The SD Association has announced two new high-speed performance symbols for SDXC and SDHC memory cards and devices.
The first symbol identifies devices with a new "ultra high speed" bus-interface performance up to 104Mbps, and the second symbol identifies SD cards and products with the ability to support real-time video recording.
These new performance symbols are used exclusively on SDXC and SDHC products.
"With more than 2.5 billion SD memory cards in the market today, the new high-speed performance capabilities will co-exist with earlier SD memory cards still used by consumers, as those older cards are still compatible with the newest devices," says the SD Association.
