The SD Association has announced a new design that will allow an increase in bus interface speeds for SD-format memory cards up to 300MB/s. The new design is also backwards compatible with existing devices that accept SD, SDHC and SDXC cards. To give you an idea of what this transfer speed means in real products, SanDisk’s powerful Extreme Pro line of CF cards is rated at 90MB/s.

BERLIN, Sept. 2 /PRNewswire/ — IFA Hall 17, Booth 128 — The SD Association announced today it has defined a new, dual-row pin memory card design achieving bus interface speeds of up to 300 megabytes per second for SDXC and SDHC devices and memory cards. It is fully backwards compatible, allowing equipped devices full use of any SD, SDHC and SDXC memory cards.
New high speed interface signals will be assigned on the second row of pins of select SDXC and SDHC memory cards offering the new speed. This option will be available in both full-size and micro form factors and does not change the physical size or shape of the cards. This design will be part of the forthcoming SD 4.0 specification, expected in early 2011.
“Our innovative dual-row pin design ultimately lets consumers using equipped products to manage the massive storage capacity found on SDXC memory cards at incredible speeds,” said Norm Frentz, chairman of the SD Association. “SD can now support high definition video from Hollywood movie studios, television broadcasts, or HD videos taken on your latest vacation. SD is a very popular, extremely portable and easy-to-use storage medium that has enhanced the enjoyment and portability of music, photos and data. The Association remains committed to helping consumers maintain the value, usefulness and longevity of all of their SD products.”

Several of the products on display feature the recently announced Ultra High Speed (UHS) UHS-I and UHS Speed Class high-speed capabilities. UHS-I technology is found exclusively on SDXC and SDHC products. It offers faster bus-interface speeds, with data transfer speeds up to 104 megabytes per second. The new UHS Speed Class 1 technology offers a performance option designed to support real-time video recording. Consumers can realize the full potential of these technologies by pairing their devices and memory cards.
