The UHS Speed Class 3 defines a fast 30 Megabytes per second constant minimum write speed to ensure high-quality video recordings. This means 4K2K 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. Consumers will benefit from a single card that is capable of meeting all of their video, photo, music, document and data storage needs, the Association said.
New devices offering the UHS Speed Class 3 will be backwards compatible and will work with existing SD memory cards.
“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.”
