An embodiment of an electronic apparatus may include 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, perform data access to a first physical cluster of the two or more physical clusters at a first bandwidth, and 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. Other embodiments are disclosed and claimed.
