i second what stickybytes has said. it will depend on your OS, your sytem, and when you stop timing. i.e. in Win2K do you stop when the screen changes from the loading to the blue default screen, or do you wait until the cursor stops doing it's hourglass thing. and do you have additional SATA controllers attached to your mobo? or have you stripped your system down to get the absolute fastest time possible
anyway. i don't have boot times 'cause i never actually bothered to time it, but I'm running a single Raptor on the Nforce SATA connection on the Asus K8N-E Deluxe with Windows2000. I just got it installed, and right now my feeling is that the overall system is a little faster, but it wasn't really the night and day difference I was expecting. I still haven't installed UT2004 yet, so I don't know if that will load faster or not. Frankly, I got the Raptor mostly because it was cool anyway. I did decide that RAID 0 wasn't cost effective enough though.
