Decimal vs binary: KB, MB and GB use powers of 1,000 (SI), while KiB, MiB and GiB use powers of 1,024. Storage makers use decimal units; many operating systems and memory sizes use binary ones, which is why a "500 GB" drive shows less space.

About the units

Petabyte (PB): 10^15 bytes in the decimal system, used in data centres and big data.
Terabyte (TB): 10^12 bytes in the decimal system, used for hard drives and SSDs.
