As the world continues its digital revolution, the data requirements have grown exponentially. A recent study of Fortune 1000 companies reveal that IT administrators have seen data storage needs grow to more than a petabyte (1,000,000 gigabytes) in the past three years. "Lesser" Fortune 10000 companies typically need up to 100 terabytes of storage. Such data requirements represent a five-fold and two-fold increase respectively. Outside of business, analysts have determined the total storage requirement for the world’s data in 2006 touched on 161 exabytes, up significantly from the 5 exabytes of data in 2003. The complete study, "The Expanding Digital Universe (PDF)," by the IDC is available on-line.
