Data is distributed to solid-state disks (SSDs) using the RAID-0 technique. Based on a utilization of a first region of a first one of the SSDs, the first region is selected for garbage collection. Valid data from the first region is copied to an active region of the first one of the SSDs as part of a process of garbage collection. While the process of garbage collection is being performed, data is distributed to a subset of the SSDs using the RAID-0 technique where the subset of the SSDs does not include the first one of the plurality of nonvolatile solid-state memories selected for garbage collection.
