    For me, I only got to 5 Gbps or so on my NVMe using dd and fine tuning bs=. In second place there was steam with ~3 Gbps. The same thing with my 1 Gbps USB Stick. Even though the time I saved by more speed is more than made up by the time it took me to fine tune.

      Sorry for the nitpick, but you probably mean GB/s (or GiB/s, but I won’t go there). Gbps is gigabits per second, not gigabytes per second.
      Since both are used in different contexts yet they differ by about a factor of 8, not confusing the two is useful.

        I think it is gigabits per second, but to be clear: Whatever dd reports as speed after finishing (or with status=progress)

          That’s in bytes. A modern NVMe drive can do about 7 GB/s (more than 10 for PCIe 5.0 drives). Even SATA could handle 5 Gbit/s, though barely.

            Yup, my PCIe NVMe should be readable at 8 GB/s and writeable at 7 GB/s afaik. I can’t reach that speed tho, no matter which bs.
