Then there is also a Windows method with Intel's SSD Cache using a dedicated SSD as only a cache. Either way gives you a similar result.

Swap? Really? That is a waste of (expensive) disk space. There is no
point on having swap on SSD if you have another disk around. You
wouldn't notice any speed difference if your system starts swapping
you are in serious trouble (i.e everything crawls) the best fix here
is to just buy RAM which is *very* cheap now days.
