Abstract
A nonvolatile storage system including several data storage arrays; a counter storage array for storing values indicating the remaining useful life of each of the data storage arrays; and a device for controlling access to each of the data storage arrays as a function of the values stored in each counter array. The counter array has an appreciably longer useful life than any of the data storage arrays.
