Perhaps it was a fascination with dinosaurs that led to one of the largest units of data volume being called the brontobyte. And just like the Brontosaurus, the brontobyte is also awe-inspiring; it seems gigantic and somehow unmanageable and inconceivable. The brontobyte comes after the gigabyte, terabyte, petabyte, exabyte, zettabyte and yottabyte.
One brontobyte equals around 10 to the 27th power of bytes, or a 1 followed by 27 zeros. This volume of data would be equivalent to the US (United States) Library of Congress 100 trillion times over; every person in the world would have 12,500 copies of this library. This is big data in the truest sense of the word.
