> Be aware that it is bits, so 62.5kb

Ok, I’m not normally one to be the pedantic bits/bytes guy, but if you’re gonna go and make a bit/byte “clarification” you need to get the annotation correct or you'll just confuse everyone.

It’s 500kb (small b for bits) and 62.5kB(capital/big B for bytes).

Shouldn’t it actually be KB or even KiB?

If we're playing actually, then it's a speed not a quota, so whatever the correct value it should be suffixed with "per second".

Good point!

K is for Kelvin, so probably not. kB or KiB, depending on intent.
