What does all that stuff mean on an SD memory card?

The information on an SD memory card typically includes its storage capacity, speed class, and other specifications. The storage capacity indicates how much data the card can hold, while the speed class rating (like Class 10, UHS-I, or UHS-II) informs users about the minimum write speeds, which is crucial for tasks like recording high-definition video. Additional markings may include the card's version (like SDHC or SDXC) and compatibility with devices. Together, these details help users choose the right card for their needs.
