Hi, I have the mentioned notebook and I've tried copying files from an USB3.0 drive. And the top speed is an abysmal 35MB/s.
The drive was connected to the SS marked port, and is known to be capable well in excess of 200MB/s on other computers.
Why is this happening? The OS is the pre-installed W10 home, with the default microsoft drivers installed, intel says they're not releasing usb drivers for windows 10 because the ones supplied by ms are fine. Well apparently they're not.
