MicroSD markings indicate card capabilities

MicroSD card markings indicate storage capacity, speed class, bus speed, and application performance, as defined by the SD Association. These indicators help users identify a card's capabilities, such as its maximum storage (e.g., SDXC for up to 2TB) and minimum sequential write speed (e.g., Class 10 for 10MB/s). Understanding these specifications ensures compatibility and optimal performance with various devices.
