Yes, but that assumes you've got (e.g., 30G) of RAM lying around  :>

The whole point of the disk drive is as "slow (inexpensive)
memory" in places where *fast* (expensive) memory is not
necessary!

(It's also a win in that it allows for reducing capabilities
in the processor, etc. -- i.e., so you don't need DIRECT ACCESS
to all that memory)
