Serial-ATA Connector (SATA1): It is for connecting a 2.5’’

hard disk to be served as your system’s storage. It can

support SATA II which features Data transfer rates up to

6.0 Gb/s (600 MB/s).

The controller contains two modes of operation—a
legacy mode using I/O space, and an AHCI mode using
memory space. software that uses legacy mode will not
have AHCI capabilities.
The AHCI ( Advanced Host Controller Interface) is a

programming interface which defines transactions

between the SATA controller and software and enables

advanced performance and usability with SATA. Platforms

supporting AHCI may take advantage of performance

features such as no master/slave designation for SATA

devices—each device is treated as a master—and

hardware assisted native command queuing. AHCI also

provides usability enhancements such as Hot-Plug.

Use the BIOS menu to configure your hard disk

to be AHCI compatible.

4-pin Serial-ATA Power Connector (SATA_PW1): It is for

connecting the SATA power cord.
