does rendering process depends on hdd/ssd speed?

[MicahMakenzie]

Hello
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.

The HD has an effect when Corona has to load assets (textures, proxies, etc.), and indeed when it runs out of RAM and has to page. In the first instance, the type of HD helps. In the second instance, any form of HD is so many orders of magnitude slower than RAM access that your render will be greatly slowed down anyway.
