![]() Until recently, this drive was not supported under OSX. About a year ago, Western Digital released a 2.5" hybrid drive with 120GB NAND cache + 1TB platter drive in a single 2.5" laptop drive mechanism, under the name Western Digital Black2. ![]() ![]() But you'll only know whether it works once you've reassembled it. From the looks of the socket, the module uses an mSATA connector. If you're inclined to try an experiment, iFixit has a guide for removing the SSD in a 2013 27" iMac I'm guessing that the logic board of the 2014 non-Retina generation is similar. I haven't read any reports of someone trying to install such a PCIe module and failing, so who knows? Maybe Apple uses a different implementation on the iMacs. If you stick a generic third-party module into the socket, you may not be able to communicate with it. But there's a good chance that the SSDs Apple uses have special firmware that's what they did with the 2013/2014 Macbook Pro/Air laptops, which use similar PCIe modules. In the Mac mini, the two separate drives used to mount in stacked SATA bays, similar to the stacked hard drive cages in towers.Īpple has a connector for the PCIe solid-state drive module on the logic board, which in Fusion builds is used for the NAND cache that's mooshed together with the traditional SATA hard drive to create the Fusion Drive logical volume. ![]() CoreStorage allows you to format the two physical devices as a single logical volume using Disk Utility the resulting volume is the Fusion Drive, which stores the most frequently accessed data on the SSD (such as the operating system and applications), and stores the less-used data on the platter drive. ![]() The Fusion Drive consists of two physical devices: A traditional spinny metal platter hard drive, and a solid-state NAND cache, similar to an SSD. Officially, no the drive you get when Apple builds the computer is the drive you're stuck with. ![]()
