Today's zetabyte story, excerpted from the UC San Diego press release:
The world’s roughly 27 million computer servers processed 9.57 zettabytes of information in 2008, according to a paper to be presented April 7 at Storage Networking World’s (SNW’s) annual meeting in Santa Clara, Calif. The first-of-its kind rigorous estimate was generated with server-processing performance standards, server-industry reports, interviews with information technology experts, sales figures from server manufacturers and other sources. (One zettabyte is 10 to the 21st power, or a million million gigabytes.)How much info is this? According to the press release, it's "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."
I wonder what kind of books...maybe the hard-copy encyclopedias that we don't look at any more.
Check out Gary Robbins' story on the topic in the San Diego Union Tribune: "Business data could fill books reaching to Neptune and back."
