I once read about an OS that booted before the floppy had fully spun up, and was inspired, only to discover when I tried it myself that at computer speeds, even with the floppy seek to load a kernel from a FAT image, it's actually rather easy.

(to be fair, I think media corruption was more common back then, so boot-time file system checks and other sanity checks may have been what kept mainstream boots slower?)

Loading speed for cassette tapes and floppy disks was measured in bits per second at the time (usually between a few hundred to a few thousand bps), that was just what the hardware could handle, even without expensive error correction ;)
Makes a lot of sense, too. Why would you even want to load data faster than you can read it on screen, or print it out on paper? That's just a waste for such a minor increase in overall speed.
