Benefit of separating OS/Application drive from Media drive

I’m looking to purchase a new iMac 2017 5K with 1tb of ssd for 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 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? 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.

Please don't post the same thread in multiple areas. Having information scattered over multiple idential threads causes all kinds of confusion.

Separating the OS from your data on a separate partition (within the same drive) is the preferred way of operating with some OS' and the main benefit there is the ability to re-install or do whatever you want with the OS and not worry about having that adversely affect your data.

When your OS and data is on the same partition (traditionally how the storage is partitioned on Macs, with a single Macintosh HD partition) you lose that one benefit.

In your case, if you have an a 1TB SSD, thats using the PCIe interface (really fast, way faster than SATA, USB and TB) and you want to leverage that as much as possible to avoid long load times with large files. You can use a much larger and slower (potentially) external storage to hold your data for a longer period of time, but I wouldn't recommend working off it. You can transfer things back and forth as necessary to ensure that everything you need to work with is residing on the 1TB internal SSD.
