      I'm on Contabo's Cloud VPS L plan w/ NVME storage + their extra storage module (which doubles my 200GB to 400GB total NVME storage) and I ran the following command twice to test the disk speed and got 454 MB/s on my first run and 330 MB/s on my second run. This looks like regular SSD speeds, unless I'm mistaken and used the wrong command for NVME? A penny for your thoughts!

      dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync && rm -rf test

        You can also measure speeds with hdparm -t <dev> to get another data point.

          To figure out what my partitions looked like, a search led me to the following which listed all the partitions with their size and other info.

          sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL
          

          Then, I was able to use Nebulon's command

          hdparm -t /dev/sda3
          

          and the result is 416.88 MB/s

          @nebulon it looks like I need to get in touch with Contabo support, right? Unless there's something I can do to fix this?

          Edit: running some more tests..

          test drive cache read speed

          hdparm -T /dev/sda3

          OK, this looks like NVME speeds but what's the deal with the write!?

            @humptydumpty the cached read -T option is not very useful in this case. Surely helps to have that fast but it is just cached.
