Interface

Only one S-ATA

2.0 port is available. Serial-ATA

connections boost the data rate theoretically up to 300

MB/sec. In addition it changes the parallel interface requiring 40 separate wires to a serial interface requi-

ring only 6 wires. The controller supports the A

dvanced Host Controller Interface (AHCI).

 If you use a mini S-ATA

card on connector J900 the hardware automatically switches from the

standard connector to the card socket.
