Poor ICH9R RAID performance after Win7 reinstall

[mistahmagic]

I'll let the pictures speak for themselves. This causes mp3s to pause completely for a couple seconds, unbearable stuttering in games installed on the RAID, etc. I am running Win7 x64 RC1. I'm using the latest Intel Matrix driver for Win7 x64 from their website. Gigabyte P35-DS3R. I'm not sure, but the pictures actually look like one of the drives keeps dropping out?..

EDIT: Neglected to mention that the drives are in RAID 1. One is an old Maxtor, one is a Seagate. Both drives check out after running tests, this appears to be purely a configuration issue..

Other notes: I didn't have write behind caching enabled before, not using it now. On the same day that I reinstalled Win7, I actually reloaded my BIOS defaults as well, and re-tweaked my overclock. Is it possible that a motherboard option has something with this? Please help

This one was very slow and only had one peak!

Results of my single WD Black 650gb drive, also on one of the ICH9R ports, for comparison:

Those 250 gb drives are pretty old, so failure is a possibility, but this was a non-issue on my previous Win7 install.

Things that have no effect: Changing between RAID and AHCI modes in bios, enabling/disabling write behind cache, defrag, using a slightly older version of the intel storage driver from a few months back.

Running a verify/repair in matrix storage manager now, even though it says the volume is okay.

I can't believe not one person has a recommendation for anything to try...Someone? This is [H], don't disappoint me

Even a 320kbps mp3 is only running at 0.04MB/s. Even at the performance level you have it should not affect mp3 playback.

You could try resetting your CMOS to see if that helps at all. I would recommend a cleared CMOS, reformat, and clean install personally.
