What is the Difference Between Terabyte and Tebibyte

Aspect	Terabyte (TB)	Tebibyte (TiB)
Definition	A unit of digital information storage based on the decimal system (base 10).	A unit of digital information storage based on the binary system (base 2).
Measurement System	Decimal (SI – International System of Units)	Binary (IEC – International Electrotechnical Commission)
Value in Bytes	1 TB = 1,000,000,000,000 bytes (10^12 bytes)	1 TiB = 1,099,511,627,776 bytes (2^40 bytes)
Comparison	1 TB < 1 TiB	1 TiB > 1 TB
Usage	Commonly used by hard drive manufacturers and for general storage capacity.	Used in computing and data processing to accurately represent binary multiples.
Practical Example	A 2 TB hard drive offers about 1.82 TiB of storage space.	A file size of 1 TiB is larger than 1 TB file size.
Prefixes and Symbols	Uses the SI prefix “tera-” (T)	Uses the IEC prefix “tebi-” (Ti)
