If you're devoted to the idea of buying hardware to solve the problem, I'd first look at adding enough RAM to put everything on a RAMdisk. That would speed the I/O up dramatically, though I/O may not be your problem.

Consider profiling to see what the slow parts of your program are; that should help you figure out whether speeding up I/O will help very much.
