You're welcome. I have a few years experience(and many frustrations) tinkering with these older systems, and reports of other people's work. Figure I should make use of it all when I can. As for the subject, I'm afraid we hijacked the topic from the original poster.Somewhat related to the original topic, the 2940U2B is known to not work in OS X, in case you plan to try later on.

I've been aware it's a U2B you have. U2B(and the retail U2W) gets a max of 80MB/s while the UW gets up to 40MB/s, both far above what you're getting right now, so it comes out the same. :)

Thanks Robert, greatly appreciate this. You are

the way, I don't know how it happened (probably
just used someone else's question subject) but
although my original subject was UW, I started my
q with "I am experimenting with an Adaptec
2940U2B SCSI card in a 7300 with a 405 MHz
processor. I have an 18G IBM HD connected to ..."
 The point is my card is a U2B. But this probably
makes little difference. What you say is
consistent with the lack of noticeable
improvement with other HDs and other SCSI card I
have used: all probably down to the old and
limited HDs I have...
