   Historically, most SSDs used buses such as SATA, [19] SAS, [20] [21] or Fibre Channel for interfacing with the rest of a computer system. Since SSDs became available in mass markets, SATA has become the most typical way for connecting SSDs in personal computers; however, SATA was designed primarily for interfacing with mechanical hard disk drives (HDDs), and it became increasingly inadequate ...

   According to the paper, [5] 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. 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 ...
