What is the ambiguous difference between 120G and 128G in ssd?

Computer

In the case of RAM, it is divided into 2G, 4G, and 8G exactly, and in the case of SSd, it is divided into 120G and 128G quite vaguely.

What's the difference in performance between 120G and 128G?

What's the pretty vague 8G difference?
