Hello Coronauts,

can someone please help me to understand, how much the process of rendering depends on hdd/ssd speed?

For my understanding, Corona uses the hdd mainly in the process of parsing the scene ? Except there is no more RAM than it swaps? Is this correct ?

So the parsing, in my case, is nothing that I worry about. But does a hdd slow down the whole rendering ?

I have most of my files except “project files” on external drives. I would invest in external ssd, if this would speed up the rendering.

Hope you all understand what I mean :-).

Thank you in advance
