4.7 Serial ATA Hard Disk interface

The KTUS15 boards includes an onboard SATA interface depending on the configuration (refer to section

KTUS15/mITX Board configurations).

The SATA Host controller supports 2-port SATA II interface with data transfer rates of up to 3.0Gb/s

(300MB/s). The SATA controller supports AHCI mode and has integrated RAID functionality with support for

RAID modes 0 and 1.

The board provides two Serial ATA (SATA) connectors, which support one device per connector.

A point-to-point interface is used for host to device connections, unlike Parallel ATA IDE which supports a

master/slave configuration and two devices per channel.

The KTUS15 supports the following RAID (Redundant Array of Independent Drives) levels:

• RAID 0 - data striping

• RAID 1 - data mirroring

Limitations depending on Target Operating System apply.
