An exabyte (derived from the SI prefix exa-) is a unit of information or computer storage equal to one quintillion bytes. It is commonly abbreviated EB.

• 1,000,000,000,000,000,000 bytes — 1000⁶, or 10¹⁸, or
• 1,152,921,504,606,846,976 bytes — 1024⁶, or 2⁶⁰.

The term "exbibyte", using a binary prefix, has been proposed as an unambiguous reference to the latter value. An exbibyte (a contraction of exa binary byte) is a unit of information or computer storage, abbreviated EiB. 1 exbibyte = 260 bytes = 1,152,921,504,606,846,976 bytes = 1,024 pebibytes The exbibyte is closely related to the exabyte, which can either be a synonym for exbibyte, or... // In computing, binary prefixes can be used to quantify large numbers where powers of two are more useful than powers of ten (such as computer memory sizes). ...

As of 2007, exabytes of data are almost never encountered in any practical context, except to refer to the address space of 64-bit architectures as 16.0 exabytes.^[1] 2007 is a common year starting on Monday of the Gregorian calendar. ...

Popular expression

"All words ever spoken"

A popular expression claims that "all words ever spoken by human beings" could be represented by approximately 5 exabytes of data,^[2][3][4] often citing a project at the UC Berkeley School of Information in support.^[5] The 2003 University of California Berkeley report credits the estimate to the website of Caltech researcher Roy Williams, where the statement can be found as early as May, 1999.^[6] This statement has been criticized.^[7][8] Mark Liberman calculated the storage requirements for all human speech at 42 zettabytes, if digitized as 16 kHz 16-bit audio, although he did "freely confess that maybe the authors [of the exabyte estimate] were thinking about text".^[9] The UC Berkeley School of Information is a graduate school offering both a professional masters degree as well as a research-oriented PhD degree. ...

Earlier Berkeley studies estimated that by the end of 1999, the sum of human-produced information (including all audio, video recordings and text/books) was about 12 exabytes of data.^[10] The 2003 Berkeley report stated that in 2002 alone, "telephone calls worldwide on both landlines and mobile phones contained 17.3 exabytes of new information if stored in digital form", and "it would take 9.25 exabytes of storage to hold all U.S. [telephone] calls each year."^[5] International Data Corporation estimates that 161 exabytes of digital information were created, captured, and replicated worldwide in 2006.^[11]

Exaflood

The word exabyte is the basis for the term "exaflood", a neologism created by Bret Swanson of the Discovery Institute in a January 2007 Wall Street Journal editorial.^[12] Exaflood refers to the rapidly increasing torrent of data transmitted over the Internet. The amount of information people upload, download and share on the Internet is growing (due in large part to video, audio and photo applications), at an exponential rate while the capacity of the Internet, its bandwidth, is limited and susceptible to a “flood” of data. A neologism (Greek νεολογισμός [neologismos], from νέος [neos] new + λόγος [logos] word, speech, discourse + suffix -ισμός [-ismos] -ism) is a word, term, or phrase which has been recently created (coined) — often to apply to new concepts, to synthesize pre-existing concepts, or to make older terminology sound more contemporary. ...

In Fiction

• In the computer game Marathon by Bungie, the AI Durandal is "sixty-four billion exobytes" large, as seen on the last terminal screen of the level "Try Again."^[13] It is not clear if the misspelling of exabyte was intentional or rather a result of its incredible size and near non-use during 1995 when the game was written.
• In the movie Ocean's Thirteen, The Bank Hotel and Casino's advanced AI security system, the Greco, is said to process game winners' reactions "in a field of exabytes."
