A:Answer The red is a more professional series. The red cards is an UHS (Ultra High Speed) processing card. It can process photos even faster, take pictures faster, process the clarity of an image much faster and better (saying that it does a great job capturing 4k images and painting the resolution and processing the photo/videos really fast). It's just a better processing SD. This SD card is very fast and processes very quick, BUT, the red one will do much better when it comes to 4K resolution pictures and videos.
