Sir Isaac Newton's first law--the law of inertia--is as applicable to the world of data management as it is to our planet. Experts estimate that 60% to 80% (or more) of organizational data is never accessed after it's created; files often remain at rest, untouched and unmoved from companies' most expensive storage arrays.
