elite Pro Dual is built to the highest standards from design to delivery. Each unit undergoes rigorous lab testing for exceptional performance and reliability. It's also always fully backed by a comprehensive warranty and our legendary US-based customer support team.

Rating: 5/5 I am so pleased April 12, 2018 There was an issue with this drive - it kept on ejecting from my iMac Pro but a call to your support team and the problem was solved. The drive is super fast and I just love it. It is exactly what I wanted and better yet expected. This is why I buy from OWC.

Rating: 5/5 Great Raid enclosure April 8, 2018 I was looking for an enclosure for two identical bare drives and saw this one. I ordered it and it came in a few days. Popped in the empty drives, set it for RAID1, powered it on and in a few seconds it was ready to go. Attached to my MBP via USB3 and put it in service. It's been brilliant in operations, with a simple set of lights on the front to tell you about the stats of the drives. The LEDs are a bit bright, so I've turned the drive to one side to avoid having them directly in my eyes. The cooling fan is also audible above the quiet of my office, but I've put an old mouse pad under the feet and the noise is less noticeable. Other reviews have referred to the noise, but it isn't intolerable, just louder than anything else in the setup.

Rating: 5/5 Great enclosure to revive spare drives March 25, 2018 I bought this to turn two 3TB G-Tech drives that were collecting dust into a 6TB RAID 0 drive that I can use to edit off of. So far it's worked wonders. Great quality enclosure and I'm happy with the sturdy quality of the enclosed cables.

Rating: 5/5 Quality enclosure; many RAID choices. March 21, 2018 I chose this enclosure to house a pair of drives I wanted to mount independently, and it will do that, however I could easily chosen one of three RAID options via the switch on the back. The quality of the machined aluminum enclosure is a rarity in these days of plastic. I have it hooked up to a USB 3.0 PCI card on my MacPro, but will probably hook it up to eSata if a port frees up. Very pleased.

Rating: 5/5 Quiet and fast March 3, 2018 I purchased this enclosure to set up a mirror RAID as a second backup for my digital photo files. I installed a pair of 4Tb HGST drives. It is very quiet in operation and with my eSATA connection on my old, upgraded MacPro, is very fast to handle these big files. Recommended.

Rating: 5/5 meets my needs easily and quickly November 26, 2017 Have installed two enterprise 3 TB drives and the unit is functioning as expected. Fan is a little noisier than I anticipated but that may only be a result of using it in a quiet office on a glass desk. High quality packaging and fast shipping as one would expect from OWC.

Rating: 5/5 work's like a charm March 26, 2017 My buying experience at OWC has be really good. I've had questions and concerns that over the years they have been responsive to and very helpful with. My latest purchase, this 6TB external drive has worked like a charm out of the box. It's speed is eye opening. I'd buy it again if I needed more storage. Great place to buy with great support.

Rating: 5/5 Nice, cheap RAID enclosure March 15, 2017 Easy to set up hardware RAID. The only thing I'd like to see is the instructions for changing the RAID setting printed on the enclosure somewhere as I'll never remember them and have to look it up on the website or save the instruction pamphlet. It's a sequence of a mode selector, power and a reset button--and I've already forgotten it. Most users will probably set it once and never need to change it, so maybe it's just me.

Rating: 4/5 Great case! December 22, 2016 Great, well-built case. I purchased it with no drives. Adding the drives was a little annoying because the rubber feet included by the screw-holes on the case wanted to slide around with pressure, so it took some finagling to get them in. Once they were in, though, reassembly was a snap and had no further issues.

Only negative I can see is the lack of management software - there's no way to query individual drive SMART status, for example, even with an included tool or open source software like smartctl.

The Fan is wonderfully quiet.
