The Other World Computing Mercury Elite Pro Qx2 Quad Interface 4-Bay RAID Solution offers a convenient enclosure, which affords installation of your own set of four matched 3.5" Serial ATA (SATA I/II) hard disk drives into a stylish RAID enclosure that supports data transfers up to 3.0Gb/s. The Qx2 is equipped with a custom Oxford 936 Chipset that's compatible with eSATA, FireWire 800, FireWire 400 and USB 2.0/1.1 connectivity. The single eSATA port offers the fastest data transfer rates, up to 3.0Gb/s or 300MB/s. The dual 9-pin FireWire 800 ports facilitate 800Mbps or 100MB/s transfer rates, while the 6-pin FireWire 400 interface supports transfer rates up to 400Mbps or 50MB/s. The USB 2.0 port, which is also backwards compatible with USB 1.1, supports up to 480Mbps or 60MB/s transfer rates, as well as 12Mbps or 1.5MB/s USB 1.1 transfer rates. Supporting four different interfaces ensures that you'll achieve the fastest data transfers possible on your PC or Mac. Plus, by offering a USB 2.0/1.1 port, eSATA port, dual FireWire 800 ports and a FireWire 400 port, all your interface needs are covered and as an added measure of convenience, all supported interface connector cables are included.
Besides offering quad connectivity, the Qx2 also supports user selectable Hardware RAID settings. With the help of a front panel selector switch, the Qx2 enables easy configuration of NRAID, RAID 0, RAID 1, RAID 5 and RAID 10. This allows you to select the best combination of speed, capacity, redundancy or any combination of all three. NRAID (Span) combines capacity of two or more drives of equal size into one volume, as well as combining the capacity of varying size drives based on the lowest capacity in the set. RAID 0 (Stripe) means that data is split into blocks over two or more drives at the same time for high-speed and large capacity. RAID 1 (Mirror) allows data to be written at the same time to two drives for the highest level of data safety and redundancy. RAID 5 (Stripe with Parity) is similar to RAID 0; data is striped while incorporating redundancy over three or more drives for the best combo of speed, capacity and redundancy. Like other quad interface, 4-bay RAID solutions, the Qx2 is pre-configured as RAID 5. Finally, RAID 10 ensures that data is striped over two mirrored sets of drives for fast redundancy.

i have had several backup solutions but this one is the easiest to use and built like a tank - i am running 4 3tb Hitachi deskstars (9tb with parity) and they are VERY VERY quick using eSATA - i use it with firewire as well and it is maxed out on the read write for that as well. - ROCK SOLID! only thing i can look forward to is a thunderbolt version of this (or another version with SATA3 (6GB) connection. OWC is always at the bleeding edge of mac tech but their process of testing is second to none in my opinion. you can be pretty confident that when they bring a product to market it has already been throughly tested for bugs etc. (i have RAM and SSD drives as well and their quality is evident throughout their lineup.)

The Mercury Elite Pro Qx2 is in fact compatible with 4TB hard drives. The units that I bought from B&H on 3/26/12 were not however. After a week of testing and hours on the phone with tech. support we finally concluded that the Qx2s that I purchased were older units and simply would not work properly with 4TB hard drives. I ended up returning the Qx2s to B&H (which they too back without question but it did cost me $35.00 to ship) and bought directly from OWC.
Once I received the the new units from OWC and tested them they appeared to be working quite well. Both Qx2s have four 4TB hard drives in them and are set up for a RAID 5. I ran some speed tests and then actually pulled a drive to simulate a disk failure. I replace the hard drive with a new one and within 12 hours the RAID completely rebuilt itself and I was back up and running. Great. Then, several days later, my computer froze up and I ended up having to manually power everything down. When I fired it back up my Qx2 was rebuilding itself for no apparent reason. I let it work for a couple days before calling tech. support. They couldn't tell me why the unit was rebuilding itself or why it was still rebuilding after 72 hours. They said that with four 4TB hard drives, 4-5 days would be a typical rebuild time..... Hmmmm. That didn't seem to go along with my test results....
So here I am. 12 days later. The unit is still rebuilding..... I'd call tech support again but OWC tech support was barely helpful at best. I'll probably need to reformat my drives and move my 6TB of video back over to it..... Anyway, I gave the Mercury Elite Pro Qx2 one star for these reasons and several more that I didn't even list here. It would take me two days to explain all the little hiccups I've had with these. Thanks OWC.
I should also note that I have had these units connected to my Mac Pro via eSATA. I didn't seem to have any major problems when connecting via firewire 800 although testing was limited.

