Each individual solid state drive is operated in either an Active Mode in which I/O commands are processed or in a Maintenance Mode in which garbage collection is performed and no I/O commands are processed. The selection of solid state drives in the Active Mode is further selected to achieve wear leveling over the pool of solid state drives.
