USB throughput 3.0 very low on Win10 and ROG_STRIX_Z390-H_GAMING

Hello,

Since almost 1 month now, i try to solve my issue linked to my USB Key 3.0 with my new computeur built recently.

I got a USB key PNY 16Gb with USB 3.0 but when i plug it to my new computer and i try to tranfer for example 2 Gbyte file on it, on Win 10 i only to max 9 - 10 Mbyte throughput, while when i plug it on my ASUS labtop with win7 equiped also with USB 3.0 connector i got about 100 Mbyte throughput transfer with exactly the same file !!

Here is my Pc config :

Motherboard : ROG Strix Z390-H
On Motherboard :
- Last Bios update Version 1202 from 11th January 2019
- Last Chipset version 1815.12.0.2021 from 17th September 2018


Storage 1 : Samsung Serie 970 EVO, 500 Gbyte M.2 Type 2280
Storage 2 : Samsung SSD 860 PRO 512 Gbyte
CPU : Intel Core i5 9600K

My win10 information :
windows 10 Professionnel
version : 1803
OS version : 17134.556

this is the reference of my Usb Key :
https://www.pny.eu/fr/consumer/explore-all-products/usb-flash-drives/990-hook-3-0-16gb


What i can't understand on my ASUS labtop with win7 i got about 100 Mbyte transfer and on my PC i got abot 9 Mbyte.

I tried many things for example that : https://www.mediafast.com/improve-speed-in-slow-usb-flash-drives/

But not working.

I tested that from Window 7 :
https://support.microsoft.com/en-gb/help/2581464/driver-update-to-increase-the-maximum-usb-transfer-...

but not working too.

I can link also many other solution i tryed but i prefer to not spam too much.

almost 4 weeks trying and trying again some solution without any success.

so please if you have any idea let me know because i don't want to downgrage my PC to Win7.

Again i got very highspeed on my Asus Labtop with win7 (about 100 Mbyte transfer) and only 10 Mbyte on my new PC with windows 10.

thanks for your help.

Regards,

Alkashi

I had a similar issue with my MAXIMUS XI HERO call of duty edition, I did not check usb transfer speed but it was providing low power to all usb devices (causing wireless mouse to perform poorly unless its super close to the receiver)

Hello guys,

i just tried this solution :

https://www.thewindowsclub.com/slow-file-copy-speed-windows-10

but still it does not work.

If you have any idea?

Thanks,

Do you have another brand (not PNY) USB 3.0 stick or an external 3.5 inch usb 3.0 hard drive you can try to see if speeds are normal?
Maybe your motherboard or Windows 10 don't play nice together with the certain PNY usb stick you have.

Check your anti-virus software is not scanning all file transfers to & from usb. Just a thought, as this could dramatically reduce performance.
