Thanks for the information, and its not a worthwhile tradeoff. I'll stick
with the 958. I just found it for $210 at TechData.
Actually, for most uses I find the FlashPoint cards are perfectly suitable.
While they don't have an onboard CPU, in typical usage they do not place enough
load on the host CPU to be significant. They generally perform slightly better
in elapsed time because there is lower latency between queuing a SCSI command
and it being started on the bus.
Also, there doesn't appear to be any information the the differential
version of the card. Not that I have any differential drives, I was just
wondering if I'm choosing the correct card. I wanted to make sure it was
as confusing as it is with choosing a 2940...
What information do you need about the differential version (BT-958D)? If you
have a differential SCSI bus, then you need the BT-958D. Otherwise, you need
the BT-958.
