Orders of magnitude of data

A petabyte is 10 bytes of digital information. The unit symbol for the petabyte is PB.

The name is composed of the SI prefix peta- (P) composed with the non-SI unit of a byte.

1 PB = 1000000000000000B = 10bytes = 1000terabytes
1000 PB = 1 exabyte (EB)

A related unit, the pebibyte (PiB), using a binary prefix, is equal to 1024 bytes, which is more than 12% greater (2 bytes = 1125899906842624bytes).

Usage examples

Examples of petabyte storage sizes.

Examples of the use of the petabyte to describe data sizes in different fields are:

  • Telecommunications (capacity): The world's effective capacity to exchange information through two-way telecommunication networks was 281 petabytes of information in 1986, 471 petabytes in 1993, 2,200 petabytes in 2000, and 65,000 petabytes in 2007 (this is the informational equivalent to every person exchanging 6 newspapers per day).
  • Telecommunications (usage): In 2008, AT&T transferred about 30 petabytes of data through its networks each day. That number grew to 197 petabytes daily by March 2018.
  • Internet: Google processed about 24 petabytes of data per day in 2009. The BBC's iPlayer is reported to have transferred up to 7 petabytes each month in 2010. In 2012, Imgur transferred about 4 petabytes of data per month.
  • Supercomputers: In January 2012, Cray began construction of the Blue Waters, which has "up to 500 petabytes of tape storage".
  • Data storage system: In August 2011, IBM was reported to have built the largest storage array ever, with a capacity of 120 petabytes.
  • Digital archives: The Internet Archive surpassed 15 petabytes, as of May 2014.
  • Email: In May 2013, Microsoft announces that as part of their migration of Hotmail accounts to the new Outlook.com email service, they migrated over 150 petabytes of user data in six weeks.
  • File sharing (centralized): At its 2012 closure of file storage services, Megaupload held ~28 petabytes of user uploaded data.
  • File sharing (peer-to-peer): 2013 - BitTorrent Sync has transferred over 30 petabytes of data since its pre-alpha release in January 2013.
  • National Library: The American Memory digital archive of public domain resources hosted by the United States Library of Congress contained 15 million digital objects in 2016, comprising over 7 petabytes of digital data.
  • Film: The 2009 film Avatar is reported to have taken over 1 petabyte of local storage at Weta Digital for the rendering of the 3D CGI effects.
  • Video streaming: As of May 2013, Netflix had 3.14 petabytes of video "master copies", which it compresses and converts into 100 different formats for streaming.
  • Photos: As of January 2013, Facebook users had uploaded over 240 billion photos, with 350 million new photos every day. For each uploaded photo, Facebook generates and stores four images of different sizes, which translated to a total of 960 billion images and an estimated 357 petabytes of storage.
  • Music: One petabyte of average MP3-encoded songs (for mobile, roughly one megabyte per minute), would require 2000 years to play.
  • Steam, a digital distribution service, delivers over 16 petabytes of content to American users weekly.
  • Physics: The experiments in the Large Hadron Collider produce about 15 petabytes of data per year, which are distributed over the Worldwide LHC Computing Grid. In July 2012 it was revealed that CERN amassed about 200 petabytes of data from the more than 800 trillion collisions looking for the Higgs boson. The Large Hadron Collider is also able to produce 1 petabyte of data per second, but most of it is filtered out.
  • Neurology: It is estimated that the human brain's ability to store memories is equivalent to about 2.5 petabytes of binary data.
  • Climate science: The German Climate Computing Centre (DKRZ) has a storage capacity of 60 petabytes of climate data.
  • Sports: If you lined up a petabyte of data on 1gb flash drives that were an inch long and stretched them end to end, they would stretch over 92 football fields.
  • Entertainment: Based off 1 terabyte being 1024GB and the average 4k movie being 100GB, 1 petabyte of storage could hold 11,000 4k movies and take 2.5 years of nonstop viewing to watch.
