7.4. SATA (Serial ATA) Disk Interfaces (J39 & J8)
The mITX-BW has an integrated SATA Host controller (PCH in the BW chipset) that supports independent DMA
operation on two ports. One device can be installed on each port for a maximum of two SATA devices via two SATA
connectors and one mSATA/mPCIe connector. A point-to-point interface (SATA cable) is used for host to device
connections. Data transfer rates of up to 6.0/3.0/1.5Gb/s are supported on all SATA ports.
Before installing OS on a SATA drive make sure the drive is not a former member of a RAID
system. If so, some hidden data on the disk has to 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:
2 to 4-drive RAID 0 (data striping)
2-drive RAID 1 (data mirroring)
AHCI (Advanced Host Controller Interface)
NCQ (Native Command Queuing). NCQ is for faster data access.
Swap bay support (not supported on mSATA/mPCIe)
Intel® Rapid Recover Technology
2 – 256 TByte volume (Data volumes only)
Capacity expansion
TRIM in Windows 7 (in AHCI and RAID mode for drives not part of a RAID volume).
(TRIM is for SSD data garbage handling).
