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: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.May 29, 2016 at 4:13 am #38967Really 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?
May 29, 2016 at 8:15 am #38977Those 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.May 29, 2016 at 3:27 pm #39022Scanned to 100% and found no issues. But idk whats wrong, its like it wont read sdxc, or limited to sdhc or …
May 29, 2016 at 3:52 pm #39028Also, 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.
May 29, 2016 at 4:30 pm #39036Run
Get-WmiObject Win32_PnPSignedDriver| where {$_.devicename -like "SD Storage Class Controller"}
in PowerShell and compare with output in this postMay 30, 2016 at 5:15 am #39090ty 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.

Get-WmiObject Win32_PnPSignedDriver| where {$_.devicename -like "SD Storage Class Controller"}
in PowerShell and compare with output in this postI have an identical device in device manager, but another sd storage class controller with the failed to start code apperes when i insert te sdxc card.
May 30, 2016 at 7:01 am #39096Maybe 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?May 30, 2016 at 5:20 pm #39162I did try to disable what popped up, but no change and if u removed/reinsert the card the device comes back… ill try to post the details of that device today.

PSComputerName : CHUWI-HI8PROMay 31, 2016 at 8:16 am #39297Your 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.May 31, 2016 at 3:30 pm #39360yes, tried a 4gb and it worked no problem, tried two of those sdxcs from samsung and nothing.
May 31, 2016 at 6:54 pm #39377I’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.
June 1, 2016 at 12:15 am #39415? Not sure how, android reads them fine, so shouldn’t win10 also see them?
