Hey everyone, I own an older Windows 10 2018 build used for video editing. My system has an i9-7920X with 44 lanes and a Gigabyte x299 AORUS Ultra Gaming motherboard (see manual link). I connected it to my NAS via a 10Gb switch, but the throughput is only 180-200MB/s, far below what I expect for a 12TB RAID setup with -6. Other NAS units show similar speeds but at 2.5Gbps – still not reaching the full potential. Local USB downloads are blazing at 600MB/s (limited by the drive). I recently upgraded the switch to 10Gb, yet performance remains unchanged, suggesting the network card might be the issue or its PCIe bandwidth is capped. The motherboard lists it as connected at PCIe 3x4, but I can’t verify the actual speed. I suspect a limitation on the PCIe lanes – possibly only PCIe 3x4 speeds are supported, and all my peripherals are using the 24-chipset lane limit. My setup includes three M.2 drives (8 SATA HDDs) and a 1Mb SSD in the PCIe slot. The GeForce 1080 Ti is in one PCIe slot, but it’s blocked by the video card in another, so it can’t be used. If all three M.2 slots are filled, that would block further usage. I also have a USB hub connected to the back of the PC. Everything functions normally except for the 550T2 adapter, which is clearly underperforming. Could anyone confirm if I’ve exceeded my PCIe lane capacity or if there’s another bottleneck? Maybe swapping to an Intel 710 chipset could help, but I’m not ready to try yet. Any suggestions would be appreciated. Thanks!

Have you checked using tools like iperf to assess network performance? It might point to a problem with the NAS or its settings. What speed does the x550 currently have?

I haven't experimented with iperf3 because of my tech constraints. However, the local USB ports on NAS devices are significantly faster and more reliable at high speeds. I've already tested two Qnap switches (2.5/10Gbps) and the hardware info confirms I'm running 550T using a PCIe 3 x4 interface delivering 8 Gb/s. All the ports display 10Gbps performance.
