The new Ultra High Speed (UHS) Speed Class 3 (U3) symbol will indicate products capable of recording 4K2K video and will operate exclusively on SDXC UHS-I and UHS-II memory cards and devices and SDHC UHS-I and UHS-II memory cards and devices.

This SD card class defines 30 MB/s constant minimum write speed to be able to make such recordings without issues.

"The world's favorite SD memory card continues to evolve and meet shifting industry needs," said Brian Kumagai, president of the SD Association.

"Our new UHS Speed Class 3 standard will give consumers and businesses more flexibility and capability as the market shifts to 4K2K video formats. Both SDXC and SDHC memory card standards already offer the massive storage needed to support 4K2K video with enough room to store photos, music, documents and other data on a single portable card."
