OWC 2009-2011 iMac Data Doubler Kit, 1.0TB 2.5" Seagate BarraCuda 7200RPM Hard Drive and OWC 14 Piece Toolkit

OWC Internal Hard Drive DIY Kit
Everything you need in one package to replace your 2009-2011 iMac's internal optical drive with 1.0TB of fast (7200 RPM) storage.
Configuration flexibility is yours when you replace your iMac's internal SuperDrive with the OWC Data Doubler. Bundle includes bracket, screws, OWC Microfiber cloth, suctions cups, tools and a Quick Start Guide for a complete all in one solution.

Then, just install the entire assembly into an iMac's 5.25" optical drive bay. OWC Data Doubler makes it easy to custom design how you want your internal storage to perform. Installed drives are recognized like any other high speed SATA storage device and can be setup and partitioned using the Apple Disk Utility Program.
Just a few of the configuration options you can enjoy with Data Doubler:
  • Combining a new drive with the existing internal drive for one larger volume (SPAN).
  • Combining a new matching drive with existing internal for high-performance RAID-0 Stripe volume.
  • Configuring a new drive as a Time Machine backup drive.
  • Formatting one drive for the Mac OS and the other dedicated for Windows.

You don't have to give up your optical drive completely if you don't want to. You can reuse the original SuperDrive with the OWC Value Line Slim optical drive enclosure for Apple SuperDrive.

*Professional installation of Data Doubler into an iMac is highly recommended due to degree of installation difficulty

Rating: 5/5 Take Advantage of Wasted Optical Space March 5, 2018 I mean like who really needs a built in optical drive? Especially after it fails big time. Buy a $20 external optical, put it in the drawer because you hardly ever use it...and take advantage of the space in your iMac for some onboard, cable free, space!! The other good thing is that you'll have an opportunity to retrieve all of those SD Cards that you shot into the wrong slot :-)

I would recommend this item to a friend!
