Webb6 maj 2024 · Summary of real write speed in MiB/s. NVME: 865 SSD: 309 HDD: 159 So the conclusion is that the write speed to the NVME and SSD drives is way lower than the theoretical one. We must conclude that there can be several bottlenecks that limit the speed, not only the device itself. I would not blame dd, I think there are other bottlenecks. Webb16 jan. 2024 · Seems possible that this is a real issue, but where are the big headlines about Intel's consumer chipsets and PCI-E 3.0 x4 NVMe slowdown, due to the fact that Intel platforms DON'T have a...
