USB 3.0 Speed is too slow on Hero X M/B ?

Hi all,
I have a problem with the speed of my USB 3.0
on my Asus Hero_X M/B.
Running both Windows 10 & 11

I am only getting transfer rates of about 38 MB/s at it's fastest.
The same USB stick used on my ROG Laptop gets speeds of 138 MB/s

My System is:
Intel Core i7 8700K
GeForce GTX 1080 Windforce 8GB Card
Samsung SSD 960 EVO 1TB PCIe NVMe drive
Samsung SSD 970 EVO Plus 1TB PCIe NVMe drive
WD 4TB BLACK X 2
Corsair Vengeance LPX 32GB
BIOS version: 2701 Date: 07/13/2021

I have tried plugging the USB stick into all the sockets on the front and back of the PC,
I also have some USB C sockets. They all return a speed of around 38 MB/s
I have uninstalled the USB Drivers and reinstalled.
I have checked the BIOS to make sure they are enabled.

Has Anyone got any Good suggestions in what might be wrong with the system?
Thank You......

P:S
I have just updated my Post here:
I installed Linux Mint to my PC
and the USB key is transferring data at 200 MB/s
So it can't be a hardware problem!
I would say it's a windows problem?
Drivers ?
Windows says it is using the best USB drive ?
I am Stumpted ??

It sounds like that USB stick is running at USB 2.0 speeds. Either it's a driver issue or that stick is not entirely compliant with 3.0 spec. If possible I would try a different 3.0 drive to see how it behaves.
A bus station is where a bus stops. A train station is where a train stops. On my desk, I have a work station…

xeromist , you are 100% correct,
It is the USB sticks which are faulty.
Tried them on a laptop,
which gave the same results, 38MB/s
As a warning to other people, here is the
model of the USB Sticks

SanDisk
Ultra-Dual Drive
Go 64GB
for USB Type-C devices an A Connections.
Up To 150MB/S

Here is the link the them:
https://www.amazon.co.uk/SanDisk-Ultra-Drive-Type-C-devices/dp/B07YYK13LF/ref=sr_1_3?crid=1AH4MI76YV...

I shall be returning them as "not advertised as such" !
Thank you, Happy New Year.........

Hi all,
As I started this post I thought I would
Close this topic as I have found the answer
To my original question.
And the answer is:
The
SanDisk
Ultra-Dual Drive
Go 64GB
for USB Type-C devices an A Connections.
Up To 150MB/S

Is incompatible with windows 11.

I showed this by installing this USB3 drive on a Linux Mint O/S
And it was absolutely flying.

On the Windows 11 the best I was getting was 38 M/Bs
Not much faster than USB2.

On the Windows O/S I inserted a Corsair Voyager GTX USB3 Stick
And got huge data write/read speeds.
And for good measure I inserted a SanDisk Extreme USB3 Stick
And got huge data read/write speeds.
So there we are.

So, do not buy a
SanDisk
Ultra-Dual Drive
Go 64GB
for USB Type-C devices an A Connections.
Up To 150MB/S
if you want to use it on a Windows 11 PC !!
I hope you find this article useful?
