A petabyte (derived from the SI prefix peta- ) is a unit of information equal to one quadrillion (short scale) bytes, or 1000 terabytes. It is abbreviated PB. The prefix peta- (P) indicates a power of 1000:
- 1 PB = 1,000,000,000,000,000 B = 10005 B = 1015 B.
However, historically, the term petabyte may have been used confusingly to designate 10245 bytes (which is actually a "pebibyte").
[edit] Petabytes in use
Examples of the use of "petabyte" to describe data sizes in different fields are:
- Telecoms: AT&T has about 19 petabytes of data transferred through their networks each day.[4]
- Physics: The 4 experiments in the Large Hadron Collider will produce about 15 petabytes of data per year, which will be distributed over the LHC Computing Grid.[5]
- P2P networks: As of October 2009, Isohunt has about 9.76 petabytes of files contained in torrents indexed globally.[6]
- Archives: The Internet Archive contains about 3 petabytes of data, and is growing at the rate of about 100 terabytes per month as of March, 2009.[7][8]
- Games: World of Warcraft utilizes 1.3 petabytes of storage to maintain its game.[9] Valve Steam delivers 20 petabytes of content monthly. [10]
- Film: The 2009 movie Avatar is reported to have taken over 1 petabyte of local storage at Weta Digital for the rendering of the 3D CGI effects.[11][12]
