My impression is that in order of performance it goes
MFM -> DSSI

I would say DSSI, SDI, SMD and (depending on controller and drive) EDSI
are equal in performance.
and that the vS3500 was considered a performance
machine,
No. QBus VAXen are low end machines.
leading to the 3520 and '40.
The MV3500 on
one side and the VS35[24]0 on the other side are
completely different machines. The MV3500 is single CPU and all QBus
where the VS35[24]0 has 2 or 4 CPUs, a special MBus (?) and some sort of
QBus that AFAIK was only usable for a TQK70.
I would actually be surprised if DEC ever shipped a
vS3500 with MFM
drives.
My MV3500 came with MFM disks. (But was later extended with SMD and DSSI
by the previous owner.)
