Hi,
A late response to this.
I am running a GA-P67A-UD7-B3 with a pair of WD2002FAEX drives on the Marvell ports, configured as RAID1.
The drives are accessible and the Marvell RAID Utility claims that all is well.
However, I am getting very large disk IO on my C: drive by the mvraidsvc.exe process and the Marvell Tray (but strangely, no reads from the Marvell array).
I also get occasional CPU spikes and system freezes of 2 to 10 minutes, over a period of 1 hour or so.
After a few weeks of debugging, re-installing Windows, disabling services as per BlackViper, and many searches around the Marvell 9128 controller, I think I will next back up the Marvell array and revert to simple disks under ACHI, removing the Marvell raid driver and RAID service processes and setting up a backup service to external SATA disks.
I feel a friustration at having 2 Intel Sata3 ports which I have to use for the boot disk, and Sata3 disks running off Sata 2 ports. I tried installing Windows on a disk on port 2 and hit lots of problems.
The ports are:
0: WD500 boot disk
1: Asus DVD drive
2&3: WD2003FYYS RE4 in RAID1
4&5: Seagate ST3 1500 in RAID1
6&7: Marvell: WD2002FAEX in RAID1
eSata: various disks.
