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).
