SD card labeling for 4K video announced
As of now there are not many consumer products, aside from a few smartphones (and the GoPro HERO3+ Black Edition), that can shoot 4k video. However the SD Association's announcement of new Ultra High Speed Class 3 (U3) card labeling anticipates it becoming more common.
It's mainly been a format for more expensive pro-level equipment because of infrastructure bandwidth, but by guaranteeing a write performance of at least 30 MB/s of constant minimum write speed (or 240 Mbps in bitrate terms), it will be easier for customers to know which cards are fast enough and potentially make shooting 4k more accessible.
