Poor Keanu Reaves gave up his childhood memories in Johnny Mnemonic to store something like 100GB of data in his brain. I don’t remember the Star Trek storage callout cause they were generally pretty good about just fabricating their own units for stuff (future sci-fi writers should take note, it’s always easier to make up units then deal with pedantic people on the internet).
indeed, most of their references to quantities of information use quads; there are a few using bytes though.
