I've been using Super PC-Kwik, from Multisoft, Beaverton, OR, and have
been quite pleased.  My computer is a Toshiba 1100+ Laptop with very
slow floppy drives, so the speedup is a major help.  The program has
almost every conceivable option for various hardware configurations,
cache granularity, drives to cache/not cache, etc.  The program
includes a "measure" command that tells you the cache hit rate, which
seems to vary from around 40% to over 80% depending on what I'm doing.
One caveat: you do need to be careful about configuring the whole
system so that the cache and your application aren't fighting over
memory - i.e., you should either have a big cache and few buffers, or lots
of buffers and a small cache, but not both, or you actually end up
with worse performance.

Multisoft's number is (503)642-7108.  The program seems to be sort of
hard to find, but I think it's worth looking for. (I have no
connection with this company.)
