I'm using a SUN SMD-4 (the 7053) with a CDC 9720-1230 drive and I've never
had any problems, so the SMD-4 does handle 3 MB/s transfer rates.  I know
the documentation for the SMD-4 says that it will only support up to 2.4
transfer rates, but I called SUN technical support and they said it really
does support 3.0 transfer rates.  I guess the most convincing argument is
the fact that it works fine.
