Between the 3", 3.25", and 3.5", the 3" does seem to be the best.
BUT, THAT isn't what decides what becomes the defacto standard.
Dysan thought that it was software availability.
Tony seems to think that quality is a factor.
But it all finally comes down to what do the BIG companies choose.
FWIW, some Barbour raincoats have inside pockets large
enough to take 8"
floppies (unfolded, of course).
Somewhere I have another Epson 5.25" drive. It's odd. It's got 2
logic-level cables going to it (i.e. not counting the power cable, which
looks conventional), one 34 pin, the other 20 pin. It's in a case about
the same size as the Epson TF20 with a controller board and a PSU. The
controller has what seems to be an MFM _hard disk_ conteoller chip on it.
the interface to the drive looks very much like ST506.
