What are the differences between SD, SDHC, and SDXC cards, and how do I choose the right one for my device?

SD, SDHC, and SDXC cards differ in their storage capacity and compatibility with devices. SD cards have a capacity of up to 2GB, SDHC cards range from 4GB to 32GB, and SDXC cards go beyond 32GB. To choose the right one for your device, check the maximum capacity supported by your device and choose a card that fits within that range.
