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
*Please don\'t use cheap card reader to test Micro SD card, speed of Micro SD card will be affected by low quality card reader（With high-quality 3.0 card reader and PC-side 3.0 USB interface）.
*The most reliable software to verify memory card is H2testw.
