New storage standard enables 4K capture via camcorder

To bolster the 4K ecosystem for camcorders and non-professional applications, the SD Association has announced a new high-performance option and symbol specifically designed to support a wide array of 4K television and video products.
The Ultra High Speed (UHS) Speed Class 3 (U3) symbol will indicate products capable of recording 4K video. 4K UltraHD quadruples the number of pixels in a video, requires eight times the amount of bandwidth to carry it than HD 1080p and represents monster files when captured.
"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 4K video formats. Both SDXC and SDHC memory card standards already offer the massive storage needed to support 4K video with enough room to store photos, music, documents and other data on a single portable card."
The UHS Speed Class 3 defines a 30Mbps constant minimum write speed to ensure high-quality video recordings. This means 4K video, live broadcasts and content can be recorded on high-performance cameras such as Digital Single Lens Reflex (D-SLR), Digital Single Lens Mirrorless (D-SLM), camcorders and video cameras and then played back smoothly.
New devices offering the UHS Speed Class 3 will be backwards compatible and will work with existing SD memory cards.
