How to know if my server storage is NVMe or not?

Hello.

I recently bought a server from somewhere and it mentioned having NVMe storage.

Today I was just curious if it had or not, and I found this command that lists storage devices:

lsblk -d

The results returned:

NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sr0 11:0 1 1024M 0 rom
vda 252:0 0 80G 0 disk

After some searches it looks like they are CD/ROM etc. I'm unsure what to conclude.

    If it's a VPS I don't think you are able to tell. One of your partitions named vda suggests this.

    Maybe try running an IO benchmark. If it's fast enough it's probably NVMe.

    This. Also disk model will probably be something like "Virtual disk" when using VPS.

    Understood, thank you. I've never ran benchmarks on a server before. I'm looking up online for some guidance. Do you have any resources to share?

    Why do you doubt your provider?

    Are you running into disk I/O bottlenecks or something?

    https://romanrm.net/dd-benchmark. I use this one quite often. The recommended option with the fdatasync. You can adjust the value of count to a higher one, but make sure you have enough free disk space. count=256 & bs=1M = 256 x 1MiB = 256 MiB (iirc the value is in MiB but don't pin me on that).
    count=10240 & bs=1M = 10240 x 1 MiB = 10240 MiB = about 10 gigabytes, etc.
