Frequently asked questions
- Does this use 1,000 or 1,024 as the multiplier between units?
- 1,024 (the binary convention — 1 KB = 1,024 bytes), matching how operating systems like Windows and macOS report file and drive sizes. This differs from the strict SI decimal definition (1,000) that some storage manufacturers use on packaging, which is part of why a "1 TB" drive shows less than 1 TB free space in your OS.
