How to place a partition on different physical disks?

Question

linux

I want to place a partition on ssd and hdd at the same time, I want to place a root partition on ssd, but since it is small, I want to place part of it on hdd. The most logical thing that comes to mind is to create a partition on the ssd, create another partition on the hdd and link some folders from the hdd to the ssd. How can this be done smarter? And is it possible?
