Update 2:
Ok. So I've plugged the BX100 into the ASMedia ASM1061 ports on the board (SATA3_A1/A2) and it detected it perfectly and is now showing up in windows and is fully useable.

I've ran some benchmarks and the drive is slightly under performing due to the fact it's on a 3rd party chip rather than native like the rest. 

However it's now proven it isn't the drive itself at fault.

I also did a little bit of digging regarding the 2 drives mentioned having compatibility issues with SATA ports 1-8 (AMD native) i.e. BX100 and the Mushkin Reactor drives and noticed they both have the same controller in common i.e. - Silicon Motion SM2246EN

The MX100 uses a Marvell controller and the Samsung EVO 850 uses its own samsung controller.

Perhaps it's an issue with the main SATA ports not liking this certain controller?

Looks like an issue with this particular controller and X370, maybe something like Z87 and Sandforce controller issues, didn't detect unless you restart just like I'm having now.

Thanks for providing the information about the Reactor and BX100's SSD controller, I was not aware of that.

It was the Sandforce 1200 series SSD controllers that have the problem with the newer Intel SATA ports. The OCZ Vertex II is an example of an SSD that used the Sandforce 1200 series controller.

Just being clear about this, since the Sandforce 2000 series SSD controllers do not have the same problem. I don't want people with SSDs that have the 2000 series Sandforce controller (many Intel SSDs, 520 and 530 models) wondering if they will have problems.

I believe it was never clear whether or not the problem was a hardware issue (the chip design itself) or a firmware problem. I vaguely recall it was the chip itself, but I may be wrong.

But I believe at least part of the problem with the 1200 series controllers was they did not support a new revision to the SATA specification, that was not backwards compatible. The new Intel SATA ports supported that new SATA revision. Whom would we say is at fault in a situation like that? Or is it not a fault, just a compatibility reality?

It might be the case that the Silicon Motion controller does not work well with the Ryzen SATA chipset. I'm not comfortable saying that is true at this point, and I'm not saying that you are. But things like this have happened, such as the example above.

I've used an older Samsung 830 with the first two AMD SATA ports, an Intel 530, and the MX100. Those work fine. I'll try an OCZ Vertex 4 next.
