A solid-state data storage system that does not have a convective cooling capability can arrange a plurality of memory cells into a plurality of logical namespaces with each logical namespace sequentially written, and entirely erased, as a single unit. The logging of data access activity to the plurality of memory cells with a heat module may determine a workload to at least one namespace. The heat module can create an active heat strategy in view of the at least one namespace workload before an active data access operational policy for a first namespace is altered in response to detection of a workload trigger.
