    Speed Class<\/strong>:<\/p>\n

    If you do professional photography and save photos in RAW format or want to take high-resolution videos and save them on the SD card then you will require a fast memory card. However, if your requirement includes taking simple photographs and saving media file on a phone then you need not bother about the speed.<\/p>\n

    There are four speed classes available, starting from 2 up to 10. Classes 4 to 6 are good for HD video recording while Class 10 SD cards are excellent for full HD recording. There are 2 classes for ultra high speed as well but these can be used in devices which support such cards. However, if there is no symbol on the card for its speed then it is likely that it was designed before the rating system started and is probably a class 0 card with speed even slower than a class 2 memory card.<\/p>\n
