Another route might be inspiration from exponential math notation. Traditional kilo/mega/giga/tera-bytes are just 2 to the power of 10, 20, 30, 40, etc.

So perhaps a terabyte could be a "bin fourty", or a "two-to-fourty", etc. (Although as it linguistically relaxes into Tootafortie, it'll sound goofy too.)

doesn't work for non english languages

What a vague and bizarre complaint.

You're saying that units-of-10 in English (and using Arabic numerals) will "not work" for other languages, when the international status-quo we're complaining about is already powers-of-1000 in Greek which are then mutated with Latin?

Why do you think there's a (new) problem?
