[FFmpeg-user] Windows 10, ffmpeg concat/demux is slow... part 2

[Kevin Duffey]

Are you sure you are using a USB 3 port?
My laptop has both USB 2 and USB 3 ports.
I use the USB 2 ports for things that aren't as speed sensitive like the 
dongle for my wireless mouse/keyboard and the USB 3 ports to connect 
external drives and phones for file transfer.
Perhaps you are plugged into a USB 2 port.

My laptop only has USB 3, and 3.1 gen 2 ports. My SSD is in a drive bay connected to the USB 3.1 gen 2 port, and the reader unit is capable of 10Gbps connections.
