The Serial ATA (SATA, IPA: /ˈseɪtə/, /ˈsætə/ or /ˈsɑːtə/) computer bus is a storage-interface for connecting host bus adapters (most commonly integrated into laptop computers and desktop motherboards) to mass storage devices (such as hard disk drives and optical drives).

Conceptually, SATA (Serial Advanced Technology Attachment) is a 'wire replacement' for the older AT Attachment standard (ATA). Serial ATA host-adapters and devices communicate via a high-speed serial cable.

SATA offers several compelling advantages over the older parallel ATA/"EIDE" interface: reduced cable-bulk and cost (7 pins vs 40 pins), faster and more efficient data transfer, and the ability to remove or add devices while operating (hot swapping).

As of 2009, SATA has all but replaced the legacy ATA (retroactively renamed Parallel ATA or PATA) in all shipping consumer PCs. PATA remains dominant in industrial and embedded applications dependent on CompactFlash storage though the new CFast storage standard will be based on SATA.[1][2]
