"I'm not sure how parallel vs. serial connection makes a difference in the speed listing"
Eh, back in the old days (well, maybe not THAT old), parallel device speeds were normally given in bytes per second, not bits per second - that was usually used for serial devices. The article claims the speed is 125-500 KiloBITS per second, but 3.5" floppy drives of old were usually rated at 500 KiloBYTES per second.
