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.
