The memory device is arranged into at least a first super device and a second super device, each of the super devices having a plurality of active zones. The controller is configured to determine that each of the super devices includes both cold zones and hot zones, where a cold zone is a zone that is overwritten less than a hot zone. The controller is further configured to move cold zones from one super device to another super device upon determining that the another super device is below a threshold limit, where the threshold limit is a minimum free space to be maintained in a super device. The controller is further configured to move cold zones between super devices, such that the cold zones are concentrated in at least one super device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Purposeful super device imbalance for ZNS SSD efficiency","description":"A data storage device includes a memory device and a controller coupled to the memory device.
