How large are the disks?  AFAIK a rebuild doesn't take into effect the size 
of the data, just the disks themselves.  A raid 5 build takes 90 minutes 
on 250gig disks.

Plus, if you're rebuilding while the OS is running, only a certain 
percentage of the system resources are used for rebuilding.  By default I 
think it's only 30% of the cards resources are used.
