    I've searched everywhere, but there isn't any concrete information on Lumia's real support for faster Micro SD card types.
    In the phone specification pages, I only see that it's compatible with "Micro SD", but that is too vague.
    I know that any card that I put in my phone will work, but I don't know which card types will really make a difference for anything.

    Basically, I want to know which Micro SD card types a Lumia phone can really handle (where handle = use its full speed) (by card types I mean class 6, class 10, UHS-I, and so on).

    By the way, I own a Lumia 640 phone.

    Ever get further on this? I, too would like to know if I'm throwing money out the window with a class 10, if all I truly need is a class 4.

    Just bought a class 10 UHS-1 card.
    Tested it in my computer (manually copying big files).
    Its write speed was more than 2x faster than that of my old class 4's.
    In the other hand, read speeds was identical, so I guess I threw some somey out of the window. :p
    Not that much, though, since I did need a 32GB card anyway, and the UHS-1 class 10 was just about 15 bucks more expensive.
