The SD Association, a global alliance of more than one thousand companies involved in the Secure Digital (SD) memory cards, has announced the new standard for this type of cards: SDXC. This new type, as an evolution of SDHC, will be able to have capacities up to.... 2 TB (2'000 GB!) and 300 MB/s of speed.
The new standard should be completed around March.
