VPS Disk Speed - Need Help.

[humptydumpty]

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.
