Feb 03, 2020 Choose Apple menu About This Mac, then click Storage. If you see a drive labeled Fusion Drive, your Fusion Drive is working and this article doesn't apply to you. If you have a Fusion Drive that has been split, you should see two drives. One of them should be labeled Flash Storage, with a capacity of 24GB, 32GB, or 128GB.
Yes you can. OWC (www.macsales.com) makes kits if you want to do-it-yourself. However considering how difficult it is to do I'd recommend one or two options.
Fusion Drive remains available in subsequent models of these computers, but was not expanded to other Apple devices: the latest MacBook and Mac Pro models use exclusively flash storage, and while this was an optional upgrade for the mid-2012 non-Retina MacBook Pro discontinued by Apple, it will replace the standard hard disk drive instead of.
The ‘#’ will be a number which is assigned to each drive by OS X. Make a note of the mount points for both the HDD & SSD that you wish to create the Fusion Drive with, you’ll need them shortly. We will now create the logical volume group using Core Storage, this will perform as a container for the drives.
Apr 06, 2013 I have a Mac mini with 128gb SSD and the standard 500gb HDD - I have my apps and OS on the SSD and iTunes music folder (130gb) on the HDD. All my movies are on external drives. What would be the benefit of restoring and creating my own fusion drive?:confused: TA:).
Oct 25, 2012 “What is Fusion Drive?“, in simple sentence, its a combination of HDD & SSD into one Storage Drive. This technology in new iMac released this 2012, enables you to install OS X and other applications on the primary SSD Flash Storage which brings best and faster access overall.
Install Mac Os On Flash Drive
Either:
Buy the kit from OWC (you don't indicate whether your iMac is 21.5 or 27') Here is the kit for a 27' https://eshop.macsales.com/item/OWC/K27IM12HE2TB/ this kit has everything needed, using other brands of SSDs may or may not work and definitely do not include all the necessary parts and instructions. Once you have the kit, have a local AASP do the work due to the difficulty. Apple Stores will not do it!!!
Next option is to simply buy an external SSD and then install Mac OS on it and migrate your data to the external SSD. Then reformat the internal HD and use it for additional storage. The advantage of this is it's likely less expensive, much easier to do and provides additional storage.
BTW, here is the video to install one in a 2015 27' iMac: https://eshop.macsales.com/installvideos/imac_27in5k_14late_hdd/iMac17-1/
