Brought new hard drive, need advice.

I hope this is the right place to write this.

Basically I've been reading online that you can have your database/thumbnails on SSD and your raw media on HDD. I would like to have some support and advice regarding this.
I've done some reading but I'm kind of hesitant, and don't really trust myself to get it right if I were to move things around without some guidance TT

Thank you in advance!
