That's not the whole story - the interleave (which is set when a 3.5" disk is formatted, and can vary depending on the drive that formatted it) affects the performance of a given disk in a given drive, i.e. using a 'typical' IIgs 3.5" disk formatted with a 2:1 interlave in a UniDisk drive (which prefers a 4:1 interleave) will work but will be even slower than using a 3.5" disk formatted with a 4:1 interleave in the UniDisk 3.5. Using a 2:1 interleave formatted floppy in a regular (non-UniDisk) 3.5" drive attached to a IIgs would of course be faster than a 4:1 in a UniDisk attached to the same system.
