question about usb cables

[tremmor]

Now im curious. I have some usb3 hardware like external usb3 hd.
I plug into a usb3 port on the computer. my question is are all
usb cables the same for usb 1, 2 or 3. Or do they actually make a usb 3 cable.
I have maybe 20 usb cables laying around and guessing they are all good.
Just want to make sure i get the usb3 speed with the older cables.
thanks

Usb 3.0 cables will usually have a blue color instead of a black color inside the connector.

Example here.

What is the difference between the one your showing and a regular usb cable.
Guessing its wired the same but just a higher quality wire. Ill buy one if it will make a diff.
Else i will just use what i have and let it go.
thanks

The end connecting to the device usually differs on USB 3.0 as well as being blue in color.

This wiki image shows it easier. There are 9 wires for USB3. It keeps the 4 from connectors from earlier specs for compatibility and adds 5 more in behind.
