The world produces between one and two exabytes of unique information per year, which is roughly 250 megabytes for every man, woman, and child on earth. An exabyte is a billion gigabytes, or 1018 bytes. Printed documents of all kinds comprise only .003% of the total. Magnetic storage is by far the largest medium for storing information and is the most rapidly growing with shipped hard drive capacity doubling every year. Magnetic storage is rapidly becoming the universal medium for information storage.
