Adding another SSD to Qubes OS

Good evening everyone,
So you have added a new 250Gb SSD to my cube system. The main Qubes-OS on 1 SSD the other SSD used for saving docs,vids,images…etc/ backing up Qubes. My partition it in 2 each 125Gb. I reading the docs I don’t see anything about adding another drive to the Qubes-OS.

Is there anything specific or special I have to do to protect this new SSD I have added to Qubes? So it’s not infected/hacked or whatever?

It will be a internal install of the SSD not using external USB

Thank you all for your time
