You should be able to create a RAID on the Marvell ports if you want to test yourself, but speeds are terrible and the controller will drop drives from the array.But you can create one easily, maybe you just needed to update your BIOS first? I'd suggest not using those ports for RAID anyway, you can see my full review of controllers and C300 drives here if you want to get a better idea of how things perform on a Gigabyte board.http://forums.tweaktown.com/storage-devices-methods/41812-crucial-realssd-c300-128gb-single-vs-raid-w-marvell-ich10r-hpt-rr-640-review.html
