The reading and writing speeds of an SD card are gauged by their megabits per second (MB/s or Mbps). You can see this number on the front of the card. This chart is a benchmark comparison of some of the most popular SD cards in the market. It will help you to see the difference between a good and bad memory card.
What is a good speed for SD card?

What is better UHS 1 or UHS 3?
UHS Speed Class 1 supports a minimum 10MB/s write speed, whereas UHS Speed Class 3 supports at least 30MB/s write speed. The UHS Speed Class is denoted by either a 1 or 3 inside of a bucket U symbol. As a rule of thumb, 4K-capable camcorders will usually require at least a U3 rated SD card.

Does the SD card affect picture quality?
Memory cards have no effect on image quality, they just record 0s and 1s. Any major brand will work well with the possible exception of Lexar. Speed of the card has little to do with speed of the camera. If the camera doesn’t send the data fast enough, the card speed is totally irrelevent to image capture.
