Frequently Asked Questions
What is the difference between GB and GiB?
A gigabyte (GB) uses the SI standard of 1,000 MB (1 billion bytes), while a gibibyte (GiB) uses the binary standard of 1,024 MiB (1,073,741,824 bytes). This is why a 500 GB drive shows about 465 GiB.
How many MB are in a GB?
There are 1,000 megabytes (MB) in one gigabyte (GB) using the SI decimal standard. Using binary units, there are 1,024 mebibytes (MiB) in one gibibyte (GiB).
How many GB is a TB?
One terabyte (TB) equals 1,000 gigabytes (GB) in decimal notation. In binary notation, one tebibyte (TiB) equals 1,024 gibibytes (GiB).
Why does my hard drive show less space than advertised?
Drive manufacturers use decimal units (1 GB = 1 billion bytes), while operating systems use binary units (1 GiB = 1,073,741,824 bytes). This difference makes drives appear about 7% smaller.
