I'm looking for help figuring out why I'm getting poor performance with my Raid 10 array on a Asus P5K-E motherboard with the Intel Matrix ICH9R chipset.
If this question sounds familiar, I posted a similar one a couple of days ago, but deleted it when I decided to upgrade my bios and chipset drivers. But I have finished that now -- I have the latest BIOS and latest RAID drivers -- but I got no change in performance, so I'm asking the question again.
The first image below is the output from HD Tach, showing very erratic performance and generally low performance numbers. I don't even think the results are as good as a single drive.
The second image below is someone else's HD Tach results, with a somewhat similar setup. That is more what I expect to achieve.
The third image is yet another person's HD Tach results, also with a similar setup and also getting poor results like mine. But it appears that person never resolved the issue. http://forums.storagereview.net/index.php?showtopic=26731&st=0
The fourth image is from my old with a single 500 GB IDE drive. That's what I was getting before I invested in my fancy RAID setup!
The fifth image shows the Intel Matrix setup, with 4 500GB WD RE2 SATA drives in a RAID 10 array.
So I'm looking for help from anyone who has experienced similar issues or may be able to recommend some troubleshooting steps to solve the problem.
