This video, about floppy disks, is a little bit longer and in-depth than their previous one about cassette tapes. The 8-Bit Guy and friends (I'm pretty sure they don't call themselves that…) goes through how many tracks each floppy have, how many sectors they have, and how that varies per-manufacturer (including the technical reasons of how and why they are formatted incompatibly).

The 8-Bit Guy likes to go through a bunch of hardware, spanning the gamut of Atari, Commodore, Apple, IBM PC, and others, and explain their history. The most interesting part of this video, to me, was his explanation of why the Commodore floppy drive was so much larger than its competitors, and what it meant for performance.
