Managing a solid state drive ('SSD') in a Redundant Array of Inexpensive Drives ('RAID'), including: detecting, by a RAID engine, a number of cell failures of the SSD exceeding a predetermined threshold; responsive to detecting the number of cell failures of the SSD exceeding the predetermined threshold: redirecting, by the RAID engine, a write of data not originally stored in the RAID to a drive in the RAID other than the SSD; and redirecting, by the RAID engine, writes originally directed to data stored on the SSD to another drive in the RAID, including unmapping the data stored on the SSD.
