A zebibyte (a contraction of zetta binary byte) is a unit of information or computer storage, commonly abbreviated ZiB.

1 zebibyte = 2⁷⁰ bytes = 1,180,591,620,717,411,303,424 bytes = 1,024 exbibytes

The zebibyte is closely related to the zettabyte, which can either be a synonym for zebibyte, or refer to 10²¹ bytes = 1,000,000,000,000,000,000,000 bytes, depending on context (see binary prefix).

The zebi and yobi prefixes were originally not part of the system of binary prefixes, but were added by the International Electrotechnical Commission in August 2005.^[1]
