6.5 SATA (Serial ATA) Disk interface (J21 – J26)
The KTQM67 boards have an integrated SATA Host controller (PCH in the QM67 chipset) that supports
independent DMA operation on six ports. One device can be installed on each port for a maximum of six
SATA devices. A point-to-point interface (SATA cable) is used for host to device connections. Data
transfer rates of up to 6.0Gb/s (typically 600MB/s) on SATA0 and SATA1 and 3.0Gb/s (typically
300MB/s) on SATA2, SATA3, SATA4 and SATA5.
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 <Ctrl> <I> while booting to enter the RAID setup menu.
Now the hidden RAID data will be erased from the selected SATA drive.
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.
Hot Swap
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).
The RAID (Redundant Array of Independent Drives) functionality is based on a firmware system with
support for RAID modes 0 1, 5 and 10.
SATA connector pinning:
The pinout of SATA ports SATA0 (J21), SATA1 (J22), SATA2 (J23), SATA3 (J24), SATA4 (J25) and
SATA5 (J26) is as follows:
