Class	Speed	Our opinion
Class 4	4MB/s	Too slow for most modern cameras. Skip it.
Class 6	6MB/s	A little bit better but unless you take 3 pictures a year, skip it.
Class 10	10MB/s	Good enough for most cameras with 20+ megapixels and Full HD video.
U1 (UHS)	10MB/s	Good enough for most cameras with 20+ megapixels and Full HD video
U3 (UHS)	30MB/s	Perfect for fast burst cameras, Full HD at 60fps and 4K video
