Complete DIY bundle kit for adding an extra SSD to the internal SSD bay on 21.5-inch iMac 2011

Add a second SSD to your iMac using the hidden drive bay below the optical drive + keep your DVD drive.

This SSD bundle is not to change your primary HDD but to add another HDD/SSD into your iMac-enabled drive bay. Please watch the video from the Product Videos Tab to understand this upgrade.

The complete solution for your 21.5-inch 2011 iMac

Configuration flexibility is yours when you add a second internal drive using the OWC SSD bay kit. Boost your storage capacity by adding additional storage, and enjoy near-instantaneous boot and app loading times thanks the performance of an OWC 6G SSD.

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.

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.

Includes

  • (1) OWC Mercury Electra 6G SSD
  • (1) 18" SATA III 6Gbps data cable
  • (1) SSD Power Cable for 2011 21" iMac
