The SD Card Association (truth be told, one of our favorite card-related associations) has a new spec in the works that will almost triple the speed of its SDHC and SDXC cards, according to CNET. The specification, which should be complete 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.
