I have an Adaptec 1210SA RAID/SATA controller that i have used for quite a while. I just upgraded to two 74gb raptors (my 34gb raptors are for sale), and was curious if I would be better off running off of the Adaptec 1210SA controller of my ONBOARD RAID system (Abit AS8 motherboard). Will there be any difference at all? I would rather use the onboard RAID, only because I hate having the PCI slot taken up for the controller that essentially my motherboard can already do.
