## Description

Product Description OWC Mercury Elite Pro Dual Performance RAID Enclosure Mac / PC / USB3.1 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.

A second-generation, free-flowing brushed-aluminum chassis with high-performance fan delivers cool, quiet operation.

Review: Great device - but a little fiddly to setup compared to my Akitio units. - It is currently running 8TB as JBOD for duplicate backups, and does the job well. If you need a USB attach raid storage then this is a good cost effective option. I have two Akitio units which I would have preferred, but they appear not to exist now.

## Questions & Answers

**Q: Does this enclosure work with ssd (solid state drives)?**
A: Hello! Yes this enclosure will work with SSD's. However they will not fit in the drive bays without the use of a 2.5" to 3.5" adapter Bracket. We recommend the Newertech Adaptadrive (found here: http://a.co/8beqOas) for situations like this.

**Q: In raid 1, if one drive fail and after the failed drive is replaced, can this enclosure rebuild its raid 1 without being connected to the pc?**
A: Hello.  This enclosure would need to be connected to a computer in order to properly power on and rebuild the RAID after a failure.

**Q: If one drive fails, is it as easy as just pulling the failed drive and adding a new one if configured in Raid 1?**
A: Yes - though pulling involves powering the unit down and disassembling it, especially if the failed drive is in bay #1. It no longer matters which bay the new drive is in - the unit will rebuild to the empty drive. 
This is a huge improvement from their older RAID units where the good drive had to be in bay 1 because it copied from bay 1 to bay 2 no matter regardless of which was the empty drive.

**Q: I am considering this enclosure to set up two 6 tb hard drives on raid 1. which would you recommend: western digital black, blue or red drives?**
A: All versions should work paired in the enclosure, but are rated for different applications.  Black is the higher performance drive: Video work and higher access speeds at 7200rpm.  Red is for long life in constant "trickle" streaming as in security, or for building a NAS, at 5400rpm.  Blue is for general "consumer" storage applications at 5400rpm.  There is also a Purple that is specified for security video use, but I usually use Reds for that application due to availability.

### ⭐⭐⭐⭐⭐ Great device - but a little fiddly to setup compared to my Akitio units.
*by N***K on 12 August 2024*

It is currently running 8TB as JBOD for duplicate backups, and does the job well. If you need a USB attach raid storage then this is a good cost effective option. I have two Akitio units which I would have preferred, but they appear not to exist now.

### ⭐⭐⭐⭐⭐ Muy buena caja!

Muy buena caja!

### ⭐ Not worth it - useless.
*by K***R on 2 March 2025*

Stopped working ('the disk structure is corrupted and unreadable') less than two months after installing. This kind of device should be of the 'set it up and forget it' kind. If you can't trust it to work properly, it is quite simply useless.
