Abstract
In non-limiting examples of the present disclosure, systems, methods and devices for partitioning dies based on spare blocks and workload expectations are provided. Data from non-volatile storage media may be received. The data may comprise information identifying each of a plurality of dies included in the non-volatile storage media and a number of blocks included in each of the plurality of dies. A number of spare blocks included in each of the plurality of dies may be determined. First and second sets of the plurality of dies may be identified, wherein the first set has a higher number of spare blocks than the second set. A first workload may be assigned to the first set of dies, the first workload being classified as write-intensive. A second workload may be assigned to the second set of dies, the second workload being classified as read-intensive.
