For SSDs:
Read Ahead = off
IO = Direct (not cached)
Write back = enabled.
Drive cache = disabled

Make sure you've secure erased the SSDs first, you'll need to do this on the Mobo SATA ports
Also after setting RAID reboot
Seems to work best for benchies.

Consider a 64k stripe size.

yes, 64 or 32 is best. Also Fastpath if your a nut :)

Faspath always better than GardenPath to be led down :D
