SATA stands for Serial Advanced Technology Attachment (SATA) and is a storage interface for hard-disk drives and ATAPI devices. SATA replace the slow, and clunky Parallel ATA (PATA) interface used on older EIDE disk drives.

The standard for SATA, when compared with PATA, offers lower signaling voltages and reduced pin count, is faster and more robust, and has a much smaller cable. It is also completely software compatible with Parallel ATA and provides backward compatibility for legacy Parallel ATA and ATAPI devices.
