This is an ok way to do things, but as Robert said, if you use hardware RAID
it dosent care *and* it's faster. One big advantage of RAID 5 is increased
read performance. This will be a lot less (if any) under software RAID. If
you use a software mirror for the C drive, DON'T even think about using IDE.
If you use IDE, both drives have to be on the same channel to set up a
mirror under NT and so there are double the amount of write commands which
slows down you system.
