SATA replaces the older ATA hard drive interface. Hard drives that use the SATA interface have distinct advantages over ones that don't. The SATA interface provides faster transfer rates, thinner and more flexible cabling, and easier plug-and-play connections. Most SATA-based hard drives don't have any jumpers that need to be set. They also don't create aprimary/secondary relationship between drives, as other methods did. Each hard drive operates on its own independent SATA channel. mikroman6 / Getty Images There are currently six versions of SATA: SATA Version Speed Notes SATA 1 and 1.5 1.5 Gbits/s SATA 2 3 Gbits/s SATA 3 6 Gbits/s SATA 1.5, SATA 2 and SATA 3 devices are interchangeable. You can connect a SATA 1.5 hard drive to a SATA 3 interface, and the drive will work just fine, although only at the slower 1.5 Gbits/s speed. The reverse is also true. If you connect a SATA 3 hard drive to a SATA 1.5 interface it will work, but only at the reduced speed of the SATA 1.5 interface. SATA interfaces are primarily used on drives and removable media drives, such as CD and DVD writers. SATA Versions Used in Recent Macs Apple has used various types of interfaces between Mac’s processors and its storage system. SATA made its Mac debut on the 2004 iMac G5 and is still in use on the iMac and Mac mini. Apple is moving to direct PCIe interfaces in order to support faster Flash-based storage, so the days of the Mac using SATA are likely numbered. If you're wondering which SATA interface your Mac uses, you can use the table below to find out.

Since no Mac is factory-equipped with an eSATA (external SATA) port, these drive enclosures operate as a USB to SATA converter, or Thunderbolt to SATA converter. When purchasing an external drive enclosure, make sure it supports SATA 3 (6 GB/s), and is the correct physical size to hold a desktop hard drive (3.5 inches), a laptop hard drive (2.5 inches), or an SSD that is commonly available in the same laptop size (2.5 inches).
