387 views

The key difference between SanDisk SDHC (Secure Digital High Capacity) and SDXC (Secure Digital eXtended Capacity) lies in their storage capacity and format. SDHC cards offer storage ranging from 4GB to 32GB and use the FAT32 file system, making them suitable for moderate storage needs. On the other hand, SDXC cards start from 64GB and can go up to 2TB, using the exFAT file system to handle larger volumes of data efficiently. This makes SDXC cards more fitting for high-resolution video recordings and extensive photo collections.
