GB vs GiB: why your storage looks smaller than advertised
· CloudWink team
You buy a 1 TB drive and your computer says 931 GB. Nothing is missing. Two units share almost the same name.
Two ways to count.
A GiB is about 7 percent bigger than a GB, and the gap grows at terabyte scale.
- 1 GB (gigabyte) = 1,000,000,000 bytes. Decimal, used by drive makers and most storage plans.
- 1 GiB (gibibyte) = 1,073,741,824 bytes, which is 1024 × 1024 × 1024. Binary, used by many operating systems.
- 1 TiB is about 1.1 TB, and 1 TB is about 0.91 TiB.
Why it matters when comparing plans.
A plan quoted in GiB gives you slightly more space than the same number in GB. 100 GiB is about 107 GB. 1 TiB is about 1,100 GB.
CloudWink uses binary units.
CloudWink quotas are stated in GiB and TiB: 10 GiB, 100 GiB, 400 GiB and 1 TiB. That is the space you get, measured the same way the app reports it.
