New Generation SD Memory Card Spec Supports 2TB Capacities

January 9, 2009

(ChattahBox) — The SD Association has announced in a press release at the 2009 International CES, a new card spec dubbed SDXC (eXtended Capacity) that can support memory capacities up to 2TB with read/write speeds to 104MB per second, with a road map to 300 megabytes per second.

According to their calculations, that would mean you could store 100 high-def movies, 60 hours of HD recording, or 17,000 fine-mode photos on a portable device. While this is spec at this point we could see something based on it as early as next year. While there aren’t many devices out there that could make full use of this kind of capacity and bus speeds right now, it could pull the industry forward more rapidly.

Here are a few quotes from the press release and more information on the SD Association:

“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 Semiconductors, at Gartner. “With industry support, SDXC presents manufacturers with the opportunity to kindle consumer demand for more advanced handset features and functionality in consumer electronics behind the ubiquitous SD interface.”

“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.”

“SDXC is a large-capacity card that can store more than 4,000 RAW images, which is the uncompressed mode professionals use, and 17,000 of the fine-mode most consumers use. That capacity, combined with the exFAT file system, increases movie recording time and reduces starting time to improve photo-capturing opportunities,” said Shigeto Kanda, general manager at Canon. “Improvements in interface speed allow further increases in continuous shooting speed and higher resolution movie recordings. As a memory card well suited to small-sized user-friendly digital cameras, the SDXC specification will help consumers realize the full potential of our cameras.”

SD Association
The SD Association is a global ecosystem of more than 1,100 technology companies charged with setting interoperable SD standards. The association encourages the development of consumer electronic, wireless communication, digital imaging and networking products that utilize market-leading SD technology. The SD standard is the number one choice for consumers and has earned nearly 80 percent of the memory card market with its reliable interoperability and its easy-to-use format. Today, mobile phones, Blu-ray players, HDTVs, audio players, automotive multimedia systems, handheld PCs, cameras and camcorders feature SD interoperability.
