Study: Humanity Can Store 295 Exabytes of Data

Friday Feb 11th 2011 by Staff

All of the manufactured storage available contains just one hundredth of the capacity of humanity's DNA.

Cnet: Researchers Martin Hilbert and Priscilla Lopez from the University of Southern California have published a new paper that attempts to add up all of the storage capacity in USB thumb drives, CDs, chip-enabled credit cards, videocassettes, library books, Babylonian clay tablets and other human inventions. They say the total is 295 exabytes. (An exabyte is 1,000 petabytes, which is 1,000 terabytes, which is 1,000 gigabytes.) And they say that number is growing at 58 percent per year.

Still, 295 exabytes is only about one hundredth of the storage capacity of humanity's DNA.
