Rating: 5/5 OWC- WOW what can I say? I am SO glad they exist! August 24, 2014 Been doing business with OWC for many years now- because, as a Mac addict, I need a reliable source I can turn when I need RAM, etc. and OWC has always been there to provide whatever I need to keep my Macs running and prolong their lives. Thank you OWC!

Rating: 5/5 The HDD, new enclosure and cables were perfect June 30, 2014 I bought the DIY Upgrade Bundle to upgrade the internal HDD on my older Mac mini.

The 500GB HGST Travelstar is quiet and it was easy to clone my internal to the new HDD in the OWC Express USB 2.0 Kit. Then I pulled the new drive and swapped it with the internal Mac mini drive that was then installed in the new enclosure.

With the OWC Express USB 2.0 HDD enclosure, it is very easy to install or remove a drive.

Rating: 5/5 Perfect solution February 25, 2012 I'm not by any stretch of the imagination any sort of tech guru, but I know a bit about what goes on under the keyboard/trackpad of my laptop. (I've used OWC to upgrade RAM and order a replacement battery in the past three months - two thumbs up.) I used the online chat feature here on the website to ensure I chose the correct compatible replacement drive for my early 2008 Macbook - from order to receipt in 3 days, couldn't ask for more. Over the course of an evening, I cloned my 160GB hard drive to the new drive (in the enclosure) - swapped it for the old hard drive (original hardware), installed the new expanded drive (and also updated my OS). Not only did I not have a single problem along the way - the assistance documents found on this very website were very informative without being overly simple or geared to the gurus out there, giving me confidence and a feeling of competency/understanding - but the new drive runs quietly and efficiently with triple the storage space. I feel as if my laptop runs better than it has in a while. Having the enclosure for my old hard drive - along with all the tools I needed - was simply the icing on the cake. I'm beyond impressed with the selection and service and felt capable every step of the way.

I would recommend this item to a friend!
