Because I have an ASUS p6T (regular version), and I don't have any SATA III ports. I'm looking to buy 2x 120GB OCZ SSD's that are SATA III compatible and put them on that RR card. What i'm not sure of, is would I be able to have a RAID array on my ICH10R simultaneously as having a RAID 0 array on the Marvell 9128 RR card?
Currently I have a RAID 0 setup already going on but I wanted to keep that all on my ICH10R.
The answer to the most basic question is "Yes." Each controller can have a RAID array, or more than one, if all of the drives in the array are on that controller.
But there is a more important question here, "Why?" Buy a 240 GB SSD, or the nearest size in that same line. Tom's has consistently stated that larger drives in the same line run faster, probably because they use more channels. Let the manufacturer do the work.
