Normally, I'd also agree with this. However, a friend of mine built a NAS using the 3ware card and 11 200gb WD drives in a RAID5 config and can sustain 85mbit/s *write* (the test was several hours long). I suspect it would do even more with a gig-E card. Of course, that test would be fairly meaningless when you're doing something like a mail spool, but it proves the application should drive the method.
