I can correct you here. XP Pro and later do know about 'dynamic' disks 
and they can make mirrors from them. Booting from such disks is a kind 
pain in the ass but it works for RAID0, RAID1, RAID0+1 and RAID5 setup.

I can be wrong, I'm not a Win-fan, I just do know this exists. You can 
find details here:
