What speed does this microSD card slot support?

    I have a Lenovo Miix 520 tablet with a microSD card slot. Looking at the specs (see attached PDF), I see it will support cards up to 2TB; but it says nothing about the speed it supports. I want the fastest read and write speeds I can get; but, I don't want to spend $200 on a UHS-3/U3 card if it supports only much slower rates (which would be a $50 card).

    (I'm looking at 512GB cards.)

    So, my knowledge is limited on this subject. Does anyone see anything in these specs indicating the speed the microSD card slot supports?

    I'm guessing that since it says nothing about speed (that I can tell), it's probably the slowest.

    In case it matters, mine has the i7-8550 processor.

    From all of the specs that I can find, even the User Manual, the speed is not listed.

    Thanks for that. I already decided if there was a way to interpret differently, it had to be something beyond my understanding. I assume that since the speed is not listed, it has to be limited to a low level as if it were not, they would certainly be bragging about it in the specs.

    I guess I'll go for one of the cheaper cards. I intend to use it as a permanently-attached extra partition.

    It does have USB3, so I wouldn't expect it to be super slow. Also, while I certainly understand not wanting to overspend, if the card would ever get moved or used in other equipment, it could pay to have a faster card.

    Thanks.

    I thought of that; but I already have all the cards I need for other devices and anything I get henceforth will likely be capable of speeds beyond what is available for microSD at present.

    And the price difference is two times more for the faster cards, minimum about $80 and faster about $160.
