Hello.
I have 4 USB 3.0 ports in my G750JX. The speed of USB 3.0 is so slow. Here you can see it.
Can you help me to solve that?

Thanks for reading. 🙂33802

Make sure both are USB 3.0, if 1 is 2.0 then it wont go any faster.

Your speed will also be limited if you are copying to and/or from a HDD. For a large, sequential transfer I think it would be faster than that (probably somewhere from 50 to 100 MB/s), but if you're transferring a bunch of smaller files I think it's possible to see speeds as low as you are even if everything is functioning properly, particularly if it's a slow HDD (5400 rpm). I could be wrong though.

I'm tranfering files from SSD to 16GB USB with USB 3.0 port. How come it is USB 3.0??
USB 3.0 speed is around 50-100 Mb/s.
My speed is 10 Mb/s ...

I am also facing this problem, few days back i was transferring file from the laptop to a USB 64 GB and the speed was 100 + MB/s but today on the same system, same files and same USB the transfer speed is 10 MB/s, its insane 😞

I also have that issue. I transfer single file of 2gb with speed of 10mb/s.
I did experiment, copy from usb3 to usb3 and it is not so much faster, about 14mb/s.
Anyway, when I copy from usb3 to HDD is 130mb/s.
I'm kind of confused why is this happen?

Make sure the BIOS is the latest revision (v209 for the G750JX), and that XHCI Pre-Boot Mode is enabled in the Bios (Advanced-> USB Configuration -> XHCI Pre-Boot Mode -> "Smart Auto").
