Then use the remaining space on the drives however you see fit (like mirroring the remainder of the 80GB drives, and perhaps the 36 and some of the 40). That would be unsustainably complicated for a production system, in my opinion. Drives are pretty cheap--just buy two 250GB drives and mirror them, or buy two more 80GB drives and get rid of the 9, 36, and 40.
