The specification, that should be complete Q1 subsequent year, will grasp 300MB per second by adding the second row of electrical contacts upon a bottom face of a card, and will be back concordant with comparison, slower devices. Although being referred to internally as SD 4.0, brand names for a technology are still being deliberate — with UHS-II (the successor to UHS-I ultra-high speed train cards) as one probability.
