About these units
Gigabytes (GB): A gigabyte (GB) is 1,000,000,000 bytes in the decimal (SI) system used by drive makers and network providers.
Gibibytes (GiB): A gibibyte (GiB) is 2³⁰ = 1,073,741,824 bytes. Windows reports storage in this binary unit but labels it “GB”, which is why a 1 TB drive shows about 931 GB.
