Abstract
A method for flash sparing on a solid state drive (SSD) includes detecting a failure from a primary memory device; determining if a failure threshold for the primary memory device has been reached; and, in the event the failure threshold for the primary memory device has been reached: quiescing the SSD; and updating an entry in a sparing map table to replace the primary memory device with a spare memory device.
