Is there a way to check the speed/class of a micro SD card?

It doesn't say on the micro SD's and I'd like to find out!

    The Speed Class Rating is the official unit of speed measurement for SD Cards, defined by the SD Association. The Class number represents a multiple of 8 Mbit/s (1 MB/s), the least sustained write speeds for a card in a fragmented state (Class 2, 4, 6) or the minimum non-fragmented sequential write speed (Class 10).[17]

    These are the ratings of all currently available cards:[14][24]

    Class Speed
    Class 2 - 2 MB/s
    Class 4 - 4 MB/s
    Class 6 - 6 MB/s
    Class 10 - 10 MB/s


    did that help??
  • Ahh yeah, found that but i'm on a mac at the mo lol. will try it on the parents laptop when I get a chance :)

    are the standards for a card to be called class 4/6/10 by law/legislation or is it different between manufacturers?

    The class ratings are industry standard. Whether manufacturers stickl to them is another matter. A Cheap Class 6 card can often be slower than a quality Class 4 card. As always, beware cheap ebay fakes.
    You only need two tools: WD40 and Duck Tape.
    If it doesn't move and should, use the WD40.
    If it shouldn't move and does, use the tape.
