Definition of exabyte [EB] unit

An exabyte (EB) is a unit of digital information equal to one quintillion bytes in the decimal system, or 1018 bytes. In binary usage, an exabyte may refer to 260 bytes, more precisely called an exbibyte (EiB).

History of exabyte [EB] unit

The prefix “exa-” was established by the International System of Units (SI) in 1991, extending the standardized decimal prefix series beyond peta-. It derives from the Greek word hex, meaning “six,” because exa represents 1018, or six groups of three zeroes. As digital technologies produced enormous datasets, the exabyte became a practical storage term during the late twentieth and early twenty-first centuries. The International Electrotechnical Commission later introduced “exbibyte” for the binary quantity 260 bytes, helping distinguish decimal and binary measurements.
