Fast and reliable solid-state storage
Delivering the latest in flash NAND and controller technology, utilizing SLC and 3D NAND for long-lasting, power-efficient performance, the OWC Mercury 6G SSD line offers a powerful combination of performance and reliability for demanding everyday computer users.
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.

  2. 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.

Reviewer: jmcc101 Location: Connecticut
Rating: 5/5 Works as expected February 17, 2017 Significant performance improvement over the standard Fusion Drive that came with the 2014 Retina iMac. Installation was not as complicated as I thought it would be after watching a few videos of the process. It took about an hour to complete.

If you have the tools, the DIY bundle from MacSales, and are not too intimidated, its worth it.

I would recommend this item to a friend! This review is from DIY Kit for 2012 or later 27" iMac's factory HDD: 1.0TB OWC Mercury Electra 6G SSD.. Customer Videos:

Reviewer: mkilar Location: Long Island, NY Experience Level: IT Professional Owned Product: less than a month
Rating: 5/5 Late 2013 iMac 27 SSD Upgrade February 7, 2017 I chose to upgrade a 3TB HDD to a 2TB SSD from MacSales in order to get a speed boost. While not an upgrade for beginners, the process went smoothly and without any problems. The "new" iMac is now significantly faster in booting, image activation, and I/O in general. Very pleased with the results.
