    Slow RAID 1 on ICH10

    deadstick

      I recently built a system on an Asus P6X58D motherboard with the Intel ICH10 RAID controller. I've set up a RAID 1 array with two Seagate ST3320620AS 320GB drives, and I find it is atrociously slow: copying the contents of a DVD into a directory on the RAID takes almost three hours. Copying the same data onto a non-RAID drive on the same system takes 15 minutes. Principal questions:

       

      1. The drives are identical except that one has the 3.AAJ firmware and one has 3.AAK. Can this be the cause of the problem?

       

      2. Is it possible to use a disk cloning utility (like Seagate Disk Wizard) to clone the RAID array onto a non-RAID disk to serve as a bootable system backup in case troubleshooting of the array ends in disaster?

       

      3. Other suggestions? Thanks...
