Trying to add a 2nd SSD to HA for frigate recordings. Is that possible?

I am running my HA and Frigate on a Dell CFC5C OptiPlex 3050 Micro Form Factor Desktop Computer, with a startup drive NVMe 256GB.

I want to add a Crucial MX500 1TB SATA 2.5 Inch Internal SSD, so I can write all Frigate recording and clips to this new hard drive.

Is that possible?

This is what I have done so far. Formatted the Crucial MX500 and placed it in OptiPlex. Crucial MX500 is “sda” and “sda1”.

I can see the following:

HAOS does not allow me to perform certain Linux commands.

How can I create a mountpoints? I would appreciate a guidance.
