How to deal with extra Gb?

Question

RAID

I have 3 screws for 1tb + ssd for OS
As far as I can remember, I have never used half of them ...
I want to put them into business somehow, so I think about the raid, I liked the 1E option, but I still don’t understand how to do it...
I watched this vidos , but I think he messed up at the most important moment there himself, but he didn't tell us....)))
Is there any point in 1E or make 0 and not hover your head!?
There are important data for me on my computer (after all, a working tool), but there are not so many of them, I think it can just take a place in the cloud by raid 0 or set up backups on a separate medium !?

You need to do what you need. And how you need - no one but you knows
