1. An electronic apparatus, comprising:
a substrate; and
a controller coupled to the substrate, the controller including circuitry to:
control access to a NAND-based storage media that includes a plurality of NAND devices located on the substrate and organized into two or more physical clusters with each NAND device uniquely assigned to one of the two or more physical clusters, wherein the two or more physical clusters are arranged around the controller with a fastest physical cluster of the two or more physical clusters being closest to the controller, NAND devices of the fastest physical cluster comprising NAND devices with a lowest number of levels of the plurality of NAND devices;
perform data access to a first physical cluster of the two or more physical clusters at a first bandwidth;
perform data access to a second physical cluster of the two or more physical clusters at a second bandwidth that is slower than the first bandwidth;
present the two or more physical clusters to a host operating system each as a different respective virtual drive; and
direct an access request to a particular one of the two or more physical clusters based on a drive target of an input/output transaction.
