Exabyte

An exabyte is 1018 or 1,000,000,000,000,000,000 bytes.

One exabyte (abbreviated "EB") is equal to 1,000 petabytes and precedes the zettabyte unit of measurement. Exabytes are slightly smaller than exbibytes, which contain 1,152,921,504,606,846,976 (260) bytes.

The exabyte unit of measure measurement is so large, it is not used to measure the capacity of data storage devices. Even the storage capacity of the largest cloud storage centers is measured in petabytes, which is a fraction of one exabyte. Instead, exabytes are used to measure the sum of multiple storage networks or the amount of data transferred over the Internet in a certain amount of time. For example, several hundred exabytes of data are transferred over the Internet each year.
