The SD Association (the people who brought us the popular SD flash memory card standards) at this year’s CES have announced a new memory card specification called SDXC, where the two letters behind SD stand for “eXtended Capacity”.
The specification is quite amazing, providing up to 2 terabytes storage capacity and accelerates SD interface read / write speeds of up to 104 megabytes per second, with a road map to 300 megabytes per second.
The SDXC specification, developed by the SD Association, leapfrogs memory card interface speeds while retaining the world-leading SD interface. Specifications for the open standard will be released in the first quarter of 2009. SDHC, Embedded SD and SDIO specifications will also benefit from the new SD interface speeds.
To put everything into perspective, a 2TB SDXC memory card will be able to store a whooping 100 HD movies, 60 hours of HD recording or 17,000 fine grade photos.
