Claim 0:
1. A data storage device, comprising:
a memory device, wherein the memory device is arranged into a first super device having a first plurality of active zones and a second super device having a second plurality of active zones; and
a controller coupled to the memory device, the controller configured to:
determine that both the first super device and the second super device comprise cold zones and hot zones, wherein:
a cold zone is a zone that has a number of resets less than a predetermined zone reset threshold; and
a hot zone is a zone that as a number of resets greater than the predetermined zone reset threshold; and

move cold zones from the second super device to the first super device, wherein:
moving the cold zones from the second super device to the first super device is responsive to determining that a critical threshold limit of the second super device has been reached or exceeded;
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.
