Abstract: Monitoring write amplification metrics for a flash-based storage system, including: generating, by a controller of a storage system, data describing write activity for each storage device of a plurality of storage devices of the storage system, wherein the data describing the write activity comprises data describing application write activity for each storage device of the plurality of storage devices; calculating, by the controller of the storage system, for each storage device of the plurality of storage devices, a corresponding write amplification metric; and providing, by the controller of the storage system, to each storage device of the plurality of storage devices, the corresponding write amplification metric.
