The Mercury Elite Pro Dual Multi-Interface Performance RAID Enclosure Kit from Other World Computing houses two user-supplied drives that can be easily configured in RAID 0, RAID 1, span, or JBOD (independent) modes via the RAID selector switch on the back. The Mercury Elite Pro Dual also has two Thunderbolt ports as well as a USB 3.0 port to provide fast access to your data. The Mercury Elite Pro Dual features a durable, heat-dissipating, brushed-aluminum enclosure and it is compatible with Mac, Windows, and Linux computers.

High Performance
The high-speed Intel "Cactus Ridge" chipset, combined with some of the fastest SATA drive mechanisms available, gives the Mercury Elite Pro Dual the ability to reach single-drive transfer rates of up to 1250 MB/s (via Thunderbolt)
Portability
The compact and shock-resistant design of the Mercury Elite Pro Dual offers two Thunderbolt ports and one USB 3.0 port for high-speed data transfer rates. The OWC Mercury Elite Pro Dual even includes all needed cables
Smart Sense
A built-in, power-saving connection sensor detects when the data cable is disconnected from a Mac or PC's native Thunderbolt or USB interface and automatically spins down the drives to conserve energy during periods of inactivity. This is also ideal for notebook users who can go mobile without the need to turn it off or unplug the power cord. For RAID 0 or RAID 1 functionality, it is recommended that identical drives be utilized. This function is also available through an interface card, provided the card offers hot plug capability. LED and fan will remain on during disk inactivity

      This is a fast, beautifully built drive enclosure. It does as it says, very well.
      It could be better in two ways:
      1. It's too expensive for a drive housing.
      2. There has to be a better, simpler, more elegant way to swap drives out. 12 screws in total? It's build like a tank, but no one is dragging their drives behind a 4x4. What I'm doing is swapping drives out frequently, and screwing, unscrewing, losing and dropping screws . . . the method is arcane.

          For thunderbolt or USB 3 its about as good an option you can get for so little cash.

          One issue I had it with the way the drives mount. You push the lower one into a circuitboard, and the upper uses a cable. This means that you cannot use smaller drives, like SSDs with it. Not the best system.

            Comments about OWC / Other World Computing Mercury Elite Pro Dual Multi-Interface Performance RAID Enclosure Kit:

            I'm a huge fan of OWC products. This unit came as a casing, so i manually installed two SATA drives, installation was straightforward and easy, you just need a small screwdriver.

            The best part of this unit is that it made it possible to easily move the sata drives from my legacy mac pro to a clean looking thunderbolt external drive. It's fast enough to use for all my HD footage, and has been very reliable.

            NOTE: There is a switch on the back to set the raid type. If you are installing drives that already have data on them, make sure the switch is set to INDEPENDENT or else the unit will erase them, and you will have to go through a laborious data recovery process.

              Comments about OWC / Other World Computing Mercury Elite Pro Dual Multi-Interface Performance RAID Enclosure Kit:

              So far, I have been impressed with this enclosure. I've got a couple 2tb Seagate Barracudas in it set up as RAID 0 and I am getting write speeds of around 300mb/s and read speeds of around 360mb/s so that's pretty good. It has been stable and solid over Thunderbolt. I haven't had it eject randomly or fail to show up on the desktop so that is super important. Really, the only downsides I have found yet to this thing is that there is no power switch so it's just always on or off depending on what your computer is doing. I prefer to have manual control of turning it on or off but it's not really that big of a deal. Also, the fan can be a little loud as most people have said. I started with it on the top of my desk and quickly realized it was too annoying there so I just moved it under the desk and I barely even notice that it's on now. So, again, a little annoying but not really a deal breaker for me. Overall, I am satisfied with this so far and it has been stable with good performance which is the most important things for me. I would recommend this if you need a simple, cost effective, Thunderbolt RAID...

                    Comments about OWC / Other World Computing Mercury Elite Pro Dual Multi-Interface Performance RAID Enclosure Kit:

                    The enclosure was a lot smaller than I anticipated being marginally taller than the hard drive (excluding the feet which still aren't that big) and about one and a half hard drives deep. The RAID mode is a breeze by using the switch on the back to change modes. After making a selection just plug it back in and on a Mac, just choose disk utility to format the drives in the chosen setting and away you go. The speed was quite surprising from a Retina Macbook Pro with SSD to the drive. About a second for a 230mb file copying across. To copy my entire external USB 3.0 hard drive across to the enclosure only took 4 hours for 1.4TB. That's while having the Mercury in RAID 0. The speed test also revealed about 270mb/s read and similar write via thunderbolt. The same can't be said for a USB 3.0 drive reading only 120mb/s or thereabouts. This enclosure is simple, effective, fast and quiet. It also powers down when I disconnect my Mac and powers right back up when I connect it again. The fan hardly can be heard and I have this in a relatively quiet office on my desk. Overall a fantastic product. So much so I may buy another in the future to have a back of the original.

                            I needed external storage for my new Mac Pro (which has almost none internally), so I chose to get two of these enclosures. I put in 2 4TB drives in each, used the hardware RAID 1 setting to mirror each duo, and then I striped them in RAID 0 using Disk Utility to get both speed and reliability. I can lose a drive in each and still be ok. I put Hitachi Deskstar NAS drives inside for better reliability. I only wish it had Thunderbolt 2 and the fans aren't super quiet. Build quality is bulletproof though.

                              I have two 4TB WD Caviar drives in the case and have used them as a Raid and individually for multiple video projects. Very versatile. I padded the feet to eliminate drive noise, but that is coming from the drives themselves.

                                I upgraded to the New Mac Pro and wanted a versatile enclosure for my 2 4TB Blacks. I am running it as 2 seperate drives and have had no issues so far. I love that it is both USB 3.0 and thunderbolt. I have the flexibility of using either connection.

                                I do wish there was an on'off switch. It stays powered up even after ejecting the drives. The only way for it to fully power down is to be either unplug power or the connection to the computer.

                                Used to back up my iMac. Easy setup with two mirrored hard drives. Options available allow total continuous backup or drag and drop selecting. Check the website for additional info. Thunderbolt connectivity makes this product superior to many others.

                                  Purchased OWC external hard drive enclosure and have spent hours trying to format the drives/partition/ getting it to work. The instructions are unclear and I still dont have this thing up and running.

                                  This is a fast, beautifully built drive enclosure. It does as it says, very well.
                                  It could be better in two ways:
                                  1. It's too expensive for a drive housing.
                                  2. There has to be a better, simpler, more elegant way to swap drives out. 12 screws in total? It's build like a tank, but no one is dragging their drives behind a 4x4. What I'm doing is swapping drives out frequently, and screwing, unscrewing, losing and dropping screws . . . the method is arcane.

                                  This is a terrific HD enclosure. Thunderbolt screams in Raid 0 and it was very easy to set up mirrored in Raid 1. It's quiet and runs extremely cool. A much better investment than the other options on the market.

                                  Real world speeds have been around 170 read & write in Raid 1 (mirrored).

                                    Installed the drives, plugged it in and so far it's working perfectly. Very quiet. Have not had the time to install a speed tester yet but it seems pretty quick so far. It's small enough to be able to use from machine to machine and that's the plan. Easy, peasy, lemon Squeezy!
