- That is probably true. ISA SCSI boards don't vary much as far as
- throughput is concerned. You could get faster response times by
- using a caching controller, but your transfer rate probably would
- stay about the same. It's also likely that your drive already has
- its own cache.

- While it is true that drives with faster RPM in general give better
- performance, I doubt that one would help your situation. The best
- thing you can do to improve performance is to get either an EISA
- or VESA Local Bus system with a corresponding controller. The ISA
- bus is just not up to consistently high transfer rates. It's a
- circa 1984 technology and it is almost 1993. It is unfortunate that
- while performance for most things have increased dramatically, PC
- users are still for the most part stuck with a nearly decade old
- bus design.
