memory card

This term refers specifically to the physical hardware used for portable data storage. It is distinct from internal memory or RAM, as it is designed to be removable and transferable between different devices.

In technical contexts, users often specify the type of card, such as SD, microSD, or CFast, to indicate compatibility. While the term is generally neutral, it is frequently associated with capacity (e.g., "high-capacity") and speed classes in consumer electronics marketing.
