    Nope.

    Thanks for the clarification.  I made that assumption because the problem showing up primarily in "older" cards and <128GB cards  seems contradictory.  (Though I admit that 128MB seemed TOO old to show up as a common problem.)  I would speculate that the vast majority of cards sold even today are <128GB, considering the cards that come with many products and the distribution of stock on store shelves last time I looked.

    This is not informative. lol
    So, "formatted the SD using the MBP and it burst into flames" ... would that be informative?  :smile: 
    I've heard of it not being mounted, or showing up with super-slow transfer speeds ... >frustrating<

    Not an easy topic to answer.
    My larger capacity USB 3.0 memory sticks with FAT 32 file system are working, but very slow.

    I tired to convert a 32GB memory stick to APFS, but it immediately failed.

    This is truely frustrating.

    • @auxio    What is a "better hub"?  Seriously, I'm confused about the available USB-C hubs and which will work or won't.  It seems like a real crap shoot.  Prices range from $40 - $360

    @MacCat20 Just saw this comment.  It's impossible to know for certain, but generally I stick with the ones which are listed in the Accessories section on the Apple website since they've typically gone through compatibility testing or certification from Apple.

    I'm having issues with my 14" M1 Pro and a small capacity SD card.  It mounts, I can see the files, but copying or moving them fails.  I'm going to try an external reader if I can.
