The Acronis recovery CD that it makes for you has the driver for your RAID controller, and can restore at high speed.
Doing a Ghost or DriveImage XML restore relies on the BIOS extended INT13h extensions, which the ICH9R supports, but at a maximum speed of about 2 MB/sec. Be prepared to wait a while for the restore to take place.
If your RAID loses a drive, you'll get a new drive, re-set up the RAID, then run the recovery CD from one of these programs and restore the image to the RAID.
