Best disk setup

Hi.

I just got a new laptop and want to set it up for video editing using Premiere pro & After Effects.

It has a SSD running Windows 10 and all the software. (C-drive)

Then It has a build in HHD 7200rpm. I Use that drive as Premiere Cache, and I'm rendering to that drive as well.

I use an external SSD with thunderbolt USB C 3.1 connection. On that I have my Premiere Project files and all the footage, audio and After Effects files.

But is that the best chain with what I have?

- or is there a better way to set it up?

Thanks
