SATA Port Numbering

Easy way to discover.

Plug one in to either 1 or 2 then go into the BIOS to see which port it is on.

I can't post an image because this site won't host it, but as you look down the 2 columns of SATA ports in the manual, it lists 1,3,5,7,9 as left and 2,4,6,8,10 as right.  In actual fact, if you were to stand the motherboard up and look directly into the connectors, it's the opposite way around.  Closest to the motherboard is 1,3,5,7,9. Why or how they screwed this up I don't know. Something else that got me when I started was the orientation of the CPU installation.  The socket and CPU are actually rotated 90°.  You read the word Ryzen with your head tilted over to one side. I took a look on youtube but ultimately I just looked for the little triangle.  Done.

Huh?

This pic shows 2-4-6-8-A2 closest to the MB. Same as the manual on the block diagram and on pg 28.

This is what it looks like in the manual:

Yeah, well they are what they are.  Most USB 3.0 ports are provided by them due to the fact that we've had hubs on boards.  Windows device manger will say root hub or such.

For the X370, they are exactly as I described. UEFI will show which drives are where.  If you have multiple drivers of the same brand and product code you'll have to use software in the OS to find that out.  HWinfo for Windows is rather good at finding all the sensor info.  It told me the serial number of each of the two 1TB Seagate HDDs I have, same model drive, two different serials.
