Claim 14:
15. A data storage device, comprising:
memory means for storing data, wherein the memory means is arranged into a plurality of super devices each having a plurality of active zones; and
a controller coupled to the memory means, wherein the controller configured to move the data between super devices to ensure more cold zones are concentrated in a first super device of the plurality of super devices, wherein:
a cold zone is a zone that has a number of resets less than a predetermined zone reset threshold;
a hot zone is a zone that has a number of resets greater than the predetermined zone reset threshold;
moving the data between super devices is responsive to a super device of the plurality of super devices reaching or exceeding a critical threshold limit;
the critical threshold limit is a minimum free space to be maintained within a super device; and
the cold zones are consolidated to a super device designated for cold zones.
