Important Compatibility Tip
Before purchasing, please confirm your device supports the capacity you intend to buy. Inserting a card that exceeds your device's supported capacity range may prevent it from functioning correctly — this is a device compatibility issue, not a product defect. High-speed performance testing requires a USB 3.0+ interface.
