What is A PetaByte?

According to

  • Wikipedia
    • “A petabyte (derived from the SI prefix peta- ) is a unit of information equal to one quadrillion (short scale) bytes, or 1 billiard (long scale) bytes. The unit symbol for the petabyte is PB. The prefix peta (P) indicates the fifth power to 1000”
  • www.WhatsAByte.com:
    • "A Petabyte is approximately 1,000 Terabytes or one million Gigabytes. It's hard to visualize what a Petabyte could hold. 1 Petabyte could hold approximately 20 million 4-door filing cabinets full of text. It could hold 500 billion pages of standard printed text. It would take about 500 million floppy disks to store the same amount of data."

To get a better feel for the size of a PetaByte check out this info graphic from mozy.com. Part of the infographic is shown here (it’s pretty large so you will need to visit their site to see the whole infographic)

These days, big data is a big trend. Large-scale organizations like Google, Twitter, and Facebook generate massive amounts of data daily (e.g. Google processes around 20 PetaBytes of data every day). But big data isn’t just about the volume of information that’s being generated and stored. Big data also entails how this information is organized, searched, shared, curated, analyzed, visualized, and so on; without some sort of filter, big data is cumbersome at best and useless at worst. Infragistics’ data visualization solutions, Ignite UI (HTML5/jQuery), NetAdvantage for WPF, and NetAdvantage for Silverlight help make sense of mountains of data so it becomes not just manageable but interactive, vibrant, and compelling.
