During the next eight years, the amount of digital data produced will exceed 40 zettabytes, which is the equivalent of 5,200 GB of data for every man, woman and child on Earth, according to an updated Digital Universe study released today.
To put it in perspective, 40 zettabytes is 40 trillion gigabytes -- estimated to be 57 times the amount of all the grains of sand on all the beaches on earth. To hit that figure, all data is expected to double every two years through 2020.
