Fusion drive is Apple Inc's name for its implementation of a hybrid drive. Apple's implementation combines a hard disk drive with a SSD and presents it as a single Core Storage managed logical volume with the space of both drives combined.

Some Mac computers such as iMac and Mac Mini provide the option of Fusion drive, which is an integration of solid-state drive and hard disk drive. The former provides high-speed read-write performance while the latter high storage capacity. The speed of a Fusion drive is greatly faster than an HDD but comparatively slower than a pure SSD. The consolidation of the two drives is quite effective in maintaining an equilibrium in cost and benefits (speed & capacity) to Mac users.
