Rating: 5/5 2013 iMac 1GB Mercury Electra 6G SSD Install May 28, 2019 It may of taken me 4 hours to do the install of Mercury Electra 6G SSD on a 2013, 21.5" A1418 iMac with a Fusion drive - but what a difference in performance. *** Adobe Lightroom 6 used to take about a minute to fully load. Now it's less than 10 seconds. Operating time for processing files, such as exporting large TIFF to Photoshop are nearly as fast. *** The provided suction cups and little cutting wheel tool are nice to have. With that said, I was glad to have on hand the iFixIt tool kit, left over from previous SSD install for Mac Mini. It provided multiple guitar picks that were useful when removing the display and a pointed tool that came in handy to secure the adhesive strips. *** Bottom line: I highly recommend this upgrade!

Rating: 5/5 Easy to Do November 10, 2018 I can't say enough how happy I am with this company. This kit made it extremely easy to upgrade the hard drive in this iMac.

This was an older iMac that I stopped using when I got a 27". I gave this to my kids. But the built in mechanical hard drive was terrible and my kids couldn't use this very well d/t how slow everything responded.

After doing this upgrade myself, this iMac flies Late 2012 iMac 21.5" 2.7GHz i5 8GB Memory NVIDIA GeForce GT 640M 512MB

This was extremely easy to install. I could have probably done it in 20 minutes but removing the original tape from the iMac took me about 25 itself. The video from the OWC website guided me along accurately.

Highly recommended!

Rating: 5/5 Easy installation and incredibly performance boost September 30, 2018 A local shop wanted $700 to swap the HDD for a new SSD. I am very glad to have found OWC and their kit and instructions to do the job myself. Overall the job took about an hour, the kit had everything I needed to do the job correctly, and the result is great. My 2013 iMac was becoming unusably slow - Spotify took 10 minutes to fully open and launching Word almost always crashed the computer. After swapping to the new SSD, the performance for my work flow is more or less equal to my 2018 MacBook Pro. The kit was a huge money saver and should make my iMac a sold computer for several more years.

Reviewer: Jafa Experience Level: Power User Owned Product: less than a month

Rating: 5/5 Great SSD Drive and Kit But Do Your Homework Before Installing May 18, 2018 I purchased the Mercury Electra 6G 500GB SSD kit to replace my late 2012 iMac's failing 1TB internal SATA hard drive. The SSD itself is phenomenal performance-wise and lightning-fast compared to the stock drive. I'm extremely happy with the purchase of the SSD. The installation kit was also top-notch, especially the plastic micro-sized pizza cutter which greatly assists in cutting the adhesive strips that attach the iMac's display to the frame. The included suction cups and screwdriver were also very helpful. I ended up having to order additional adhesive strips (which are unlabeled and only come in one length as opposed to the labeled custom-length strips included with the kit). This was due to me not reviewing multiple installation instruction videos as I should have before starting the installation. The OWC video is good, but there are multiple other videos out there which should also be viewed prior to starting the project. I learned this the hard way when I re-sealed my iMac display after installing the SSD drive. I didn't test the iMac by starting it up prior to sealing the display to the frame. The OWC install video doesn't hammer that step home as much as it should (other videos are very clear on that step), and, had I tested it before sealing it up, I would have noticed that one of the display cables had come loose as I was sealing the display to the frame. I sealed it, started it up, and...no video. The end result was that I had to unseal it again, reconnect the loose cable, and leave the display taped onto the frame with painter's tape until the new adhesive strips arrived and I could seal it back up properly. This was my own fault in the end for not doing enough research and only watching the one OWC installation video before jumping into the installation. My advice: the upgrade is definitely worth it, but do your homework before attempting the installation yourself!

