3.5-inch and 5.25-inch drives connect to the floppy controller using a 34-conductor flat ribbon cable for signal and control. Most controllers support two floppy drives, although the Shugart standard supports up to four drives attached to a single controller. A cable could have 5.25-inch style connectors, 3.5-inch style connectors, or a ...
When the controller and disk drive are assembled as one device, as it is the case with some external floppy disk drives, e.g., Commodore 1540 and USB floppy disk drives, [27] the internal floppy disk drive and its interface are unchanged, while the assembled device presents a different interface such as IEEE-488, parallel port or USB.

[citation needed] With increasing sales of microcomputers having built in floppy-disk drives (FDDs), HDDs that would fit to the FDD mountings became desirable. Thus HDD Form factors, initially followed those of 8-inch, 5.25-inch, and 3.5-inch floppy disk drives. Because there were no smaller floppy disk drives, smaller HDD form factors ...
Circuit components of the external USB SuperDisk for Macintosh. The drive itself is the same size as a standard 3.5″ floppy drive, but uses an ATA interface. On the right is the USB-to-ATA adapter, which plugs into an intermediate fan-out and power supply daughterboard that is inside the rear of the Mac drive's casing.
