I have two smaller fast hard drives and two larger slower hard drives that I would like to install in my new build using the Asus MB. I didn't have trouble putting the fast OS drives together in a RAID 0, but will the MB permit me to have the second pair of larger hard drives in a second RAID 0 array (not using a RAID card or anything)? If so, can someone briefly explain what I need to do? I haven't been to figure this out from the manual. And since I could still return the second larger drive, I don't want to open it up and just play around to see if I can make it work. Thanks for any info!