Rating: 5/5 OMG, a must upgrade to iMac! May 1, 2018 I was prepared to just dispose of my iMac and buy another one but really didn't have the money to buy a new one. An Apple tech told me my HD was failing and causing my problems so I found mac sales.com and ordered a new HD for my iMac. The video instructions were excellent and it took less than 30 min. I received the part on a Friday and did it over the weekend so I did have one hang up, the instructions I found didn't mention the new drive had to be partitioned. I asked a friend and he told me this is why the iMac wouldn't recognize the new drive, easy process to partition but I wish the instructions were clear this had to be done. After that, it was fine. It's amazing now, better than it ever was new. Programs load up instantly. I'm simply amazed.

Rating: 4/5 no more beach ball April 25, 2018 The hard drive itself works great. I followed the instructions from the video and it was very straight forward. Having a time machine backup made recover of all the data simple. My only gripe, which is why I knocked off one star, was that the kit was missing one adhesive strip for remounting the screen. I had to make due with no adhesive on the left side. I do not live close enough to anything to get the particular strip in a timely matter so I had to mount the screen anyway. I think it will hold. I would say it took less than an hour but the reinstall of data was much longer.

Rating: 5/5 Scary at first, but excellent kit and instructions January 2, 2018 I had been considering replacing or upgrading my iMac 4k because rebooting and app loading was taking so long, even with a stock Fusion 1T drive. I couldn't find any comparison reports between an SSD and a Fusion drive, but it seemed like an SSD should make a big difference, and it did. I watched the installation video, and felt apprehensive about tearing my fairly new iMac apart. But I've got to say that the installation kit was very well done. It includes every tool and part needed. I especially like that the adhesive strips are color coded, and have tabs on both sides to simplify pulling the adhesive covering off before and after sticking them into place. Overall it didn't take nearly as long as I expected, maybe about an hour.

Swapping in the subject SSD kit made a huge improvement, sorry no benchmarks but subjectively. Swapping the system drive was more an arts and crafts project than the usual computer repair. The you tube video was an important part of the process. Extra hands and fingers are also useful. I found my wife's assistance invaluable in placing the adhesive strips to resecure the screen and in holding parts in place. This change made the computer behave much more like I had expected when purchased.

Rating: 5/5 Easy Upgrade. February 15, 2017 I was scared initially to open up my new 4K iMac. But once I started I was surprised how easy it was and the entire process of swapping the hard drive to SSD was simple and was done in 20 mins. SSD makes a ton of difference to the system performance and would advise anyone to swap it if they bought a mechanical hdd equipped Mac.

Rating: 5/5 iMac like a rocket now February 1, 2017 I wanted to take the time to come and write a review of my recent purchase and self installation of a SSD drive in my 21.5" late 2013 iMac. From the product selection process on OWC's website helping me locate my exact SSD to the shipping video replacement guide and former HD (1TB) content migration, all went fantastic. My wife was always complaining about the spinning beachball she would endure. This has been completely eliminated. The machine has become a pleasure to work on now. If you value your time, I highly recommend an upgrade from ordinary HD's to SSD. Thank you Other World Computing!

Rating: 5/5 Excellent service, top notch instructions! December 4, 2016 My iMac became painfully slow boot up and getting the spinning ball of death all the time watched the video on this installation it was very intuitive and took the plunge my iMac is like new and very snappy - tripled my read/write speeds, don't be afraid of this upgrade very easy took 20 minutes and most of that was peeling off the old adhesive. Oh and don't panic if you misplace a strip or two of new adhesive the kit provides extras!

Rating: 4/5 Worked like a charm September 6, 2016 Successfully upgraded HDD to an SSD in my parents' iMac, radically improving its speed/response. OWC made it do-able, if not exactly easy. Watched the videos many,many times, and took great care at all times and it all worked out. It is not for the faint of heart, but it was less of a big deal than I expected.

They will get another five years out of the iMac, I bet.

Rating: 5/5 Great SSD July 8, 2016 My factory installed hard drive began to fail on my iMac after only two years. After viewing the OWC video on replacing it, I decided to try to replace it. Everything worked as advertised and now I have an iMac that is working better than ever.

Having a 1Tb internal hard drive fail has caused me to keep all important files on an external drive and backup everything.
