I have x2 Hitachi T7K250's 250Gig in RAID 0 on an Intel ICH7R controller.
Stripe size, transfer speed (1.5Gbps vs 3.0Gpbs), and NTFS Cluster size doesn't seem to make a difference in terms of "real world" use and CPU utilization.
All the benchmarking tools report about an average of 5% for CPU utilization, but doing a simple file copy on the same RAID 0 volume in WinXP Pro drives that up closer to 25% (with nothing else running including antivirus) when looking at task manager performance.
It's a new system with a new volume, so I don't have all the extras loaded or a frag issue.
I'm also using the latest Intel ICH7R driver (1035).
Before downgrading the driver or running out and getting a different controller to test with, what is "normal" for real-world CPU Utilization and RAID 0 on this controller?
