[RESOLVED] slow usb 3.0 speeds

for some reason when I transfer any file my my 32gb usb stick (that is a usb 3.0) I don't get more than 12.5 mb/s but when using the same stick on my MacBook Pro 13 late 2013 file transfers are like 5 times faster ( don't know the speed at which it transfers).
My windows based pc has a Gigabyte Z370 ultra gaming motherboard. I tried to search drivers for the USB port but it seems like Gigabyte only has drivers for usb 3.1 type c

when I start to copy a file it starts at 40 to 60 mb/s then 2 seconds in the copy it starts to throttle and goes up and down from 3 to 12.5 mb/s. it seems like its hitting a limit. don't know what to do more. if anyone can help me, please help me

Try running this and see if it can find USB 3.0 drivers

Also, try booting Linux on your PC and test is the speed fast enough

There are no usb drivers for Win10. This os handles all the drivers for usb chipsets.

The usb flash drive is just a slow one most likely.

OP said that it works on MacBook. So it's not the USB that's slow.

It can be the files also. Let's say you transfer a few large mp3 or a large movie file, they in general should have a decent steady file transfer speed. But then let's say you have a ton of really small files. It might not get such good speeds with a larger number of small files due to how the caching works for small files and such and thus it slows down during the process or jump around between a decent speed and a slow speed.

You can only get up to the max rated speed but again it's not always going to get that at all times.

I would also do a test with the same file transfer, one test on a rear motherboard 3.0 port and then wipe the drive (or delete said files) and do the same test again via a front 3.0 port and see if the front usb just happens to run into such issues compared to the ones directly on the rear of mobo

i tryed to use the port on the back but still the same so i guess i can't really do much more

And Eldin, i used driver booster 6. I have some outdated drivers (somehow) but none are for usb

thanks for everyone who commented :)

flash ram/drives are slow

disk test with hdtune or aida

iv had a few sticks that do not like to be re-formatted, changing from fat32 to ntfs or exfat makes them dirt slow, and need to use the tool to format them back to stock was the only fix

If it works well on MacBook, try it on Linux on your PC.
You don't even have to install it, you can live boot.
If you have another USB drive, make bootable Ubuntu USB.
Then you can test your USB 3.0 speed.

Which drivers did you manually install and which ones did you let Windows handle?.

i didn't let windows install any drivers
i unpluged my ethernet cable and got the drivers needed from the gigybyte website for my motherboard. (got the drivers on another pc and put them on a usb drive)
