Data movement is based on access patterns: if data has been on the HDD and suddenly becomes frequently accessed, it will usually get moved to the SSD by the program controlling the Fusion Drive.More frequently accessed data is stored on the SSD and the larger, less frequently accessed data stored on the HDD.A portion of SSD space is used as a write-back buffer to absorb incoming write traffic, which hides perceivable latencies and boosts write performance.The SSD and the hard drive are logically merged into a single block device managed by the operating system, which is independent of file systems and requires no changes to applications.According to the paper, this hybrid storage system unifies a high-speed SSD and a large-capacity hard drive with several design considerations of which one has been used in the Fusion Drive. It has been reported that the design of Fusion Drive has been influenced by a research project called Hystor.

As of November 2021, no Mac offers a fusion drive.Īpple's Fusion Drive design incorporates proprietary features with limited documentation.

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 complementing it in the fashion of Fusion Drive. The Fusion Drive was announced as part of an Apple event held on October 23, 2012, with the first supporting products being two desktops: the iMac and Mac Mini with OS X Mountain Lion released in late 2012. In software, this logical volume speeds up performance of the computer by performing both caching for faster writes and auto tiering for faster reads.

For example, if spreadsheet software is used often, the software will be moved to the flash storage for faster user access. The operating system automatically manages the contents of the drive so the most frequently accessed files are stored on the faster flash storage, while infrequently used items move to or stay on the hard drive. Apple's implementation combines a hard disk drive with a NAND flash storage ( solid-state drive of 24 GB or more) and presents it as a single Core Storage managed logical volume with the space of both drives combined.
