Can't say much about 3.5" hard drives (the only really early ones I've
seen are standard ST505-type 2-cable interface).
But initially, the 3.5' floppies used a 26-pin interface (13 signal lines):
And of course, the drives spun at 600 RPM, which was really nice if you
were used to 8" or 5.25" drives. The Drivetek 5.25" high-capacity
drives would also spin at 600 RPM when a conventional floppy was
used--again, a nice feature.
