Actually, 5.25” discs are only semi-floppy -the originals were 8”, otherwise a similar design.
Very true, but by the time home computing really took off, 8” discs were superseded by its younger brother. And a good thing too, as they would have required significantly more table space for the drive :D
I also remember owning a Zip Drive at one point. It was a doggedly slow parallel port high density drive which. at the time, had a capacity which rivaled cheap hard drives (Around 250Mb). I remember that I only ever ended up using it for backups due to the slow speed of parallel ports, though internal Zip drives fared much better.
That old Zip drive was left in the attic of my old home I believe. Another relic consigned to history.
