He wasn't asking about the 1325.  

The RD54 is a Maxtor XT-2190.  MFM recording, with ST506 interface.  (Hint:
MFM is an encoding method, not an interface spec!)  

The DEC versions are supposedly modified for lower start-up current and a
quieter access mechanism (though mine, which has a DEC RD54 label, is certainly
noisy enough :-).  Other than that, they're identical and interchangeable with
the Maxtor-labelled drives.  

(Thanks to Terry Kennedy and Don Stokes for this information.)
