What is the difference between SD and microSD cards?

SD cards and microSD cards primarily differ in physical size and compatibility. SD cards (Secure Digital) are larger in size and typically used in cameras, camcorders, and some laptops. On the other hand, microSD cards are significantly smaller and widely used with smartphones, tablets, action cameras, and other portable devices. Despite the size discrepancy, both SD and microSD cards offer similar storage capacities and performance levels. Additionally, most microSD cards come with an adapter that allows them to be used with devices requiring a standard SD card. It's essential to check your device's specifications to ensure compatibility before purchasing the appropriate card.
