If the performance is similar, is there any real reason for getting
a 2940 (assuming only one SCSI adapter)? Both the Symbios and 2940
drivers seem to support tagged queueing. Having purchased an 815-based
controller, I'm trying to come up with a decent reason for getting a
2940, aside from its name brand recognition and wider availability (you
can walk into most computer stores and talk about the 2940, but you'll
probably get blank stares if you mention the Symbios/NCR-based
controllers).
