Frequently asked questions
What is the difference between GB and GiB?
A GB is 1,000,000,000 bytes, a GiB is 1,073,741,824 bytes (1024 cubed). Operating systems often show GiB but label it GB.
Why does my 1 TB drive show less space?
Makers count 1 TB as 1,000,000,000,000 bytes, while many operating systems count in binary units. The system shows a smaller number, so nothing is missing.
When should I use KiB, MiB and GiB?
Use them when you mean the binary sizes of 1024. They remove doubt, as KB, MB and GB are used loosely for both decimal and binary values.
