ya i've been reading RAID 0 is a better setup than single drives. i read an article on toms showing benchmarks between 2 WD raptor 150gb in raid-0 and 2 WD Caviar 400gb 7200rpm in raid-0. not alot of difference there. plus the price per GB is better than with raptors. i think i'll go raid and get a couple TBs.
