KTD-N0886-E

SATA (Serial ATA) Disk interface

7.4
The KTQM87 has an integrated SATA Host controller (PCH in the QM87 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
four SATA connectors and two 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.
Supported SATA features:
2 to 4-drive RAID 0 (data striping)
2-drive RAID 1 (data mirroring)
3 to 4-drive RAID 5 (block-level striping with parity).
4-drive RAID 10 (data striping and mirroring)
2 to 4-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).