Comments about OWC / Other World Computing Mercury Elite Pro Qx2 Quad Interface 4-Bay RAID Solution:
It's more of a hardware solution than I thought. I had planned to install 'in use' twinned drives and reduce the 'footprint' of my hard drive village … I thought the drives would show up separately and I would use a software solution to twin the data ... no, it wants to initialize the drives … so where do I put a few TB of data while I initialize the drives … I also bought a 1.5TB WD to twin with one I already own … only to find it not recommended for this device … it could be me, maybe I should have realized it best to start with empty drives or have a plan to move data off and on existing drives … but the 'not recommended' drives should be mentioned in the description … it could be good when I figure this out ...

Bought this product to have an offsite backup of my Pegasus RAID. Put 4x3TB drives into the unit and adjusted the onboard switch to the RAID level I desired, connected it via FW800 and it immediately showed up in Disk Utility. Has great transfer speeds via FW800 (was averaging about 100MB/s). Have not had a chance to test it via eSATA yet. The on board fan is also very quiet.

Booted right up, no setup necessary. Running 4 3GB Seagate's in it which gives out roughly 8.5GB in RAID5.
Very satisfied so far!

Comments about OWC / Other World Computing Mercury Elite Pro Qx2 Quad Interface 4-Bay RAID Solution:
Simple to setup and configure. Came pre-formated for Raid 5, which is what I needed. I put 4x 2TB WB Caviar Black drives in it. This is a great, solid system that offers me peace of mind. This is my first raid system and I am very happy with my choice. The fan was a bit louder than I expected, but ultimately that has not been a huge issue for me.

Comments about OWC / Other World Computing Mercury Elite Pro Qx2 Quad Interface 4-Bay RAID Solution:
I'm currently using this with 2TB Hitachi SATA drives in RAID5 and Firewire 800. It's maxing out the firewire speed, and in regular use the fan is nearly silent. I wish it had a Thunderbolt interface as well, but at this price that would be a little unrealistic. The only speed limit seems to be the Firewire bus, haven't tried to fail a drive and see how fast a rebuild happens.

Comments about OWC / Other World Computing Mercury Elite Pro Qx2 Quad Interface 4-Bay RAID Solution:
I have been looking for a standalone Raid system of this caliber for a long time and forever it has been over $2,000, if not more. Now, with OWC, I can have a Raid-5 9TB partition that is rock solid. With eSata and other connectors to interface, I can hook it up to almost any computer with very quick transfer speeds.I bought one to test the waters and have already placed an order for several more. I love this product.

Comments about OWC / Other World Computing Mercury Elite Pro Qx2 Quad Interface 4-Bay RAID Solution:
It is the fastest & most versatile 4 bay enclosure we've seen.
Esata interface screams, and it takes just 15 minutes to install 4 drives and get going. It is set up out of the box for fast RAID5, so just most people will just get 4 of their favorite 3tb drives (they should all be the same), and suddenly you'll have a 9tb usable RAID system.
It's made of heavy gauge metal, so it's not light.
So far it just works like you'd expect.
If you want maximum performance on a macbook, you need to have an express/34 slot and eSata adapter card ($20-40). WIth an older 15 or 17" macbook with the express/34 you really don't need thunderbolt. This is cheaper than any similar thunderbolt device and almost as fast.

Comments about OWC / Other World Computing Mercury Elite Pro Qx2 Quad Interface 4-Bay RAID Solution:
Like that it supports RAID 5 out of the box with an option to use 3 disk RAID 5 keeping the fourth drive as an extra safety swap in. Well built, easy to use and fast enough for video work. Only drawback is that it won't support JBOD if you want to connect multiple drives through one esata port. If it did support that, I'd give it 5 stars.

Comments about OWC / Other World Computing Mercury Elite Pro Qx2 Quad Interface 4-Bay RAID Solution:
This OWC product is solidly built, easy to configure, and operates very quietly. All of the OWC products that I have ever used are built extremely well. This included. This 4-Bay RAID system is flexible and allows you to configure with multiple back-up options. You just pick the balance between big HD space, fast write to disk, and safety of backup based on the descriptions in the manual and you are all set. Comes with multiple ways to connect to your computer. AND they supply ALL the cables that you need for EVERY connection solution.
