SATA
serial ATA is a computer bus that uses a data interface for connecting mass memory storage devices such as hard disks and optical disks. It achieves higher performance than ATA controller because the transmission is performed serially at a high frequency and supports disconnecting and connecting the machine while the computer is running (Hot Plug). Developmentally, there are several specifications that differ in transfer speeds e.g. SATA-1, SATA-2, SATA-3.
