When I benched the drives were empty and found it pretty jagged and up and down.Then when I had some files filling about 10% of one partition and re-benched I found the line in that storage point (point the specific filled somehow partition is/starts) to be straighten.
The more filled Hdd the more the straight line is.

interesting ! will have to give it a go.

are you referring to PCI latency ?

No,PCI bus frequency.My board has an option for 33,36 and some higher I don`t remember.

2 X 74GB Western Digital Raptors in RAID0 on ICH5R con, Asus P4P800 E Deluxe, 3.4GHz Northwood, 2x512MB OCZ PC3200 Platinum rev 2. I am not overclocking at all, I have Memory Acceleration Mode enabled and Performance Mode set too standard.

I am using a 32KB stripe with a 4KB cluster size. I have used a 64KB stripe size on the ICH5R controller but I find I get better performance with a 32KB stripe. It has been recommended that your cluster size sould not be any smaller than a quarter of your stripe size, ie 32KB stripe size should not have a cluster size smaller than 8KB, however I find the 4KB stripe size works better than a larger one.

64K stripe - 4K clusters... computer in sig.

These aren't no Raptors, but I think these 2 Barracudas could take the Raptors.

Attached my Bench. I have an ASUS P4C800-E Deluxe with 2 Giga OCZ 3700 Platinum RAM and Intel P4 3.2e, two 75 Gig Raptors with 64 Kb stripe size, three partitions (C,E,F; Partition E is empty)

Here are my results with 2x 74GB raptors in raid 0 and 2x 73GB seagate cheetah U320 SCSI drives in raid 0:
