The big ones are not rigid, they flop around. The smaller ones (the save icon ones) have a rigid plastic case that does not flop. Inside both kinds is a floppy disk though, hence them both having that name. “Hard disks” have metal platters that decidedly do not flop, in or out of their case.
I’m confused. Those all look equally hard to me

The left two are bendable like a fedex envelope, the one on the right is hard plastic
It might help to take a closer look at the height of each disk casing to guess why two are called floppy and one hard.
