I was wondering what the best way to set up my hard drives to make my system the most efficient. currently, i have x 150 gig Sata II 7200 rpm hard drives set up in a striping raid. I also have a 320 gig hard drive with most of my files. although i do install programs and keeps files on the main array. i heard if you install programs on one hard drive and keep the saved content on another the system will be faster? also i like to re format system a few times a year to keep it clean and fast running. also i've beenign thinkin of goin to 10000 rpm hard drives, possibly the 2 36 gig ones and raiding that and keeping most of my files on the 320 gig hard drive. is this a better way of going about things?
