Chuwi Hi10 Pro very slow SDXC card ( 20MB\s )… What is your transfer rate?

[Oleg]

A few days ago I bought the Hi10 Pro with the Z8350 CPU (serial number begins with HQ64G…) My BIOS version (CPU-Z) is 5.11 from 11. october 2016.
I have already read that there are some SD-card problems with the Hi10, which were solved with a new BIOS version.

I have a 128GB micro SDXC card with a speed of 95/90 MB. I tested in in an other device and the rates are okay.

When I tested the SD card in my tablet, I had transfer rates of about 19-21 MB/s read and write. I tested an other 16GB micro SDHC card and had the same results… I already installed all windows updates and the drivers from CHUWI forum, but nothing changed.

The transfere rates are same in Android, so I think its not a driver problem. Maybe BIOS version or some missconfigured BIOS settings (stock settings, no changes were made)?

Is here anyone with the same issues? What is your transfere rate from micro SD card?

Can someone please tell me if the 20MB\s is normal in this tablet or not? Thanks

You should feel lucky that is working as it is. So many people had have big issues to work the mini sd feature especially under windows os.

Fair enough. but as an extension for the tablet a sd card with < 20 mb/s read write speed is not fun.

I have a Chuwi HiBook pro + Toshiba SDXC UHS-I 128 GB card (M302).

At maximum i get ~12 MByte/s write and ~17 MByte /s read speed.

What is very Poor even if it would be connected as usb 2.0 device it should be able to do 480 MBit / s  –> 60 MByte / s.
