Also, what are some decent cached SCSI cards? I have an old VLB

You don't want a caching card. You'll just be spending your money on
nothing useful. The caching in a BSD unix is much more sophisticated
and highly effective already. If you couple that with a decent fully
bus-mastering SCSI card, you should have the ideal setup.
Caching controllers are of questionable value even in DOS systems
(software caching is reported to be just as fast, and significantly
cheaper). A modern unix works even better, because it can reallocate
memory pages intelligently and pretty much nullify the effects of the
hardware cache on the card.
