We have the Maxtor XT-8760 which has 620 meg formatted, and the Sigma 
controller, but Mike would like to use his existing RQD controller.  
I don't know of any that works with the RQD.
If you can afford the extra cost of the Sigma controller (~ $1200) the
combination is well worth it.  It is a pretty fast (ESDI) drive, and 
the controller has a 1 Meg cache to help out.  Pretty nice.
And, you basically plug it in and go.  The protocol on the bus side is TMSCP,
so it works fine with either VMS or Ultrix with no special drivers needed.
