Abstract: Each SSD in an array is divided into splits that are contiguous LBA ranges of equal capacity. The splits are managed as if they were sub-drives or logical drives and used in RAID groups or other forms of redundancy schemes. A processor external to the SSD collects pending defect data log from the SSDs and determines which splits are associated with reported defects. Failed splits are rebuilt in spare splits using RAID or another redundancy scheme. Repaired splits are returned to service as spare splits. Irreparable splits are marked as lost. In the case of SSD failure the data splits of the SSD are rebuilt to a spare SSD. If enough failed splits of the failed SSD can be repaired then the repaired SSD may be returned to service.
