A little perspective

128 GB phone has about 2 times the data of 64 gigabytes.

Measurements, assumptions & sources +

64 gigabytes

Decimal kB, MB and GB use powers of 1,000. KiB, MiB and GiB use powers of 1,024. The content of a file depends on encoding and compression.

NIST — SI conversion factors

128 GB phone

128 billion advertised bytes. Operating-system and formatting space are not deducted.

Defined examples — our methodology

The marked data is calibrated. Unmeasured illustration details are representative.
