I have the opportunity to buy two 74 gb 10k Raptors from a friend for 75$. I currently use a 1TB Hitachi Deskstar <16 mb cache> as my system drive and my mobo is a 680i SLI EVGA. Is this a good idea? Would Raid 0 give me better boot times? I currently am using Windows 7 Enterprise 64 bit 90 day trial while i wait for my upgrade disc.
