SATA (Serial ATA) Disk interface
KTQ87 / KTH81 has integrated SATA Host controller (PCH in the Q87 / H81 chipset) which supports
independent DMA operation on 6 / 4 ports. One device can be installed on each port, via point-to-point
interface (SATA cable), for a maximum of 6 / 4 SATA devices. On the mITX the SATA ports are available as 5
/ 3 SATA connectors + 1 mSATA connector and on the Flex the SATA ports are available as 6 / 4 SATA
connectors.
All the SATA ports on the Q87 support SATA Gen3 (6.0/3.0/1.5Gb/s) are supported, while two SATA ports
on the H81 supports Gen3 and the remaining two ports support Gen2 (3.0/1.5Gb/s).
Note: 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
RAID data will be erased from the selected SATA drive.
Note: KTH81 do not support RAID.
The SATA controller supports:
2 to 6-drive RAID 0 (data striping)
2-drive RAID 1 (data mirroring)
3 to 6-drive RAID 5 (block-level striping with parity).
4-drive RAID 10 (data striping and mirroring)
2 to 6-drive matrix RAID, different parts of a single drive can be assigned to different RAID devices.
AHCI (Advanced Host Controller Interface)
NCQ (Native Command Queuing). NCQ is for faster data access.
Swap bay support (not supported on mSATA)
Intel® Rapid Recover Technology
2 – 256TB 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).
Sata connector pinning: SATA0, SATA1, SATA2, SATA3, SATA4 and SATA5. (SATA1 used by mSATA on mITX)
