How to stop Bitcoin core sync mid-sync

Hey all.

I accidentally started the bitcoin core sync without changing the download path to my SSD. I think, it’s downloading it onto the laptop, which does not have enough memory for the whole blockchain.

What should I do? Should I wait for it to reach memory limit? Can I even stop it at this point?

I was following this youtube video exactly, not realising I was about to start downloading it.

New to this, thanks for any help!
