January 8, 2009: The SD Association has announced the next generation SDXC (Secure Digital eXtended Capacity) memory card specification, which supports up to 2TB storage capacity and increases SD interface read/write speeds to 104MB per second.
Specifications for the open standard will be released in the first quarter of 2009. The SDXC specification uses Microsoft’s exFAT file system to support its large capacity and interoperability in a range of PCs, consumer electronics, and mobile phones. Plans are for data transfer speeds up to 300MB/second to be offered in the future. The Association claims maximum transfer speeds will be maintained right up to the maximum 2TB storage capacity.
This feature will enable the development of mobile phones with expanded entertainment and data storage capabilities as well as camcorders that provide longer, professional level HD video recording with a small form factor. A 2TB SDXC memory card will be able to store 100 HD movies, 60 hours of HD recording, more than 4000 raw image files or 17,000 fine-grade photos. SDHC, Embedded SD and SDIO specifications will also benefit from the new SD interface speeds. The first products are expected to be released this year.
