The SD Card Association has a new spec in the works of concept that will most likely triple the speed of its SDHC and SDXC cards, as they hope. The specification, which should be complete in Q1 next year, will achieve 300MB per second by adding a second row of electrical contacts on the bottom face of the card, and will be backward compatible with older, slower devices. Although being referred to internally as SD 4.0, brand names for the technology are still being considered — with UHS-II (the successor to UHS-I ultra-high speed bus cards) as one possibility. How this turn out to be backward compatible, is really sceptical. But since they said ‘ye’, I guess it’s really ‘ye’. Fast and furious cards coming! Make way please!
