The SD Association has announced the next generation removable memory storage. The new card will have up to 2 terrabytes storage capacity making it possible to store 100 HD movies or 130k photos
The next-generation SDXC (eXtended Capacity) memory card specification, announced today at the 2009 International CES, dramatically improves consumers' digital lifestyles by providing the portable storage and speed needed to store weeks of high-definition video, years of photo collections and months of music to mobile phones, cameras and camcorders, and
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.
"SDXC combines a higher capacity roadmap with faster transfer speeds as a means to exploit NAND flash memory technology as a compelling choice for portable memory storage and interoperability," said Joseph Unsworth, research director, NAND Flash
Turning mobile phones into media centers
"With SDXC, consumers can quickly download higher quality content to their phones, including games, video and music – giving consumers a richer media and content experience," said James Taylor, president of the SD Association. "The SD interface already has proven itself valuable in mobile phones. Now, SDXC memory card capabilities will spur further handset sophistication and boost consumer content demand."
Shooting pictures at the speed of life
The first SDXC cards manufactured are likely to provide 64GB storage, doubling the 32GB maximum in SDHC memory cards. Even at early capacity levels, the SDXC card will improve user experience in products like cameras and camcorders.
"SDXC is a large-capacity card that can store more than 4,000 RAW images, which is the uncompressed mode professionals use. That capacity, combined with the exFAT file system, increases movie recording time and reduces starting time to improve photocapturing opportunities," said Shigeto Kanda, general manager at Canon.
SDXC will enable camcorders to provide longer, professional level HD video recording with a small form factor.
The SDXC specification uses Microsoft's exFAT file system to support its large capacity and interoperability in a broad range of PCs, consumer electronics and mobile phones. The exFAT system was designed for increased compatibility with flash media, from portability of data to interoperability with multiple platforms and devices on removable media.
"The SD Association is committed to answering and anticipating consumer demand for easy-to-use memory card storage that is interoperable in any device with a matching SD slot," Taylor said. "The SDXC card gives consumers a new, yet familiar, highperformance card that will be used in hundreds of manufacturers' device offerings."
