    I used Samsung EVO+ 128GB micro SD card for this quick benchmark.
    Measurements shown below were done in Chuwi Hi8 Pro and Surface Pro 3, respectively, with the same card to remove possible bias:

    Chuwi Hi8 Pro

    Surface Pro 3

    You will probably notice I wasn’t patient enough to wait for Chuwi to finish with last test, but you get the idea.
    I find it funny that Hi8 Pro is faster than Surface when it comes to 4K operations.

    Really now? I got one of these and android loves it but Win10 fails to read or load it,  says it fails to start.  Can u send me ur chuwi sdstor.inf and sdstor.sys from ur system32 folder?

    Those drivers are integral part of Windows, they are not ChuWi specific. Just doing sfc /scannow should fix any corruption there is. Let me know how it goes.

    Also,  i was able to flash the bios from the sdxc card.

     

    edit: and windows can read the card from another adaptor via usb port,  but not from the sd card slot.

    Run Get-WmiObject Win32_PnPSignedDriver| where {$_.devicename -like "SD Storage Class Controller"} in PowerShell and compare with output in this post

    ty for the help.  new info –  if i change sd support in the bios on the chipset tab under south bridge to PCI, WinX sees the card now (though it seems buggy) but android cannot! i can flip the setting in the bios and it always has this effect.

    Maybe you should remove the problematic extra driver that appears when you insert the card.
    Does that sound like a good idea?
    Can you get more info on that other driver?

    Your drivers are exactly the same as mine.
    Did you try using some other SD card in Windows?
    I can attach my sdstor.inf and sdstor.sys for you, but I don’t think that is going to solve your problem.

    yes, tried a 4gb and it worked no problem,  tried two of those sdxcs from samsung and nothing.

    I’m not a SD card expert, but is it possible that these cards are damaged in some way? I think we pretty much ruled out the drivers and Chuwi card reader itself.

    ? Not sure how, android reads them fine, so shouldn’t win10 also see them?
