Install your own set of four matched (same part number) 3.5" Serial ATA (SATA I/II) hard disk drives into this brushed aluminum enclosure with Hardware RAID setting flexibility and experience up to 300MB/s data transfer speed for high performance data storage and redundancy.
Span
Thanks to a front panel selector switch, the Mercury Elite Pro Qx2 enables easy configuration of the hardware RAID settings to Span, 0, 1, 5, 10, and JBOD/Independent drive modes – so you can select the best combination of speed, capacity, redundancy.
RAID 0 (Stripe)
Combines the capacity of two or more drives of the same size without any RAID data distribution scheme into one logical desktop volume. This mode can combine the capacity of varying size drives based on the lowest capacity drive in the set.
RAID 1 (Mirror)
Data is split into blocks over two or more drives at same time for high speed and large capacity. The ideal RAID setting for demanding video production/editing.
RAID 5 (Stripe with Parity)
The same data is written to two drives for highest level of data safety and redundancy.
RAID 10 (1+0)
Data is Striped (RAID 0) while incorporating redundancy over three or more drives for the best combination for speed, capacity, and redundancy. The Multi-Interface 4 Bay Enterprise Class Performance RAID Solutions are pre-configured as RAID 5.
JBOD/Independent drive operation
Data is Striped (RAID 0) over two Mirrored sets (RAID 1) of drives for fast redundancy. Each drive mounts as an individual volume.
Bought this back in 2010 for film and video editing. Configured it as a RAID-5, through a eSATA-to-Thunderbolt adapter, to my iMac. I kept it on essentially 24 hours a day during that time, never had a drive failure. About once a year I'd take time to blow the dust out to make sure airflow was always good.
Worked flawlessly for about 7 years. In the 7th year, I started getting strange behavior. Beep codes randomly which couldn't be identified in the manual. Randomly wouldn't mount after booting some times, and in the final days it would take dozens of power-ups to get it up. As soon as I started having these problems, I checked my purchase and of course I was just a few months over my warranty. Ugh, oh well. I LOVED this little hardware RAID box. 7 years was a great run, but I'd be lying if said I wasn't a little disappointed in the longevity. The point of having a RAID box is for data reliability. I expected to lose a drive, but I never did. However, I never expected the hardware itself to fail.
My Mercury Elite Pro SATA Desktop RAID Enclosure is a great low end RAID box. It is missing the ability to alert you if one of the drives fail so it should be used in a home or an environment where someone can see the front end of the box everyday. It is fast and with 6TB HDDis kicks butt and takes names. It is my fault I did not research this product better and I bought two of them so I guess I better love them as most devices from OWC run 6 to 7 years before I pitch them to buy the newer stuff.
I would recommend this product to a friend!
Verified Purchase.

Thank you very much for the feedback on the Elite Pro QX2! With the hardware controller for the RAID, there's not a good way to get software involved and notify of a hard drive issue. We did just come out with the Elite Pro Quad, which now uses SoftRAID to control the RAID. This allows the ability for email alerts and monitoring for all drives on your system.

Great Product!
Easy to set up and configure and works like a charm. I put 4, 2tb, WD pro hard drives from a failed Drobo and only wish I had never bought the Drobo... It is a great value too. I highly recommend this approach if you need big hard drive storage.
