Are these four USB 3.0 ports the same speed? Would it make a difference which ones are used for fastest connection?

This is a picture of ports on the back of my PC. I am just wondering if it matters which ones I use for external drives or USB flash drives.

Thank you for your help.
Update: Why are they colored differently around the plugs? Why are two all blue around the plug and the other one green and one not colored but with that blue ring?

Is the BIOS Flashback the only plug somehow connected to the BIOS for flashing yet still 3.0 too?

Just curious.
