Serial ATA (SATA, Serial Advanced Technology Attachment) is new generation a harddisk interconnect. SATA replace parallel ATA technoloy. The Serial ATA (SATA) have two separate connectors, one connector for the data lines and one for the power lines.
SATA pinout
Pin Name Function
SATA uses a 4 conductor cable with two differential pairs [Tx/Rx], plus an additional 3 grounds pins and a separate power connector. SATA runs at 150MBps(SATA/150), 300MBps(SATA II), or 600MBps transfer rates. Faster SATA implementations are backward compatible with older devices. 8B/10B encoding used for data transfers. Maximum unshielded cable length is about 1 meter. eSATA shielded cable may be up to 2 meters length.
