Question: what is the difference between hc and xc micro sd cards?
Answer: As requirements for higher capacities came in, SD cards have grown in capacity too (SDHC is SD High Capacity, while SDXC is SD Xtended Capacity). SDHC cards typically come in capacities between 4GB to 32GB. SDXC cards come in sizes of 32GB of higher, with a theoretical maximum of 2TB.
