Frequently Asked Questions

What is the difference between binary and decimal?
Binary uses 1024 as the multiplier (used by operating systems), while decimal uses 1000 (used by storage manufacturers).
What units are supported?
Bytes, Kilobytes (KB), Megabytes (MB), Gigabytes (GB), Terabytes (TB), and Petabytes (PB).
Why does my hard drive show less space than advertised?
Manufacturers use decimal (1000-based) units, while your OS uses binary (1024-based). A 1 TB drive is 1,000,000,000,000 bytes, which is about 931 GiB.
