I am a speed freak when it comes to my favorite past time. I have purchased a new MSI Neo2 FISTER mother board and am going to use two Western Digital Raptor 10,000 RPM hard drives in raid 0, I have 2 gigs of pc2100 RAM, and a P4 2.53/533 fsb prosessor, that should fly pretty good the best I can figure. My problem is that the WD hard drives are only 36 gigs in size. If I have them raid 0, can I still use my ultra ATA EIDE hard drives for storage? Or once I set the system for raid on the serial drives does that render my EIDE ULTRA ATA drives unuseable?
