And the good part is that, there are huge in numbers.
Along with the enhancement in technology and decreasing in the price of electronics stiffs, very less of the device supports Class 2 memory. It’s poses a speed of 2MBps, Even, budget smartphone or camera supports Class 10 cards. So, it’s better to ignore buying Class 2 SD card or a card that do not poses speed Class markings shown above.
Class 4, 6 and 10
Class 4 is 4MBps, Class 6 is 6MBps, and Class 10 is 10MBps or faster. Various or you can say almost all camera and smartphones support Class 4 cards and above.

Ultra High Speed (U1, U3)
These cards are known by their ‘U’ along with the number referenced inside the alphabet rather than usual ‘C’. Although, if you are professional photographer along with professional DSLR, then you can go for Class 10 card, but you can’t go beyond Full HD video and can’t explore into the RAW shooting domain.

Although, full-size SD cards are somewhat faster as compare to small ones, but different device supports different sized SD card. And it’s very necessary to know how many can your device accept and how fast they need to be.
