A Super Page is the optimal unit for physical read and write. It consists of the same hardware page from each die in the virtual device. When data is read or written, the super page construct allows the data to be striped across the dies to achieve the maximum performance by involving each die of the virtual device in parallel.
Unlike a regular page, the size of a super page is not static but is defined by the geometry of the virtual device. Super pages are read and written in integer multiples of ADUs. Super pages are grouped into super blocks. The number of super pages contained in a super block is a static number defined by the specific generation of flash memory die being used in the device.
