wikiSerial ATA Standards
Serial SATA (SATA, S-ATA/Serial Advanced Technology Attachment) is a serial interface to transfer data from computer systems to storage devices such as hard drives or DVD drives. SATA is the successor to the earlier parallel IDE / ATA interface. SATA hard drives can also be connected to SAS controllers not only to SATA controllers.
