Fusion Drive, a storage option on some iMac and Mac mini computers, combines a hard drive and flash storage in a single volume for improved performance and storage capacity. If your Fusion Drive appears as two drives instead of one in the Finder, it's no longer working as a Fusion Drive. This can happen after replacing either drive of your Fusion Drive, or using software to intentionally split them into separate volumes.
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.
② Only a hybrid hard drive that is made by Apple or made and used in a Mac can be called a fusion drive. The fusion drive is unique to Apple. ③ The fusion drive is in-built when you order a Mac, and usually there are four selections: 1T fusion drive, 256G SSD, 512G SSD, and 1T SSD. When you purchase a Mac with an optional Fusion Drive (currently, a Fusion Drive is a $250 upgrade to the $799 Mac mini), the OS and all of the applications that ship with a new Mac are loaded. The most important thing to do if your Mac has a Fusion Drive: Back up your data The Fusion Drive combines data on an SSD and hard drive, so the loss of either is a huge problem.
