Systems, methods and/or devices are used to enable notification of a trigger condition to reduce declared capacity of a storage device in a multi-storage-device storage system. In one aspect, the method includes: (1) obtaining, for each storage device of a plurality of storage devices, one or more metrics of the storage device, the storage device including non-volatile memory, (2) detecting a trigger condition for reducing declared capacity of the non-volatile memory of a respective storage device of the plurality of storage devices, the trigger condition detected in accordance with the one or more metrics of two or more of the storage devices, and (3) notifying a host of the trigger condition for reducing declared capacity of the non-volatile memory of the respective storage device, the trigger condition for enabling performance of an amelioration process to reduce declared capacity of the non-volatile memory of the respective storage device.
