Five exabytes. How much data is that? In nearly two decades of working in the computer industry, I had never paid much attention to a unit of measurement larger than a terabyte. Well, according to Eric Schmidt, Google CEO, five exabytes of data is approximately the sum total of all the information produced by humankind from the dawn of time through the year 2003.
Five exabytes also happens to be the approximate amount of information that the human race now generates every two days. Twitter alone produces the equivalent of Tolstoy’s War and Peace every two minutes.
