8.3. SATA (Serial ATA) Disk Interfaces (J10, J11, J12, J13)
The mITX-SKL-H supports an integrated SATA host controller (PCH in the CM236 chipset) that supports independent
DMA operation on six ports. One device can be installed on each port for a maximum of six SATA devices via four SATA
connectors, one mSATA connector and one M.2 SATA connector. A point-to-point interface (SATA cable) is used for
host to device connections. All SATA ports support data transfer rates of up to 6.0 Gb/s, 3.0 Gb/s, and 1.5 Gb/s.
Before installing OS on a SATA drive make sure the drive is not a former member of a RAID
system. If this is the case, some hidden data on the disk must be erased. To do this, connect
two SATA drives and select RAID in BIOS. Save settings and select <Ctrl> <I> while booting to
enter the RAID setup menu. Now the hidden RAID data will be erased from the selected SATA
drive.
Supported SATA features:
AHCI (Advanced Host Controller Interface) 1.3 and 1.3.1
2 to 4-drive RAID 0 (data striping)
2-drive RAID 1 (data mirroring)
3 to 4-drive RAID 5 (block-level striping with parity)
4-drive RAID 10 (data striping and mirroring)
2 to 4-drive matrix RAID, different parts of a single drive can be assigned to different RAID devices
NCQ (Native Command Queuing). NCQ is for faster data access
Swap bay support (not supported on mSATA)
