Is there a tool to test the speed of a particular USB port?

I'm looking for a tool to find out what speed my USB ports offer, which are USB 3 or USB 2 (unfortunately they are all black and not color-coded).

I have the feeling that 2 of the laptop ports are USB 3 and the third port on the other side only USB 2, but I'm not sure.

if anyone of you knows such a tool (possibly free), it would be nice to introduce this to me with the name of the tool and possibly link there.

You can connect a USB 3.0 stick and run a benchmark with the Priogram CrystalDiskMark. Then you can exclude according to the speed, at least in the fast, that it is a USB 2.0 port.

You do not need a tool for that. Kopere test a larger video sequence on usb on the computer and it will show when copying in - "show more" or properties, the transmission speed.

In addition: if you go with a fast USB3 disk via USB to the calculator and the 2er socket caught, you get the message from the computer, … This plate allows a higher data rate…

Ah, good idea.

means I have to look if I nen USB 3 stick or external hard drive, which is usable and then test with the CDM.

good reference to the test tool, which I think even loads as PortableApps.

more tips on tools are of course welcome.

The hint comes sometimes, but sometimes not. So I'm not sure about the one port.

also the speed varies at the port.

a hard drive also shows a green instead of a blue LED on this port. That gave me the idea that this port is not USB 3 capable.

With USB 2.0 you are (in practice) limited to roughly 20-25 MB / s.

With USB 3.0 ("SuperSpeed") (theoretically) up to 300 MB / s should be possible.

If a USB3.0 stick, or HD significantly more than 20 MB / s reaches, it is clearly a USB 3.0 port.

With this you can determine the reading and writing speed of data carriers:

Which laptop do you have exactly?

And what does the manual say?

Once USB 2.0 could make sense. That's enough to connect a mouse.
