Hi there,
Recently bought a new rig, with the ASUS P9X79 motherboard. 2 Samsung 830 SSD's and 3 * 2TB 5400 SATA disks. I wanted these 3*2TB disks in RAID to make 1 big 6TB volume.
Initially I configured the 3*2TB disks as RAID0 on the onboard Intel(R) C600 Series Chipset SATA RAID Controller. However all 6 SATA ports (2x6GB/sec for SSD and 4x3GB/sec for 2TB spinners) are all on the same controller. Not a big deal until I learned that SSD disks should be on AHCI and not RAID for best performance.
Solution: Configured the BIOS as AHCI and not as RAID and did not configure Intel ICH RAID on the 3*2TB disks but went to Windows7 striping instead.
ACHI Controller:
Stripeset:
Performance reading from E: (Windows7 stripeset) and writing to D: (SSD disk):
Other way around: reading from SSD and writing to Windows7 stripeset:
Conclusion: Stick to AHCI and use Windows7 striping! Abandon Intel Storage controller ICHx RAID and let Windows7 do the job!
