Classification: CPC G | IPC G

Claim 19:
20. A data storage system, comprising:
a data storage device including:
a volatile memory; and
a plurality of non-volatile memory devices;

means for setting, responsive to determining to decompose and recompose the data storage device, a flag indicating that flushing a virtual-to-physical (V2P) mapping table of the data storage device is unnecessary for a next reset command;
means for downloading a firmware update to the data storage device;
means for activating the firmware update in the data storage device;
means for receiving the next reset command at the data storage device, wherein reset commands normally include a step to flush the V2P mapping table from the volatile memory to at least one non-volatile memory device of the plurality of non-volatile memory devices in the data storage device;
means for determining, prior to executing flushing of the V2P mapping table for the next reset command, whether the flag is set;
means for forgoing, responsive to determining that the flag is set and executing the next reset command, the step of flushing the V2P mapping table; and
means for completing the reset command without flushing the V2P mapping table, wherein:
the V2P mapping table is cleared from the volatile memory by a power cycle of the reset command; and
a provisioning time of decomposing and recomposing the data storage device is reduced.
