As we’ve explained above, SDHC and SDXC cards don’t really have any different functions, and they’re not physically different formats. They simply have different storage capacities. So, with that in mind, know that this entirely depends on your personal preferences and needs. If you require a larger storage capacity from your MicroSD card, you will definitely want to go with the SDXC — the former is only capable of storing a maximum of 32GB. Though, this can also be enough for high-res photography — but not as easily for 4K videos.
