Hi Paul, 

One problem, you can't make RAID volumes with just one disk, the
minimum is two.  Also you can't add disks to Promise RAID array's
Logical volumes later.  If all you have is one disk you're better off
not using RAID anyways as it may slow down disk data rates.
The rest sounds like a great idea, can't wait until I figure out what
I did wrong with mine.
