"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.

The Association remains committed to helping consumers maintain the value, usefulness and longevity of all of their SD products."
