“What does the A2 rating mean? Doesn't that have to do with app capability? And what does the 2 represent in app capability if that's what it means on micro SD cards”

The Application Performance Class specifies a minimum sustained write speed of 10MBps, along with a minimum random read and write speeds measured in input/output operations per second (IOPS). This guarantees an acceptable level of performance when using the memory card. There are two classes: A1: Minimum random read speed of 1500IOPS; random write speed of 500IOPS. A2: Minimum random read speed of 4000IOPS; random write speed of 200IOPS.
Sorry, there was a problem. Please try again later.A2 The app performance class 2 (A2) is defined by SD physical 6.0 specification. It makes the card much higher performance than the A1. In other words it works ay a higher rate of speed and gives you a clearer picture.
