Applying endurance groups to zoned namespaces

EGs may be combined with ZNSs to offer greater control of how, where and under what configurations, data is stored to various user-defined sections on a SSD. In embodiments, this exposure of control functionalities to an SSD host provides improved performance to data center and other hyperscale users and their clients. In embodiments, larger SSDs may be partitioned into groups of zones for better usage by host devices. In embodiments, the groups may comprise, for example, EGs, sets and MUs, each containing a defined number of zones. In one or more embodiments, hosts may use different EGs to access the device and thereby manage die or channel conflicts in the SSD.
