Hi,

Before checking for ssd, you have to check on which device your root is located, please run below command, to check your device on which root located.

*******************
df -h
*******************

but it will not provide you enough information, for more information you can use below command.

**********************************
lshw -short -C disk
**********************************

At my end the device was showing as /dev/sda, now let's check the "Rotation Rate" for the same device using below command.

********************************************************************
smartctl -a /dev/sda | grep 'Rotation Rate'
********************************************************************

If your device is on SSD, then Rotation Rate will show as below:

********************************************************************
Rotation Rate: Solid State Device
********************************************************************

Is there any way to check if the VPS disk is SSD or not?
There are many ways to check this, but the important point here is that many VPS providers do throttle disk performance, so you not overuse it. Having 50MBps on SSD is not much solace.

Just check if the disk is rotational by using command:
$ cat /sys/block/sda/queue/rotational

If it returns with 1, disk is HDD and if output is zero, disk is SSD.
