Terabytes (Tb) meaning

Terabytes (commonly abbreviated tb, sometimes seen as Tb) describe the size of electronic data typically handled in disclosure/eDisclosure, eDiscovery, DSARs, digital forensics and information governance. The term is not defined in legislation or case law; it is a descriptive technical unit used consistently across England & Wales, Scotland, Northern Ireland and Ireland. 1 TB equals 1,024 Gigabytes under the binary convention frequently used in litigation support. Some vendors and storage manufacturers use the decimal convention, where 1 TB equals 1,000 Gigabytes. Disclosure protocols, court orders, statements of work and costs budgets should specify which convention applies to avoid disputes over data volumes, processing thresholds, hosting charges and transfer limits. Note that TB refers to terabytes (bytes). In IT, Tb (lower-case b) can denote terabits (network capacity). Confirm the intended unit in instructions and contracts. Terabyte counts are used to scope preservation, collection and review, assess proportionality, estimate disclosure timelines and costs, and plan data protection compliance for large datasets and backups.
