Just wanted to provide a little more information now that I have my RAID up and running (and my system is FAST now!!!)
8gig drive set to master on IDE1
CDRW drive set to master on IDE2
30gig drive set to master on IDE3
30gig drive set to master on IDE4
Zip drive running on my ISA SCSI card
When I first set up the RAID my 8gig drive was still showing as drive C and the RAID was D... then I copied everything over to the RAID, set it to be the first boot device and now my RAID is drive C and the 8gig is drive D Then I set my CDRW and Zip to use the same drive letters they were using before so I don't have to hack the registry for them (although I do need to hack it for all those things I moved over from the used-to-be D and E drives, onto the new C)
As some additional information, the RAID drives I'm running are IBM Deskstar 75GXP 30gig ATA100 7200RPM... independently they'd get a Sandra benchmark of around 23,750... when in the RAID I get about 44,000
There's just something really nice about double-clicking on an icon and the program basically instantly coming up! Sandra used to take a good 3-5 seconds to load... now that I'm on the RAID, I click and it's loaded immediately!
