1,073,741,824
1,073,741,824 is 2³⁰, the number of bytes in a gibibyte.
Where 1,073,741,824 fits
Why 1,073,741,824 is special
This is the number behind the mismatch between what a drive says and what a computer reports. A manufacturer's gigabyte is 1,000,000,000 bytes; an operating system reporting in gibibytes divides by this instead, which makes a 1 TB drive show as about 931 GB with nothing missing.
