Experience the extreme performance of an OWC SSD upgrade with this easy DIY SSD and hard drive replacement kit. Add an SSD to your hard drive equipped iMac to experience faster booting, near instant application launches and data transfer speeds up over 500 MB/s.
Fast and reliable solid-state storage
With sustained data speeds of over 500 MB/s, up to 100X greater data protection than enterprise class Hard Disk Drives, and RAISE technology for RAID like data protection and reliability, the OWC Mercury 6G SSD line delivers unbeatable performance, that's backed by an incredible OWC SSD Limited Warranty.
Upgrade Your iMac with Confidence.
OWC's in-line solution is the only hardware digital thermal sensor on the market allowing a third-party SATA drive to be installed in your iMac. A convenient, plug-and-play cable, the In-line Digital Thermal Sensor eliminates fan noise and maintains proper system fan control through the iMac's System Management Controller. This innovative device is designed specifically for the iMac, requires no software hacks and ensures compatibility with Apple's built-in diagnostic processes.
Maintains highest performance while offering ultimate convenience
The NewerTech AdaptaDrive has been benchmark test proven to deliver the same data transfer rates as is experienced when a drive is connected directly to the SATA data bus. The AdaptaDrive doesn't create a bottleneck or any performance throttling...it delivers pure data pass-through performance and drive use convenience from any 2.5" SATA 1.5Gb/s, 3Gb/s, or 6Gb/s hard drive or SSD.


Please note, that before attempting to perform this installation, it is recommended you watch the associated instructional video in its entirety to determine your ability to perform this complex procedure. OWC assumes no responsibility for damage that may occur during the install.

Release Candidate (RC) firmware set

There are two kinds of firmware for SSDs Mass Production (MP) and Release Candidate (RC). Prior to an MP firmware release, there are beta firmware releases and an RC firmware release. Often, the RC is the same as the MP release, however there can be small changes and bug fixes made between the two. OWC has evaluated the RC for the 6Gb/s SandForce 2281 Processor and found it to be stable with no issues reported during our testing. However, as with any evolutionary product, issues may surface as different usages and configurations are employed and it is important to understand that there will be further updates and revisions.

Since no firmware update is currently offered for the OWC Mercury EXTREME Pro 6G SSD, no update page exists. To see the typical steps involved with a self performed field firmware update, please visit our 3Gb/s product update page at: http://eshop.macsales.com/Customized_Pages/Framework.cfm?page=sf_firmware.html

It is important to note that the current firmware update tool requires the use of Windows XP/Vista/7. OWC is currently working on a Mac OS based update tool, but we do not have an exact availability date.

  1. 1GB = 1,000,000,000 bytes. Total accessible capacity varies depending upon operating environment (typically 5-10% less). The actual total capacity will depend on your own defined file settings/preferences. 
  2. In terms of standard gigabytes, 1GiB ≈ 1.074GB and refers to the actual formatted capacity of shown under Mac OS 10.5 or earlier and Microsoft Windows OS.
  3. Specific application environments such as temperature and duty cycle will affect the overall reliability.
  4. Specifications provided by SandForce.
  5. Temperature reporting is currently an unsupported feature because due to the operating characteristics of SSDs, it is highly unlikely one would ever exceed an OWC Mercury SSD's stated operating temperature ceiling of 158F/70C. However, we are looking into supporting this feature in the future via a firmware update. Firmware updates can be found here: http://eshop.macsales.com/tech_center/OWC/SSD.

Rating: 4/5 Great cost effective way to upgrade iMac April 29, 2018 Great way to save ~$700 vs purchasing with this option. The only issue was that the adhesive strips that come with the kit cover up the microphone on the mid 2017 27" imac, resulting in a muffled and unusable microphone. The microphone is now located at the bottom, about 3 inches to the right of center (look for 3 small holes and a small vertical ribbon cable). After OWC sent out another set of adhesive strips, the second time around I cut out this section and now the microphone is as good as new.

Rating: 5/5 You can do it! November 21, 2017 I had second thoughts about attempting this HD replacement but ordered this kit anyway. Everything you need to accomplish this task is included. The install video is very comprehensive and along with other videos reviewed on YouTube made the difference. Even installing the adhesive strips to secure the screen went smoothly.

I would recommend temporarily reattaching the display without adhesive to test this installation before installing the strips.

The install video states the time to complete at 1 hour. As an occasional up-grader I worked slowly and it took about 3 hours.

Rating: 5/5 Believe the hype! November 15, 2017 Upgrading my 2012 iMac with an SSD was an amazing investment. It is twice as fast as it ever was. From start up to launching apps, everything is nearly instant. This computer has never seen speeds like it is now. The kit had everything needed to swap out the drive. My tech wizard had no problems making the swap as I felt more comfy letting a pro rip my baby open. Two thumbs way up!

Rating: 5/5 Awesome upgrade December 10, 2016 My 2012 iMac really flies after this upgrade! All of the right tools were provided. The video was nice, although it shows installing a spinner. Installation is not difficult, it is just tedious.

I had to command-r on boot to get to the restore menu. I installed using a time machine backup.

Highly recommended. It is hard to put in words the difference between this SSD and an the old drive. Everything is instant now! Great kit!
