KTD-N0882-D
6.3 SATA (Serial ATA) Disk interface
The KTQ87 has an integrated SATA Host controller (PCH in the Q87 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 five SATA connectors and one mSATA 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.
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.
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).
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:
SATA0, SATA2, SATA3 , SATA4, and SATA5. (SATA1 used by mSATA)
