Abstract
A storage system determines a present amount of reclaimable space in storage memory. The storage system determines a garbage collection directive based on the present amount of reclaimable space in comparison to a target amount of reclaimable space. The storage system selects blocks of storage memory for a group of blocks for garbage collection. Each block selected has greater than or equal to a threshold amount of reclaimable space in accordance with the garbage collection directive. The storage system performs garbage collection, using blocks from the group.
