I think I agree, although more intelligent controllers on a 132MB bus
set is preferable to more disks on an 80MB bus. I think Marc's right in
that net throughput appears to be an even bigger issue.

Say 2 DPT's, okay. Now, as to the disks themselves. Does anybody know if
there's a disk that's intelligent enough to modify it's cacheing
algorithms for small-file transfers as opposed to large file work? It
seems to me that everybody's jumping on this so-called streaming-video
bonanza that's going to be here Real Soon Now, and that's strictly a
read-ahead situation.

I have had good results with IBM disks, but I've never benched them and
I don't know much of the insides.
