About these units
Terabyte (TB)
A terabyte equals 1,099,511,627,776 bytes (2⁴⁰) in binary or 1 trillion bytes in decimal. Terabytes are associated with large-scale data storage: cloud drives, archival systems, scientific datasets, game installations, and high-definition video libraries. Modern personal computers often include terabyte-level drives, and enterprise systems may contain thousands of terabytes. The TB marks the boundary where storage becomes "big data," enabling machine learning training sets, genomic databases, and detailed satellite imagery archives. At this scale, efficient data management, compression, and redundancy become critical challenges.
Gigabyte (10^9 bytes) (GB (10^9))
A decimal gigabyte is 1,000,000,000 bytes and is the standard unit for hard drive and SSD capacities. As storage technology scaled into the hundreds of gigabytes and then terabytes, the decimal definition became more practical, allowing consistent scaling across consumer and enterprise devices. However, operating systems often report capacities using binary units, causing user confusion (e.g., a "500 GB" drive showing only ~465 "GB"). This mismatch persists despite standardization efforts.
