X570 Sata Speed - known issue?

[RandomMonkeH]

I stumbled on this while trawling t'web and comparing chipsets

Anybody run into this issue or know if there is any validity to it. Seems like quite a few people corroborate it. Performance in B450 and B550 appear fine.

Good post didn't know anything about this.
Was thinking of buying a X570 motherboard too.
