A method for managing overprovisioning in a solid state storage drive (SSD) array comprising (i) receiving usage data from each of a plurality of SSDs, (ii) determining a predicted service life value for each of the plurality of SSDs based on at least the usage data, (iii) comparing each of the predicted service life values with a predetermined service life value for each respective SSD, (iv) remapping at least one namespace in at least one of the plurality of SSDs among the plurality of SSDs, or reducing an available logical storage capacity for at least one of the plurality of SSDs. Here the remapping or reducing is based on a result of the comparing that the predicted service life value for the at least one of the plurality of SSDs is not greater than the predetermined service life value for that SSD.
