Drive storage discrepancy explained: Decimal vs. Binary calculations

By PulseAugur Editorial · [1 sources] ·

Storage manufacturers often market drive capacity using a base-10 (decimal) system, where 1GB equals 1 billion bytes. However, operating systems like Microsoft Windows typically calculate storage in a base-2 (binary) system, where 1GB equals 1,073,741,824 bytes. This difference in calculation leads to a discrepancy, making a 1TB drive appear as only 931GB in Windows, even though no data is lost. Additionally, a portion of the advertised storage is often reserved for the pre-installed operating system and essential software, further reducing usable space. AI

IMPACT Understanding storage calculations is crucial for managing large AI datasets and model files.
