Rating: 5/5 More than just a solid expansion choice October 29, 2020 When considering this drive the obvious question to ask is, "why not grab one of those cheap-o drive chassis I see around the internet instead?" I use this OWC external hard drive enclosure as well as a cheap one, so I'll tell you about the features of the OWC enclosure that make it right for some tasks. As with most things, you get what you pay for. This expansion drive is big with a generous area around the drive to house the controller board. What's more, instead of the PCB being a mass of solder or hot glue, parts that aught to be detachable are. For instance, if you don't like that blue LED, you can unplug it from the board without permanently damaging your purchase. Instead of the HD just sitting in the chassis, screws that pass through rubber gaskets hold it in place. These significantly decrease the vibration felt from the drive spinning. I use this to hold a high RPM HD on my desk that stores content libraries for virtual instruments with a music keyboard plugged into the extra port. I can't feel the drive spinning while I work and when I'm done, turning off the power on the drive handily turns off my keyboard too. I use a cheap enclosure to hold a low RPM drive attached to my router to do wireless Time Machine backups. Since it's behind the couch, the noise and vibration don't matter.

Rating: 5/5 Superb Enclosure on every level plus USB3 port as lagniappe October 12, 2019 Love this enclosure; have purchased it a number of times for repurposing drives from upgrades over the years.

Very easy (and secure) installation of drive; really not liking the trend towards "screw-less/tool-less" plastic enclosures I'm seeing on Amazon, which feel cheap & flimsy. The Mercury Elite feels like a tank and would be my "best weapon on desk" in the event of a zombie attack.

Rock solid performance as well; never a hiccup in regular use from any of the ones I'm using or the friends/family/clients whom have received (again; it's my go-to case for repurposed HDDs/SSDs when upgrading internal storage).

I'm also a very big fan of the "single-port USB3 hub" design as lagniappe. It's been great and been a "oh, wait, I do have an open port" moment many times.

Highest possible recommendation.

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.

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!

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

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 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 OWC, 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.
