Premium quality What does 633x mean on a SD card? Speed Rating: The “633x” is a legacy way of expressing read speed. It’s being replaced by more modern ratings like UHS Speed Class and Video Speed Class. UHS-I Compatibility: Cards labeled with “633x” often also use UHS-I technology, which means they can achieve higher read speeds. Minimum Write Speed: While “633x” focuses on read speed, the UHS Speed Class or Video Speed Class ratings (like U1, U3, V10, etc.) indicate the minimum sustained write speed. Not an Indicator of Write Speed: “633x” is primarily for read speed and doesn’t guarantee a high write speed.
