– at full speed; real transfers are usually 10–20% slower

Why does a 500 GB drive show as 465 GB? Drive makers count 1 GB as 1,000,000,000 bytes; Windows divides by 1,073,741,824 (a GiB) but still writes "GB". macOS, iOS and Android use decimal units.

Decimal or binary?

  • Decimal units (kB, MB, GB) count in thousands: 1 GB = 1,000,000,000 bytes. Disk makers, macOS, phones and most websites use them.
  • Binary units (KiB, MiB, GiB) count in 1,024s: 1 GiB = 1,073,741,824 bytes. Windows and memory sizes use them, though Windows writes "GB".
  • Network speeds are in bits: 100 Mbit/s moves 12.5 MB per second.
