UX31A (s)low transfer speed via USB 3.0

[paparazzo79]

I'm having issues with this laptop transferring files to external HDD 8 TB which on desktop PCs gives me transfer of up to 100-120 MB/s constantly.
On laptop is not HDD it's some sort of an SSD so that should not be an issue.
Ofc is not issue with external HDD since it gives me max speed.
All the drivers are installed I suppose okay (device manager pics).
There are no official drivers on website for laptop,so only W10 drivers are installed.
But 21-25 MB/s is not even USB 2.0 transfer rate.
So can anyone help me resolve this issue and get max speed over this usb 3.0?

Be sure you have the latest Asus tool to update your OS:

Perhaps it is a driver issue.

Haven't installed none of these.
W10 drivers.
I searched for Intel HM76 chipset drivers haven't found one on their website.
Yeah for sure it's driver or HW related.

No updates, running that software...

Search around on your logic board to see if there is possibly a different USB 3.0 host controller. Also, sometimes the motherboard designers will use a USB hub controller. Varying with the quality of the hub, you may face slowdown issues if the hub is mated with slower USB 2.0 peripherals. Do you have a USB 3.0 thumbdrive that you can test with the similar benchmark tool ? Have you tested other USB connectors on this logic board? Do they benchmark the same ?

The ports are marked with blue,which means those are 3.0.
Same speed on both ports,yeah used usb 3.0 devices,pendrives,external HDDs doesn't matter.
Maybe I need to update the driver but none of them I found.

USB 3.0 controller is integrated into 7-series PCH. Native Windows 10 drivers should work fine.
Try from Linux to see if it is a software issue only with Windows.

Good idea,but I can only boot from live distro which is using USB port so speed would be limited.
Agree?

If you use a USB 3.0 media to boot from, you should be fine to benchmark.

How many USB 3.0 ports on this box ?

Suspecting that you have a USB 3.0 hub controller between the PCH and this connector. Maybe the Superspeed interface lines are blown from ESD or similar event ?

Test on Linux and post your benchmark.

Only 2 USB ports.
It's not worth to do that because it will limit the transfer speed because one usb will be occupied with the usb pen drive containing live distro.

Transfer speed is greater..so it's W10 issue..wonder now what it is...
