With memory prices dropping, it makes some sense to use a RAMdisk as the
paging device on a high performance system. The RAMdisk can use slower,
less expensive memory. Also, the main memory bus can be driven much faster
if it is known that there will be no more than, say, 500 memory chips on it.
The RAMdisk, on the other hand, could have more than 50,000 chips.
