ASUS Z370 OS HD Preferred SATA Port?

[achary1]

I cannot find documentation on the correct SATA port to connect my OS SSD to on an ASUS PRIME Z370-A motherboard. Some research suggests that the Z170 motherboards used port 3 as the preferred connection. Does anyone know if there is a preferred port for the Z370?

With UEFI it doesn't matter which SATA port is used.

Their all on the same controller so it don't matter.
The only time it would matter is if it had 4 ports on the chipset then 2 or more additional ports by a separate controller like some of the older boards had then it would be best to use the chipset not the added ports.
