It has to do with the physical (mechanical) characteristics of the floppy.
The same disk that IBM used to call "1 MB" was 720k on a PC and 800k on a
Mac. Different encoding systems write differently to the same diskette. Why
they ever "advertised" the disks as being so large I'll never understand, but
the larger size was their "unformatted" capacity. The same thing holds true
with hard drives. Obviously a RAM card doesn't have these mechanical
limitations.
