Abstract:
Systems, methods and/or devices are used to enable a settings adjustment mechanism. In one aspect, the method includes (1) accessing characterization information corresponding to how a group of non-volatile memory devices of a storage control system operates as the group wears, (2) determining an estimated age of a non-volatile memory device, of the group of non-volatile memory devices, in accordance with a wear indicator for the non-volatile memory device, and (3) determining one or more settings for the non-volatile memory device in accordance with the estimated age and the characterization information.
