    Why do some Extreme III and IV cards have different read and write speed, also, what is the difference between SDCFX3-4096 and SDCFX3-004G?

    SanDisk has recently increased the speed of the Ultra II, Extreme III, and Extreme IV memory cards.

     

    Old Speed

    New Speed

    Ultra II

    10MB/s

    15MB/s 

    Extreme III

    20MB/s

    30MB/s

    Extreme IV

    40MB/s
