Which is exactly the point :-) . SCSI cards, unlike IDE subsystems,
are supposed to work by themselves and ease the burden
on the processor. This is considered a "good thing".

Like many others, I've not had problems with the Adaptec 2940 series.
I also like a CMD card that I have somewhere; it has a 72 pin SIMM
slot to increase the cache; at one point I had a 64MB SIMM there and
it helped the web server a lot.

But the nicest one I've seen is the ibm ultra-160 raid controller
in our smp netfinity Linux server. It absolutely rocks.

Do note that I tend to use HP, Sun, DEC or IBM scsi cables.
Mac cables have given me trouble before.
