Hello Co Ky, sorry to message you two years after, but I'm also thinking about replacing my hdd to ssd and maybe the cpu also. I have the same imac 2017 21.5" and already 16gb of ram installed.
Do you think it's worth the case to do these upgrade ? Or you did not noticed any differences ?
I'm also composing music mostly on Ableton and from times to times Logic pro, also web developping using Docker Desktop, Node JS, etc.
Thank you in advance,
Jonathan
