SATA - Computer Definition
(Serial ATA) The standard hardware interface for connecting hard disks and CD/DVD drives to the computer. SATA was introduced in 2002, and nearly all computers use SATA drives. External SATA (eSATA) and Powered eSATA Although most SATA drives are internal and cabled directly to the motherboard, computers often have "eSATA" ports on the outside of the case for plugging in an external SATA hard drive. If the port is "eSATAp" (powered eSATA), the external drive derives its power from the computer rather than a wall outlet. SATA, PATA and IDE SATA is the faster serial version of the original parallel ATA (PATA) interface. Both SATA and PATA are "integrated drive electronics" (IDE) devices, which means the controller is in the drive, and only a simple circuit is required on the motherboard. Although SATA is an IDE technology, "IDE" refers to PATA (for details, see IDE and AHCI). See mSATA.
