Understanding speed classes

The SD card association defines card speeds using two terms: Speed Class and UHS Speed Class.

Speed class is the original rating used and the number defines the card speed, 4 for 4MB/s, 6 for 6MB/s. 10 for 10MB/s etc.

UHS (Ultra High Speed) uses minimum write speeds to differentiate the cards, UHS-I Speed Class 1 has a minimum write speed of 10MB/s while UHS-I Speed Class 3 has a minimum write speed of 30MB/s.

Speed based on internal testing, performance may be lower depending on host device, interface, usage conditions and other factors. 1MB=1,000,000 byte
