发帖数: 3896 | 2 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. Serial ATA was designed to replace the
older ATA (AT Attachment) standard (also known as EIDE), offering several
advantages over the older parallel ATA (PATA) interface: reduced cable-bulk
and cost (7 conductors versus 40), native hot swapping, faster data transfer
through higher signalling rates, and more efficient transfer through an (
optional) I/O queuing protocol.
