Humankind shared 65 exabytes of information in 2007, the equivalent of every person in the world sending out the contents of six newspapers every day.”
Researchers at the San Diego Supercomputer Center at the University of California, San Diego, estimate that, in 2008, the world’s 27 million business servers processed 9.57 zettabytes, or 9,570,000,000,000,000,000,000 bytes of information. This is “the digital equivalent of a 5.6-billion-mile-high stack of books from Earth to Neptune and back to Earth, repeated about 20 times a year.” The study also estimated that enterprise server workloads are doubling about every two years, “which means that by 2024 the world’s enterprise servers will annually process the digital equivalent of a stack of books extending more than 4.37 light-years to Alpha Centauri, our closest neighboring star system in the Milky Way Galaxy.” [more]
