Back in 2010, Google executive chairman Eric Schmidt forewarned of an impending data explosion. “Between the birth of the world and 2003, there were five exabytes of information created. We [now] create five exabytes every two days,” he said.
Last year, about 2.5 exabytes of data were being created daily, an amount that is expected to double roughly every three years. If you are unclear as to how large an exabtye is, it looks like this: 1,000,000,000,000,000,000. According to the Harvard Business Review, that is the equivalent of about 20 million filing cabinets’ worth of text.
