Can I make a RAID-0 array with unequal sized drives using the Promise
contoller?

I can get away with this in the server/SCSI world with the caveaet that the
array can only be as large as the smallest drive; since I want to stripe a
40 and a 20, I'd only really get 40 gigs of striped space, 20 gigs of the 40
being lost.

I've RTFM and it doesn't say anything about size requirements.
