Rating: 5/5 Just what I needed January 18, 2016 The time had come to enlarge my hard drive, and when an irritating pop up had infected my computer asking me to "clean up my mac" (which I tried to get rid of it without any success), I took the plunge! So I ordered a new hard drive, and followed the excellent videos of changing out my hard drive with one twice the size. I did call customer service and received an immediate answer to my question of how to reformat the new drive, and after hooking up with apple, the necessary files were downloaded directly to my hard drive, and after a few hours, I was back in business with Yosemite operating system. A couple of days later I upgraded to El Captian, and now I am all up-to-date and very happy with my MacBook Pro. I am sorry that I hadn't done it sooner. I appreciate so much the easy to follow video instructions and excellent Customer Service to make sure I was on the right path.

I would recommend this item to a friend!

Rating: 5/5 Delighted September 9, 2014 The product installation video gave me all of the information that I needed to install this new drive, thus tripling the hard-drive capacity of my machine. Installation required maybe 10 minutes. Since installation six months ago, the drive has operated flawlessly.

Rating: 5/5 Quick shipment, great tech support from OWC August 24, 2014 This was my first purchase from OWC. Being a late-comer to the Mac world and having had very few Apple hardware problems in the past, I asked a long-time Mac devotee about how to replace the hard drive in my early-2008 MacBook Pro. The folks at my local Apple store had diagnosed the problem but said they could not work on it because the laptop was more than 5 years old. They referred me to a third-party vendor, who wanted $490 to make the swap and to move my operating system and data to the new hard drive. My friend told me about OWC and their free video tutorials for do-it-yourself repairs. After selecting the drive I wanted from the OWC website I called OWC and learned I could get a tool kit for an additional $10 that would make the job easy. Four days later I was up and running with my larger, faster new hard drive that worked on the first try, thanks to the great step-by-step video. Thanks!

Rating: 4/5 Drive works great, good enclosure & tool kit July 4, 2014 750GB drive is working as I would expect. The enclosure that is supplied is really only meant to be used as a temporary enclosure to transfer files to a new hard drive. I would not recommend it as a permanent enclosure as it's a little flimsy. The tool set is great and very useful for any computer repair type work.

Rating: 5/5 EXACTLY what I was looking for...and it delivered! March 8, 2011 I had been thinking about upgrading my late 2006 MacBook Pro for some time. The 120GB drive it came with was running low on real-estate. I am a music-junkie so my iTunes was consuming most of my HD. I knew if I upgraded I wanted the most BANG for my BUCK.

OWC made selecting the right drive for my needs via the MyOWC tab on their webpage a painless and stress-free experience. I am a music professional so I have seen OWC products floating hear and there but never owned any. People turned me onto their website and after seeing their products in-action I knew this was where I wanted to concentrate my upgrading process.

I was impressed from start to finish with the Scorpio Black drive. I was very pleased to see that I was going from a 120GB 5400rpm to 750GB 7200rpm for less than $200! THIS IS AN AWESOME VALUE! Out of the box the drive felt solid; a bit "heavy" but I was expecting that with the level of capacity. I took what OWC was saying about the Scorpio Black and was burning up the internet viewing both professional and novice reviews. Most of what I found was singing praises about the 500GB version of this drive. GREAT! If people were raving about the 500GB drive I felt confident I would be stoked to get my hands on the 750GB version. I have no regrets. I have had the drive installed for over 3 weeks and its has performed flawlessly. It formatted well and installed Snow Leopard without a hitch.

TIP: I thought there was something wrong after installing Snow Leopard when it did not automatically boot from the Scorpio Black in the enclosure. I later discovered by holding down the option key at startup you can select the new drive in the enclosure. That was my only hiccup.

I followed the OWC website video and instructions about swapping out a hard drive and the "surgery" went well. It started right up after swapping it out. Even though there are obvious and noticeable performance increases which come from upgrading from my stock HD, I am impressed with the Scorpio Black. I highly recommend this item for your consideration!

Also, I did not have the "tools" to pull of the "surgery". Having what I was looking for in a HD as well as all the accessories to get the job done from start to finish was a great help especially at such a price! The kit was very helpful in the upgrading process. Having the enclosure to put the Scorpio Black drive was great!

I would recommend this item to a friend!
