The SD Association has revealed their fastest speed class called Video Speed Class, which also delivers real-time multi-file recording (4K, 8K, 3D and 360 degree video recordings). Additional information:
The new Video Speed Class maintains the tradition of ensuring guaranteed minimum performance levels as the familiar Speed Class and UHS Speed Class systems do today. Minimum speeds will range from 6MB to 90 MB per second. The fastest options, V60 and V90, support 8K resolution, while V6, V10 and V30 capture high-definition and 4K resolution. All speed classes guarantee minimum video recording speeds to ensure smooth video playback, so actual recording performance may be even faster.
