I have a similar observation: 5.25" MFM floppies on a PC work faster
than 3.5" MFM floppies on the same PC. OK, the 5.25" floppy contains
"only" 1.2M, compared to 1.44M for the 3.5" floppy, but the
difference in reading speed appeared much greater than that. This
became quite obvious when I, a few months ago, backed up all my old
5.25" PC floppies on CD.
So I suspect this isn't as much a matter of MFM vs GCR, but rather
about sector interleaving on 3.5" MFM floppies, which appear to be
less than optimal.

The formatting speed shouldn't be such a concern -- after all you
usually format each floppy only once. The read/write speed is what
shoudl concern you.

So will I -- after all, part of the charm of a vintage computer is
to try to maintain it in original condition. Therefore my Apple II
will never get an Ethernet card either, even if one should become
available.
