Rating: 5/5 Great Enclosure from OWC!! August 1, 2018 My daughters iMac computer died and she was set to recycle it and I told her I could get the hard drive out and get all her data back -- she couldn't believe it. I knew exactly where to go - OWC. I have been shopping there for many years and it is my goto place for Mac accesories. The Mercury Elite Pro enclosure kit was delivered in no time, I installed the drive without having to read any instructions (it was just too simple). Plugged the drive into her Mac laptop and there was all her data., She was shocked about how easy it was. Another great product from OWC. Always there for me with the right product I need and hope they will always be there.

Rating: 5/5 My Second One! July 8, 2018 I first purchased a 2.0TB OWC Mercury Elite Pro about a year ago for Time Machine. I needed another external drive for cloning, so my first choice was another Mercury Elite Pro. OWC's online ordering process is easy to use. Shipping costs are reasonable. The product arrived much sooner than expected. The packaging was well done and secure. Everything worked perfectly right out of the box. I created two partitions. One for manual misc backups, the other for CC Cloner. I have run two clones so far without any issues.

Rating: 5/5 Great product; great price June 8, 2018 The setup for this drive was very easy. In part, that is because I am using on a Mac; but the OWC setup software made it easier still.

This is the quietest drive I have ever owned. The only way to tell when it is in use is to see the blue flashing light.

Rating: 5/5 Excellent value! May 9, 2018 I've been on the lookout for a new external hard drive, for my exploding media collection, and I came across this enclosure for a hard drive. It didn't have a hard drive included, but was a great value so I took a chance on this and a hard drive for it. It is wonderful and quiet (great for being located near a bedroom), and I've had zero issues with it to this point!

They are very knowledgeable about all their products and how that may help you solve your situation. I have purchased all my upgrades for my MAC Pro and will continue as long as we can keep it running.

This backup installed and works flawlessly as did the other one I bought in the past (filled it up).

I will be back.

Rating: 5/5 Excellent Drive Enclosure March 2, 2018 I bought this enclosure to put my old HD Hard Drive into when I replaced it with the 1 TB SSD drive I bought from MacSales.com. This works great. It gives you very easy way to install your hard drive or an SSD extra drive and connect it via USB 3.0. Inside the bay it has a SATA connector and my old drive slid right in it. It works very well just as advertised.

Rating: 5/5 Good solid product January 10, 2018 Like everything else I’ve bought from OWC, this is a good, solid product. It’s not my first external from OWC. This drive is replacing that drive, purchased in 2012. I think that’s a good run. And I know that if there is a problem, their excellent customer support will take care of it.

Rating: 5/5 Excellent USB 3 Enclosure December 22, 2017 I bought this to replace a extremely cheap plastic enclosure that I had endured for far too long as my Time Machine backup drive. This is very nice quality. Solid build. I had my own drive, so just got the empty version and couldn't be happier. It looks very nice and behaves how I expect it to. Would definitely recommend.

Rating: 5/5 OWC does it again (this is a good thing) December 11, 2017 I've used OWC many times over the years for memory and drives. The 2 OWC USB Mercury Elite Pro enclosures I purchased are just what I needed: easy to install my drives and very, very quiet. Once the issue below was solved they have been running flawlessly and the USB 3 connection is very responsive even when pulling large files into Illustrator or Photoshop. About Tech support: I did have a problem after I connected the drives up: when the computer went to sleep both drives (daisy chained) would start to spin down, then start right back up ever 30 to 60 seconds. I called text support with this very unusual problem and we worked through it for 58 minutes as we had to try several solutions, then reboot and put the computer to sleep, to see if the problem persisted. The problem was with the iMac, not the drives. By shutting the computer down, unplugging it, holding the start button down for 11 seconds or more, then rebooting the computer (after plugging it back in, of course) the problem was solved. I appreciate the time and patience it took to work through this problem.

Response from MacSales.com, TEA October 9, 2017 Unfortunately, the limitation for S.M.A.R.T. support is due to the USB interface, and not the enclosure. We are working on software that would allow you to support S.M.A.R.T. for external drives, SMART Alec.

Rating: 5/5 Great products from a great company April 17, 2017 I have purchased products -- mostly hard drives and computer memory -- from this company since the 1990s and have never been disappointed. I have always gotten a minimum of five years' service out of all the hard drives I've ever purchased (I make it a point to retire hard drives after five years). I still have all the old drives around and, should I need them, I find that they will still spin up properly. The only real problem I've ever had is with a stick of RAM that went bad. It was still under warranty and was quickly replaced with no undue questions. In all, it's been at least 20 years (or so) of stellar experience with this company.

Rating: 5/5 Excellent External Drive/Good Value April 2, 2017 This is the fourth Mercury Elite Pro External HDD that I've purchased over the last several years. I've had this particular one for only a couple of weeks, but I have been using three others for up to several years now with no complaints. They have all been highly reliable for backing up important files on our Mac-based system, essentially enterprise levels of reliability. They are easy to setup and integrate into any home or office PC and/or network structure. I have only used single, stand-alone drives rather than available RAID-compliant multi-drive enclosures, but would expect the same results in that application as well. I would highly recommend the OWC Mercury Elite Pro.

March 17, 2017 As I have come to expect from OWC products, this ElitePro hard drive enclosure is perfect - well made, easy to open and to install the drive, and after a couple weeks in service seems to work perfectly with no glitches. Spent 10 minutes putting it into service as my Time Machine back up drive, and then proceeded to forget it was even there - just what you want and expect from high quality gear. Thanks OWC!!

Rating: 5/5 Great 3.5" Drive Enclosure January 16, 2017 The Mercury Elite Pro USB 3 With USB+1 HDD Enclosure Kit is a heavy duty all aluminum drive enclosure for your 3.5" SATA hard drive. It is built to last, looks good, and worked with my Mac with no issues at all. I use it for automated Time Machine backups, and it works flawlessly, spinning up whenever needed. It has a heavy duty 24" USB 3.0 cable, and its own a DC power supply. A nice toggle switch on the back allows it to be manually shut off if needed. Also on the back is the USB+1, a USB 3.0 port you can use to plug in any other USB device you might need to. The drive therefore gives you back the USB port it takes up!
