True, the mechanics are about the same, and the auto eject mechanism shouldn't influence writing to or reading from the diskette. But 20% possible difference in rotational speed is still about 60 rpm, which is way out of the range of what a run-of-the-mill floppy drive is capable of through regulating it's speedpotentiometer (tried it years ago. I used to dabble with an Atari ST - which BTW they used to call The Cameleon for being able to write any format to diskette ;-) -, we tried reading Mac diskettes only to find that after a while of taking the abuse, the floppy drives would give up). And writing more bits to the outer tracks than to the inner tracks, means more sectors on the outer tracks and less on the inner tracks. And this is where I think the big difference lies.
