Ok i just got a rosewill raid controller, because my mobo dsnt have onboard raid support. The system is currently running off a 250g drive, but i want to add two new drives in raid 0. I was originally going to just install them and keep the 250 as my boot drive and just put games on the new drives, but now i am thinking about doing a clean install. Will the games i put on the new drives run faster if i keep the 250g as a boot drive or if i do a clean install and have xp on the RAID?
