7.4. SATA (Serial ATA) Ports (J12, J18)
The mITX-BDW-U has an integrated SATA Host controller (PCH in the BDW-U 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 M.2 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 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 M.2)
 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).
