It seems inevitable that chipset lanes are degraded vs native lanes, but by how much? Comparinga pcie 4 nvme on each type of nvme port seems a good test, & pertinent to many nvme buyers.

Peter is saying that the two NVMe ports are powered by different “grades” of PCIe lanes. One port is powered by native PCIe 4.0 lanes from the CPU, The other is powered by PCIe 4.0 lanes coming from the chipset. The Ryzen 3 series has 24 lanes of PCIe 4.0 connectivity. (Check Anandtech article here: https://www.anandtech.com/show/14161/the-amd-x570-motherboard-overview). The breakdown is 16x for graphics, 4x for NVMe, 4x for the Chipset link. The chipset offers an additional 24 lanes of PCIe 4.0. But all of those are bottlenecked by that 4x link between chipset and CPU. So one of those NVMe ports… Read more »

Hardware which are used in these devices are too good and reliable and the proficiency is beyond the mark.
