Faster SD cards on the way as part of 4.0 standard

Announced last week at IFA is a new dual-row pin design for SD memory cards, allowing transfer speeds of up to 300Mbps between devices and removable storage media.

The new SDXC and SDHC cards, which will be available in both standard and micro forms, will use the second row of connectors to handle high-speed interface signals.

While the new connectors will be used on forthcoming cards and SD-compatible devices, as part of the SD 4.0 specification to be formalised early next year, the format will be fully backwards-compatible.

The cards will be the same size, meaning that all devices can make use of any SD, SDHC or SDXC memory card.

Norm Frentz, chairman of the SD Association, says that the new design 'lets consumers using equipped products manage the massive storage capacity found on SDXC memory cards at incredible speeds.

'SD can now support high definition video from Hollywood movie studios, television broadcasts, or HD videos taken on your latest vacation.'
