    Tested it in an SD card adapter on pc with which reported onlt 117GB available. exFat file system

    These results ok?

    Assume you mean 117GB? Thats normal.

    That adapter is probably bottlenecking you, I find fast SD readers are actually pretty uncommon.

    Pop it into an Android smartphone (a new one) and benchmark it there.

    that much better!
    A1 SD Bench
    Longer Test, Read:79.35MB/s - Write 27.55MB/s (Cache hits flagged)
    Accurate with restart, Read:56.67MB/s - Write 30.26MB/s
    Random IO with restart: Read:32.42MB/s - Write 0.53MB/s

    seems to be exceeding the stated max write speed of the card...

    You've got me itching to upgrade my micro now, only rocking 20 R 10 W.

    If its rated to a class thats only a minimum, some of them will go over.
