<![CDATA[VPS Disk Speed - Need Help.]]>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

Surely helps to have that fast but it is just cached.

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!?
