Types by size

SD Memory Cards ie Secure Digital Memory Cards are available in full size, standard size and mini size.

Similarly, if users think that they will also save 4K recordings and RAW images, then UHS1 or UHS3 card is better. Class 6 and above storage cards are also ideal for general storage in DSLRs and point-and-shoot.
