Tips:
How to check the capacity and speed of a memory card?
1. Use a high-quality USB 3.0 card reader for testing.
2. Please do not use cheap card readers to test Micro SD cards, as the speed of the Micro SD card may be reduced due to low-quality card readers.
3. The speed of a Micro SD memory card largely depends on the card reader, selected capacity, USB port, etc. Low-quality devices will 100% slow down the card's speed.
