Bitcoin Node

I guys. I am installing my first BTC node using a Raspberry PI 4 And Umbrel OS. Everything very simple for the moment. Now I am downloading Blockchain am I have a doubt. I am using a SSD of only 500GB instead of suggested 1T. Do you think that’s enough? My idea is to start learning and eventually upgrade the system in the future. As you can see I am now at 16% of the Blockchain but using 130 GB (25% of the capacity) Thank you for your comments.
