FAQ
What memory card do I need for 4K video?
Look for a U3/V30 rated card at minimum; higher V-ratings give more headroom for high-bitrate or 8K footage.
Why do counterfeit cards matter?
Fakes claim false capacity and speed and can corrupt data. Buy from reputable sellers and test new cards before relying on them.
