Bar length represents bytes. The physical sizes of devices are schematic; encoding and compression affect file sizes.
A little perspective
1 terabyte and 1 TB drive have approximately the same data.

1 terabyte
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.
1 TB drive
One trillion advertised bytes: approximately 931 GiB. This is not a loss of physical storage.
Defined examples — our methodology
The marked data is calibrated. Unmeasured illustration details are representative.

Why these numbers?
The visual compares data with data. The records below preserve each value’s basis and caveats.

- Comparing
- Data ↔ Data
- Relative size
- The two selected measurements are approximately equal.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- 1 TB drive is labelled example; treat the displayed value as a comparison anchor rather than false precision.
