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

Gibibyte (GiB): 1,073,741,824 bytes (2^30), the binary unit used for RAM and by some operating systems.
Megabyte (MB): 1,000,000 bytes in the decimal system, used by storage makers and file sizes.
