A NAS home build of this size will never exceed 10 Gbps, I barely get ~ 2 Gbps out of the spinning disks.
- walrus01 4y agothe main application where one will see real 10Gbps speeds is if the NAS also has a fast NVME SSD used for smaller file size needs at high speeds... for instance I have a setup which is meant for working with uncompressed raw yuv420 or yuv422p 1080p and 4K video, there's a 512GB NVME SSD and a 1TB SSD set up as individual JBOD and exposed to the network for video editing scratch file storage, and it will definitely saturate 10GbE. this is actually needlessly complicated, if/when I build a more powerful desktop pc again I'm just going to put the same work file space storage on a 2TB NVME SSD directly stuck into the motherboard.
- AdrianB1 4y agoVery valid point, but I don't know how fast you will hit the chipset speed limits; that NIC is connected to the chipset that is connected to the CPU via a 4x PCIe link and from there to the nVME with 4x PCIe link. In theory you have 4 or 8 GB/sec max bandwidth, but the CPU-chipset link is not dedicated. If you go for Threadripper the math is very different, you have lots of direct CPU connections for (multiple) NIC and multiple nVME.
