What is SATA?




Serial ATA (SATA or Serial Advanced Technology Attachment) is a computer bus interface for connecting host bus adapters to mass storage devices such as hard disk drives and optical drives. To replace older parallel ATA (PATA) standard ( which is often known by old name IDE), Serial ATA was designed offering several advantages over the older interface: reduced cable size and cost of 7 conductors instead of 40, native hot swapping, faster data transfer through higher signalling rates, and more efficient transfer through an (optional) I/O queuing protocol.
