I’m looking to purchase a new iMac 2017 5K with 1tb of ssd for 4K video editing. Because the source files of the projects I will be working on will be below 500gb for any given project, I would like to utilize the fast internal nvme as an active media drive AND OS/Application drive (I will offload projects to external backup drives when finished). I’ve read that keeping these separate is recommended but with such a fast internal drive I’m wondering if anyone can show or explain to me the real world benefits of separating. Will I really notice a difference if I keep both the OS/Applications on the same drive as my project files/media rather than separating? I will be editing on Premiere Pro CC with light After Effects. I will also be using an external Samsung T5 for scratch/media cache.
