USB Port Information

What type USB port is on the UBook 11.6 4100? I have a USB 3.1 (solid state Samsung T5) drive which reaches 500+ MB/s read/write speeds on my other computers. Unfortunately, it reaches < 100 MB/s read/write speeds on my UBook.

Are the ports 2.0 or 3.0? My understanding is that USB 3.0 and 3.1 are the same thing except for the name.

Thanks

The USB port of UBook 4100 is 3.0.
