    Hi All

    OK Stupid question but I know SD Cards have speed numbers meaning 1 is slowest and 10 is higher (Not highest) and so on that I know.

    But is this only the WRITE speed? Meaning lets say I am on a flight and want to play a movie during the flight will a level 1 disk play the movie the same as a level 10 being it isn't writing to the disk or would a level 10 disk be far better for even playing movies or games that might be stored on the SD card?

    ocnbrze DON'T PANIC!!!!!!!!!

    each card has different read and write speeds. those numbers you are referring to are the class of the card and does not tell you what speeds they actually are.

    Dannydet and mikedt like this.

    OK I'm confused lets try it this way might just be easier.

    This is the tablet I bought. Mainly gonna use the tablet for reading books, Watching Movies on flights and potentially some game play via games in google play store.


    These are the 2 cards I am currently considering.


    So will either or both of these cards work fine for this or..... If not is there one that would work better in the 256+ range? Price is a factor so prefer lower price if possible

    mikedt 你好

    I think as long as the actual READ speed of the micro-SD exceeds the speed bandwidth required by the whatever it is movie files you're playing, Which just about all should do, unless you're playing something crazy like 8K movies, that requires extreme bandwidth.

    WRITE speed doesn't matter if you're just PLAYING video files. .
