Abstract

One or more source locations in a group of solid state storage cells on which garbage collection is to be performed are stored in a garbage collection queue. A garbage collection speed is determined, including by: analyzing one or more source locations stored in the garbage collection queue; determining a look-ahead metric, wherein the look-ahead metric comprises an anticipated amount of freed up storage associated with the analyzed source locations; and determining the garbage collection speed based at least in part on the look-ahead metric. One or more garbage collection operations are performed interleaved with one or more host operations, wherein the ratio of garbage collection operations to host operations is based at least in part on the garbage collection speed.
