Just built a new system. Put in dual 36GB Raptors SATA. RAID0 config on my Neo2 K8N Platinum. In SiSoft Sandra, I'm only seeing 70MB/s! Also on HDtach, the graph is very spikey, fluctuating violently from ~110MB/S down to 40MB/S.
I left the stripe size default, which if I recall correctly was 32KB, but possibly 64KB.
