Rating: 5/5 120GB Mercury Electra 6G SSD 2.5" Serial-ATA February 12, 2016 The SSD breathed new life to my sluggish old MacBookPro 3,1. It made a radical difference in loading programs, from 45 seconds to one minute to 15 seconds. It's too small, of course, but it was what I could afford at the time. It is now in my MacBook 1, keeping it lively.

Rating: 5/5 iMac Mid-2014 February 11, 2016 Contacted Apple asking if there was anyway to upgrade my HDD to an SSD, and they told me it wasn't possible, and I would just have to stick to my HDD. I didn't like this answer, so I bought this external drive in hopes to velcroe it to the back of my computer and reap the rewards.

This is exactly what I did.

So far (~1 month after purchase) this SSD has done everything I need it to do. First thing I did was velcroe it to the back making for easy transport, and keep it out of my eye sight. It's set to boot El Capitan, has programs like Xcode, Sketch, etc. and can run circles around my HDD. This is probably the best thing I've treated myself to in a while, and I highly recommend it! The best part is, I can keep everything I need in an instant on my SSD, and things like games, music, etc. can go on my HDD to save space.

Just make you remember to buy the enclosure at checkout if you don't already have a SATA to USB adaptor, I forgot to do so and ended up paying for shipping twice.

To give some comparison as to the speed of this SSD: I have a 5400 RPM HDD (nothing crazy) and before, opening apps would take ~6-15 seconds averaging at 7 seconds, since I made the switch, I get launch times of ~0-4 seconds averaging at about 0.5 seconds for small applications.

Boot times? Before: 1 minute 13 seconds After: 33 seconds

Response from MacSales.com, Marketing February 12, 2016 There is an alternate solution here where you CAN install an OWC SSD internally and repurpose the internal HDD as external storage: http://eshop.macsales.com/item/OWC/K21IM12HE120/ You can view all the solutions for your 2012 or later 21-inch iMac here: http://eshop.macsales.com/Search/?Ntk=Primary&Ns=P_Price%7c1&N=0&Ntt=*OWCK21IM12HE *

Reviewer: Anonymous Location: Boston Age: Over 65 Experience Level: IT Professional Owned Product: 1-3 months

Rating: 5/5 Very Fast February 5, 2016 The only problem I had was that the OWC SSD would not recognize my old stock Apple Hitachi Original ATA drive; it kept reporting the, now, externally USB-connected unit as a "Master Boot" formatted volume, instead of GUID.

Ultimately, I had to erase, re-format and partition the Apple-supplied one in order to get it properly recognized: luckily, I had a recent Time Machine backup of that one, and restored it as GUID, which it already was, but not correctly identified as such. That was inconvenient, to say the least.

The OWC SSD is very fast, stable and responsive. I use it for Production of Media, and store the results elsewhere, as I bought the small 60 gig one.

It could be that 'El Capitan' installed on the new one had some kind of issue with 'Lion' on the old drive. I worked it out, eventually. It's all OK.

Rating: 5/5 "Old" iMac boots in 20 seconds January 7, 2016 I installed the 240 Gb SSD in my 2011 iMac (model 12,2). So the SSD goes behind the superdrive. I never thought I’d dare to do this, but with the help of the OWC instruction video (and the DIY kit) it went like a breeze. (But watch that vertical sync cable in the beginning - that's a bit tricky.) I then made a fusion drive, installed El Capitan and then restored my Time Machine to the new drive. And lo and behold: My “old” iMac boots in about 20 seconds (this used to take 4 minutes or so). So would I recommend this? What do you think.....?

Rating: 5/5 Solid State December 5, 2015 Changed out our old hard drive (5400rpm) for solid state drive. The swap was so simple. The drive was installed in no time and files transferred onto the new one in a few hours by usb. Highly recommend this for anyone who wants a faster computer. Our MacBook Pro must be at least 10x faster than before.

