What about how to see we use an SSD not an HDD?

Hi guys!
Any commands for this or how can see it?
Thanks!

  • Dedicated server? smartctl -a /dev/sda

  • cat /sys/block/sda/queue/rotational

    Value: 1 = Hard Drive, Value: 0 = SSD

    That said I've seen VMs saying 1 when the host indeed use SSDs. It's a bit tricky with virtualization.

    There is also

    lsblk -d -o name,rota

    Same as above applies "Value: 1 = Hard Drive, Value: 0 = SSD" because it is actually just reading the file from the first method.

    You can try smartctl:

    smartctl -a /dev/xxx

    Look for something like "Rotation Rate: Solid State Device"
