Because of irregularities in the definition and usage of terms for byte multiples, the exact number can be either one of the following:

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

Because of these irregularities, the term "exbibyte" has been proposed as an unambiguous reference to the latter value. (See binary prefixes.) 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. ...

As of 2006, exabytes of data are almost never encountered in any practical context. For example, the total amount of printed material in the world is estimated to be around five exabytes. However, one may hear of 16 or 18 exabytes of address space when discussing 64-bit architectures. 2006 is a common year starting on Sunday of the Gregorian calendar. ... The introduction to this article provides insufficient context for those unfamiliar with the subject matter. ... In computing, a 64-bit component is one in which data are processed or stored in 64-bit units (words). ...

It was estimated that by the end of 1999, the sum of human-produced media (including all audio, video recordings and text/books) was about 12 exabytes.^[1]

Research at the UC Berkeley School of Information suggests that 5 exabytes of storage space was created in 2002 alone, 92% of it on magnetic media, mostly on hard disks.^[2] However, the vast majority of this space is used to store redundant intellectual works such as music and commercial video. The UC Berkeley School of Information is a graduate school offering both a professional masters degree as well as a research-oriented PhD degree. ...

It is claimed that 5 exabytes of data approximately equals "all words ever spoken by human beings."^[2][3][4] The 2003 University of California Berkeley report, often cited as the source of this statement, itself cites the website of Caltech researcher Roy Williams where the statement can be found as early as May, 1999.^[5] The validity of this estimate is disputed.^[6][7] California Institute of Technology The California Institute of Technology (commonly known as Caltech) is a private, coeducational university located in Pasadena, California, in the United States. ...

Since the data count of human vocals is several exabytes,^{[citation needed]} some people measure that by merging average values, which can have some inaccuracy; thus some would argue that all words spoken by humans would be closer to 1 yottabyte.^{[citation needed]} A yottabyte (derived from the SI prefix yotta-) is a unit of information or computer storage equal to one septillion (one long scale quadrillion or 1024) bytes. ...
