A petabyte (derived from the SI prefix peta- ) is a unit of information equal to one quadrillion (short scale) bytes, or 1000 terabytes. The unit symbol for the petabyte is PB. The prefix peta- (P) indicates a power of 1000:
- 1 PB = 1,000,000,000,000,000 B = 100012 B = 1015 B.
The term "pebibyte" (PiB), using a binary prefix, is used for the corresponding power of 1024.
Petabytes in use
Examples of the use of "petabyte" to describe data sizes in different fields are:
- Computer hardware: Teradata Database 12 has a capacity of 50 petabytes of compressed data.[1][2]
- Internet: Google processes about 24 petabytes of data per day.[3]
- 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]
- Climate Science: The German Climate Computing Center (DKRZ) has a storage capacity of 60 petabytes of climate data.[6]
- P2P networks: As of June 2010, Isohunt has about 10.8 petabytes of files contained in torrents indexed globally.[7]
- 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.[8][9]
- Games: World of Warcraft utilizes 1.3 petabytes of storage to maintain its game.[10] Valve Steam delivers 20 petabytes of content monthly.[11]
- 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.[12][13]

Of course there's no such thing as a petabyte iPod, but the good news is that we may not have too long to wait for one. Hitachi Data Systems already sells a product called the TagmaStore Universal Storage Platform which can manage up to 32 petabytes of storage for the very largest corporations, so you'd have to conclude that a pocket-sized consumer version isn't out of the question in a decade or so.
