These UHS bus interfaces indicate the theoretical maximum read and write speeds, unlike the sustained write speeds of speed classes. The UHS bus interfaces are denoted by a Roman numeral “I” or “II” symbol on the front of the card. The bus speeds refer to the theoretical data transfer rate of the interface itself while a U3-rated SD card has its own sustained write speed of 30MB/s. For example, a UHS-I U3-rated card guarantees a write speed of 30MB/s but has the potential for a read and write speed of up to 104MB/s if used with a device that supports a UHS-I bus interface.

SD cards rated at V30 usually have a write speed of up to 30 MB per second while V90 cards can reach up to 90 MB per second. In this case, V90 cards would perform better especially on sequential burst shots. The camera’s buffer would clear significantly faster when you are using V90 cards since it has a higher burst write speed. SDXC V60 cards are tested and certified to operate at a minimum sequential write speed of 60MB/second, while SDXC V90 cards are certified to operate at a minimum continuous write speed of 90MB/second. The prefix V refers to the video speed class as specified by the SD Association for denoting the sequential write speed offered by each of the card standards.

The UHS Speed Class is more commonly used nowadays than the Speed Class and many high-end cameras require at least a U3-rated memory card for many of its functions, such as recording high-resolution videos. The UHS Speed Class mainly refers to the minimum sustained write performance for recording videos and came about due to 4K-capable video recording devices needing faster write speeds. As a rule of thumb, 4K-capable recording cameras will usually require at least a U3-rated SD card.
