Disk Capacity....

Areal comparisons don't hold, thermal expansion alone prevents just
increasing capacity physically. It's not a coincidence the bigger drives
are physically smaller.

Encoding for modern data densities has long abandoned the simplistic
schemes used in the deep past, too, and require tons of logic and
software support to pull off.
