I've got to strongly disagree with Dan here.  OS X, like all Unix-y
operating systems, manages RAM in such a way that it is almost constantly
accessing swap space on the hard drive regardless of how much physical
memory you have.  In such a case one of the most important variables
affecting overall system performance is seek speed on the swap drive.  This
is just OS Theory 101.

Allan's Powerbook has an 80 Gb hard drive in it (upgraded from the original
40 Gb).  You can hardly get drives that small anymore.  A new one will have
a much lower seek time along with higher throughput and a larger,
better-managed onboard  cache.  For the $100 or so,max, that a new drive
will cost, that's the thing that will make the second biggest speed
improvement for the least cash, after more RAM.
