    Is there any use the more expensive class 6 or 10 Microsd card in the Rise, or just use a class 4? I am unsure of the class of the default 2 gb card.

    Thanks

    If the class number isn't shown on card in a white circle then it has a base speed (lowest) Having a higher class SD card makes the difference. The class refers to the write speed and how fast it handles data transfers (most notable for camera use and video recording). Keep in mind when getting a new SD card for the Rise that it can only handle 32GB on the SD card. So get a 16 or 32GB card and you should have all the space you need.

    The higher the class number the faster the write speed, most commonly used for video cameras.
    With Android Phones read speed is most important. The faster the read speed the faster your phone fully boots up ( the ability to use all apps and functions) and your SD card is read and fully functional.
    Read speed is not regulated and can vary widely. One manufacturer's class 4 might have a better read speed than another's class 10.
    Currently the Sandisk class 4 16GB micro SD card has the best read speed, averaging a little over 40MB/s
    The average SD card is in the 25MB/s range

    Note: These values are with an empty card and will come down a few MB/s as the card is filled.

    EDIT: SD Tools is an app found in the PlayStore that test the read and write speed of an SD card. Maybe members with different Manufacturer SD cards and classes could post their Card Info plus read/write speed in case there is a micro SD card that has a better read speed of the Sandisk I described?
