Add a Second Drive to your Mac mini
Bigger, Better, Stronger
The Right Tools for the Job
Yes, You Can Do-It-Yourself
- A small number of 2012 units were shipped with the drive mounted in the upper drive bay rather than the more typical lower bay shown in this video. If you have a 2012 or later model, you will want to determine the configuration of your Mac mini's drives prior to ordering. To do this, open Applications/Utilities/Disk Utility.app and click on the grey drive icon at the left-edge of the window. If you see "Lower" after the "Connection ID" at the bottom-left corner of the window, you may proceed using the standard installation instructions. If you see "Upper" then you have a special configuration which will need additional components, and you will need to also refer to the Addendum video.
- Before attempting this installation, OWC recommends watching 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.

I haven't installed the drive yet but I'm sure it will work fine. The only issue I have is once the drive is installed, it appears that in order to merge the two drives is to erase all data on the original drive. Since I'm using this Mac Mini as a media server & have almost 2T of media data on the original drive, I will have to re-install all the media & reconfigure Apple TV & Apple Music again with all my folders etc. Not to mention re-installing my Video & CD programs along with all my other applications on the drive. It appears there is no way around it from everything I have read & researched. Regardless, I'll run out of space very soon & will have no choice but to bite the bullet & do it.
I would recommend this product to a friend!

The price was right. The videos gave me confidence. Still took me 2 weeks to work up courage to do it. I did need some younger eyes to help reconnect two of the cables. Light + magnification would have done the trick. Something like a pencil eraser to press a plug to a socket may help. Was unprepared for the dust bunnies under the cover. Suggest you have some canned air or a gentle vacuum handy when you open your Mac. Also suggest to OWC that the points of the compass be marked on the Mac in the installation video, because the orientation changed a couple of times and I had to really stop and look carefully. Also helpful would be stills of how a plug should be oriented to a socket. Do I have mine reversed left right? Up down? Anyway, it all came out VERY well. Thank you!

I purchased this drive and the data doubler kit to upgrade my 2012 mac mini. am using this drive as an internal backup to the 1 TB SSD that I inserted. put the old spinning HDD in an external case as a way to hold on to current configuration until I am sure the new setup works perfectly. followed the instructions in the online video. compared these instructions to the same ones from ifixit.com. much preferred this style of presentation and especially appreciated the re assemble pathway after the drive installation. I hate it when i get the instruction to just do all the previous steps in the reverse order. having said that, this upgrade did take two hours for my first attempt inside a mini.
