SDHC (Secure Digital High Capacity) cards range from 4GB to 32GB in storage capacity, while SDXC (Secure Digital eXtended Capacity) cards offer 32GB to 2TB. The main difference is the file system: SDHC uses FAT32, whereas SDXC uses exFAT. This affects compatibility—ensure your device supports SDXC if opting for higher storage. Investing in an SDXC reader ensures compatibility with both SDHC and SDXC cards, providing greater flexibility.
