Abstract: A data storage system may connect a non-volatile memory to a quarantine module that generates a quarantine strategy in response to a pending data access request to the non-volatile memory. The quarantine strategy can proactively prescribing a plurality of status levels for physical data addresses of the non-volatile memory. A comparison of a volume of errors for the non-volatile memory to a first threshold of the quarantine strategy with the quarantine module may prompt the alteration of a first status level of the plurality of status levels for a first physical data address of the non-volatile memory, as directed by the quarantine strategy.
