I think have installed Centos on SSD but I'm not sure and I want to check this on my VPS. But I am not sure how?

There is no way to tell what drives are being used unless your on a bare metal dedicated server.

The best you can do is a benchmark on your disk IO and see how it compares to average HDD/SSD IO speed.

There are too many codes there and I don't know how to use them or if I run them on my VPS, it can be harmful to my vps disk

Would you please share me easy way to check?

Login to your VPS via SSH and run this command


dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync

As mentioned unless its a dedicated server. I can help you with checking however an easier way would be to contact your provider. They should get back to you with an answer.

I could not agree with you about this. Some hosting providers can hide what they knew if they are bad points on their servers. For me, I will want to check by myself.
Sad but true!

I do not see a reason for hiding if centos is installed or not.
That is not what the OP is asking. He wants to check if the VPS uses SSD vs HDD, not if CentOS is installed...
