Rating: 5/5 Owc is always the best. June 1, 2021 Took me 5 minutes to put together and with an ssd fit is tight and it is fast, think we cloned a hard drive with 400gb in 25-40 min. Real6Gbps speed (with 6Gbps SSD). Amazing value, comes with a real USB SS cord too...

Rating: 2/5 Drive/OS mismatch May 31, 2021 Purchased product for my wife's older desktop Mac. Turns out that it will not work because she cannot upgrade to a sufficiently recent operating system which is required by the product. Returns are a hassle so I an keeping it in case I need one for my desktop Mac someday. Disappointing that it wasn't clear that it would not work with OS 10.10.

Rating: 4/5 Inexpensive enclosure from a name I trust. September 7, 2020 I've used many different enclosures like this from various brands, and often they are of questionable quality and have high failure and DOA rates. This one has given me no trouble in the year I've owned it. Simple, inexpensive, and reliable. It is still made of plastic so it would be better if metal, but there are other products for that.

Rating: 4/5 Affordable quality June 24, 2019 The external hard drive was at a good price and I decided to buy it to have somewhere to store my school and work files. It`s basic, but my only complaint is the case it comes in feels a little flimsy. But it is very light and easy to carry with me on the go. Overall I`m very happy, and I don`t care about writing speeds, as long as I have lots of memory and writes at a decent speed. It also came with a small carry case.

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.
