Windows 10 Slow USB 3.0 Transfer Speeds

Q. I recently upgraded to Windows 10 from Windows 7 on my gaming rig. Here are some specs:

Intel i5 4590 @ 3.30 GHz

16.0 GB RAM

Nvidia GeForce GTX 960

ASUS B85M-G motherboard

120 GB Samsung EVO 850 SSD

1 TB Western Digital HDD

I tend to copy a lot of stuff onto USB drives to put into my media player in the living room. I have two sticks I use, a Kingston 16GB USB 2.0 stick and a San Disk 16GB USB 3.0 stick. Since updating to Windows 10, regardless of which stick I use (I’ve tested both and on all ports in my machine) I get very slow transfer rates compared to when I was on Windows 7, even for a USB 2.0 drive. I’ve attached a picture for reference:

I used to get around ~20-30MB/s on Windows 7 and now I’m getting about half that at best with a lot of fluctuations. Anyone else has this problem? I’ve read that it’s a driver issue between Microsoft and Intel where Microsoft has drivers for USB 3.0 controllers but they aren’t…good? Intel doesn’t seem to have any drivers that would be supported by Windows 10 when I searched their site. I really don’t want to go through the hassle of going back to Windows 7 because there is a lot I like about Windows 10 but I do use the flash drives frequently enough that this is a big reason for me to go back to Windows 7.


I suggest you install the latest USB port drivers from the ASUS website and check if it helps.
