In one embodiment, one or more storage arrays of solid state drives (SSDs) that include a plurality of segments are organized as one or more redundant array of independent disks (RAID) groups, where the RAID groups provides data redundancy for the segments. A node executing a layered file system of a storage input/output (I/O) stack performs segment cleaning to clean the segments. It further initiates rebuild of a RAID configuration of the SSDs on a segment-by-segment basis in response to the segment cleaning. In such a configuration, each segment includes one or more RAID stripes that provide a level of data redundancy as well as RAID organization for the segment.
