[opensuse] Leap on SSD

Hi all, I need your advice and help. I got a new laptop at my workplace, with the cheapest version of Win 10 pre-installed. It has a 16 GB SDD and a 1TB HDD. I would like to change it to Leap, and have my Win7 in a virtualbox. I have never used an SSD before. Is that 16 GB sufficient to to put / onto it, and have /home on HDD? What filesystems do you suggest? Thanks, Albert
