SSD, thermal sensor and installation tools to swap the main HDD for SSD on 21.5 and 27-inch iMacs 2011

The complete solution for your 2011 iMac
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 lightning-fast data transfer speeds.

Starts fast, stays fast.
Even though many SSDs use low cost, less robust components in their design, they can still offer enticing short-term bust speeds which are perfectly suitable for light-duty uses. However, those drives are not designed to deliver consistent, sustained speeds over their capacity rating, which results in a dramatic slowdown to even hard drive speeds under demanding use.

The fifth generation of Mercury Electra 6G SSD was built to start fast and stay fast at over 500MB/s sustained. Its development began with using the best flash storage components and technology available. Next, after being nearly completely filled to capacity with data, it had to deliver the same high speed as if it were empty. This drive doesn’t flinch at any time or capacity level and drop read/write speeds like other drives do…it easily handles the most extreme, mission-critical uses you can throw at it.

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 the 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 installation.

OWC DIY Bundle with Mercury Electra 6G SSD to swap main HDD for SSD on all 2011 iMac

Bought this for my ageing Mid 2011 IMac and absolutely delighted. The kit contained everything required to replace my old HD and the online instructions made it a simple fix. The iMac now runs good as new.
