Abstract

See full text

A method includes identifying a product warranty for each of a plurality of flash memory devices within a system, wherein the product warranty includes a maximum number of writes and a maximum age, and tracking the number of writes made to each flash memory device and the age of each flash memory device. The method further includes determining, for each flash memory device, a number of pro rata writes remaining in the product warranty, which is determined as a number of writes remaining until the flash memory device reaches the maximum number of writes identified in the product warranty divided by an amount of time remaining until the flash memory reaches the maximum age identified in the product warranty. The method then causes data to be written to the flash memory device having the greatest number of pro rata writes remaining in the product warranty.
