Serial ATA or Serial Advanced Technology Attachment is defined as a computer bus interface in order to connect the host bus adapters to the mass storage devices like hard disk drives and optical drives. Serial ATA was developed in order to substitute the older parallel ATA (PATA) standard (often termed by the old name IDE), providing different benefits over the older interface: decreased cable size and cost (7 conductors in place of 40), native hot swapping, faster data transfer through the higher signalling rates, and more proficient transfer through an (optional) I/O queuing protocol.