Rating: 5/5 Excellent December 1, 2015 I bought my 1.0TB Mercury Electra 6G 2.5-inch 7mm SATA 6.0Gb/s Solid-State Drive via internet, from Italy. I received it a in very short time I installed it on my Mac Book Pro ed the result was extraordinary: the startup now requires a few seconds whereas previously it was necessary to wait for long minutes. I am very happy of this spending.

Rating: 5/5 Amazing November 30, 2015 If I don't see it, don't believe. I upgraded my 2011 macbook pro with a SSD and is faster than brand new. Only one complaint not to have done before.

Rating: 5/5 Best bang for the buck November 22, 2015 I replaced the conventional hard drive in my wife's MacBook Pro with this SSD drive and breathed new life into her aging machine. Installation was easy. Results were comparable to those in my two iMacs which I had also upgraded months ago with OWC SSD kits. If your Mac is still saddled with an older mechanical hard drive, you owe it to yourself to step up to an SSD. The difference in performance is like night and day.

Rating: 5/5 Love this SSD! November 20, 2015 I might be a bit crazy ... but ... I first up installed this to be my 480 Gig boot drive replacing the undersized Apple supplied unit. (cost was a factor as to what I could afford) At the same time I replaced the original HDD with a 3 TB Toshiba HDD. Wow ... now I felt I had a bit of space and was no longer juggling or being concerned as to where software was going to be. Simply put, I configured the Users/home directory on the 3TB drive and the OS and programs on the SSD. Just recently I removed the optical drive and fitted a 960 Gig SSD as well. This way I was able to do a clean install of El Capitan on the 960 gig SSD and maintain Yosemite on the 480 gig SSD. Now I have lightning fast boot into either OS and just love it. Upgrading is now a much safer and controlled transition for me.

Rating: 5/5 Screamer November 20, 2015 This drive is killer!

If you can get 6Gbps throughput, the series is amazing.

My iMac 27 2011 boots in a few dozen seconds.

It doesn't require TRIM but you can turn it on via the terminal. The drive won't care.

Highly recommended!

Rating: 5/5 Can;t belive I did not buy this sooner November 16, 2015 Best investment ever. I should've bought this long ago. My MAC Pro boots in less that 10 secs. Together with the 32GB Ram I purchased from OWC, my MAC Pro is a powerhouse. The cost is a little high but definitely worth the money. I hope to buy one more 480GB SSD Drive in the future is they price drops.

Rating: 5/5 Fast as expected, BUT some installation issues. Still give it five stars. November 7, 2015 Executive Summary:

Performance improvement as expected, but some 10.5 & 10.6 CD media might not recognize the SSD.

Details:

This was for an older Macbook (7,1) which had come installed with 10.6.— a likely candidate for memory and SSD upgrades.

I’ve swapped several new hard drives and an SSD before, so my plan was to - install the new SSD - boot up a Snow Leopard Installer from a CDROM - format the new SSD - install Snow Leopard - update using the Internet to Yosemite (or El Capitan)

However, the 10.6 CD Installer would not recognize the SSD, nor would the Disk Utility. Strangely enough, the System Profiler did.

I booted up on the old disk, using an enclosure and even when I formatted the SSD & tried again, the 10.6 CD Installer could not see the SSD.

So, i again boot up the original hard drive (with 10.6 on it), and used Disk Utility to clone its own image to the SSD.

I rebooted and then every thing was ducky.

A web based install of El Capitan was not an option as it only works with machines that originally had Internet Recovery in its version of OS X (not an option for this Macbook).

I got the info on 10.5 & 10.6 Installer failures from OCW Tech Support — seems like some CD versions do not recognize the SSD.

So, if you want to update an older Mac to an SSD, you might try using something like Disk Utility or Carbon Copy Cloner to load the SSD.

I’ll pass on this info to OWC Sales so they can put this in their technical info for their SSDs.

Bottom line:

Once installed, the system is really fast & responsive. The SSD and extra memory should allow El Capitan to run with reasonable response times.
