Rating: 5/5 Worked for my needs July 29, 2018 I put the drive from my failing 2010 MacBook Pro in this enclosure so I could copy the contents to another external drive. Installation was a piece of cake. (I agree with another reviewer who noted that the instructions show installing the screws in the reverse positions from what actually works.) The enclosure is well-designed, and fit and finish is excellent. It's plastic, so it maybe wouldn't stand up to a large number of drive changes, so plan accordingly for your needs. It lives up to the quality standards of other products I've purchased from MacSales.

Rating: 5/5 Nice External Enclosure April 1, 2018 This is a nice external enclosure, easy to work with, easy to install a drive.

The case is plastic so if you plan on opening the case a lot to switch drives, this is not the case for you. Get a drive dock instead.

Reviewer: Mamu
Rating: 5/5 A Fine Enclosure March 29, 2018 I had trouble with several hard drive enclosures exhibiting strange problematic behaviors on my Mac Mini so I came to MacSales to get something that was more certain to work. I am not disappointed. This enclosure is working fine and while I haven't bothered to benchmark it at all performance seems plenty fast considering the standard rotational drive I've put inside - certainly USB 3.0 speeds. The only ding I'd give it is that it is not especially sturdy. It's fine, but it would never be mistaken for a rugged product. If you buy one - and id recommend it, just treat it gently.

Rating: 5/5 Perfect March 7, 2018 When my 2011 MacBook Pro died I didn't want to loose it's hard drive (OWC SSD). Just a few minutes with a screwdriver and the drive, with all my data was out of the computer and safely installed in this case. It's now my backup drive. And by the way, backups between two solid state drives are amazingly fast.

Rating: 4/5 Housing is well-made and nice looking. January 26, 2018 Totally my fault for not investigating potential issues first, but I purchased this housing for an upgraded portable Time Machine drive used exclusively with my mid-2015 MacBook Air. (The drive was originally used in a USB2 external enclosure for Time Machine backups with an original white mid-2007 MacBook, so USB2 was all that was required.)

The Good News: This 2.5" external drive housing is high quality, and nice looking, and it works. Time Machine data backups are now faster than the same 1TB 7200rpm HGST Travelstar drive in the old USB2 portable enclosure.

But as I discovered almost immediately, a USB3 signal MAY interfere with WiFi signals (and vice-versa), especially IF the USB3 device is located near the WiFi and Bluetooth antennas.

On the mid-2015 MacBook Air both antennas are apparently located low on the screen in the back near the screen hinge. Because of the short USB3 cable that ships with this enclosure, I originally placed the drive enclosure BEHIND the MacBook Air on the desktop and routed the cable directly BEHIND the computer.

That's a no-no! Because suddenly, my WiFi was no longer reliable. As in, long periods of 0% throughput. Even after rebooting, clearing caches, resetting SMC and PRAM/NVRAM, and updating to the latest version of macOS, High Sierra 10.13.2 (and now 10.13.3)

The enclosed short USB 3 cable comes equipped with two large magnets near the ends to minimize RF interference. Unfortunately, in my setup, there is still enough interference between the USB3 signal and the Wifi signal to bring the WiFi connection to a crawl, or a complete halt. I tried both 2.4Ghz and 5Ghz WiFi connections and re-orienting both the MacBook Air and the router. 5Ghz was a bit better than 2.4Ghz but still not even close to reliable.

What to do? Current Solution: I purchased a longer .9 meter USB3 cable (from the OWC Garage Sale - I will review the cable when I complete this write-up) so it should be among my list of Reviewed Products soon.

With the longer cable, I relocated the USB3 drive enclosure as far away from the MacBook Air as physically possible, on a nightstand about .8 meters away from the computer, stretching the new cable straight out from the MacBook Air USB port to it's full length of about 1 meter, with no cable near the hinge area. Even though this longer cable lacks any magnets to reduce RF, the interference problem has completely disappeared, and both USB3 and Wifi are coexisting peacefully and reliably again.

Rating: 5/5 Simple and quick wawy to harness an old working HD January 26, 2018 After my nephew upgraded his mid-2012, non-retina 13" MBP with a new SSD, I opted to provide him with this simple external case to house his old 5400RPM SATA HD. I has a USB3 connection to maximize his connectivity speed, matching that of the ports on his laptop. Great for use as a generic back-up drive or a Time Machine disk. The installation was dead simple.

Rating: 5/5 Great product and value April 22, 2017 I swapped out the HDD in my daughter's new MBP for an SSD and bought this enclosure to convert it to an external backup drive, and I'm pleased in all respects.

Boot time is respectable for a low end enclosure, and its simple but sturdy construction and compact, easy-to-travel form make the Express an excellent purchase option.

Rating: 5/5 Another OWC winner February 22, 2017 Great value on this elegantly minimalist case. It hugs the 2.5" drive (for me, a 500GB HDD out of my venerable early-2011 15" MacBook Pro) like a glove, and is so simple that there is no power switch and only one port. Build quality is good. I'd gladly pay double for this same case but aluminum. Great regardless!
