I disagreed strongly - I think X-per-second should be decimal, to correspond to Hertz. But for quantity, binary seems better. (modern CS papers tend to use MiB, GiB etc. as abbreviations for the binary units)
Fun fact - for a long time consumer SSDs had roughly 7.37% over-provisioning, because that's what you get when you put X GB (binary) of raw flash into a box, and advertise it as X GB (decimal) of usable storage. (probably a bit less, as a few blocks of the X binary GB of flash would probably be DOA) With TLC, QLC, and SLC-mode caching in modern drives the numbers aren't as simple anymore, though.
RAM had binary sizing for perfectly practical reasons. Nothing else did (until SSDs inherited RAM's architecture).
We apply it to all the wrong things mostly because the first home computers had nothing but RAM, so binary sizing was the only explanation that was ever needed. And 50 years later we're sticking to that story.
Just later, some marketing assholes thought they could better sell their hard drives when they lie about the size and weasel out of legal issues with redefining the units.
