SATA SSD vs NVME M.2 SSD in Blender

Hi, I have a question regarding Nvme ssd performance for blender.

I have two 1tb ssds. An nvme and a sata.

I installed Windows on my Nvme Ssd M.2 ssd and my programs as well. Which setup will give me the best performance? I read in an article on cgdirector, that Blender performed best, when the project files are on the nvme but windows and blender itself are on the normal sata ssd. Should I reinstall windows to the sata or can I keep everything the way it is?

Thanks very much.

The performance difference will be marginal. It's usually better to have the OS and Programs on the slower drive and your project files (that usually take up more room) on the fastest drive though.

This is especially true for Video Editing when you're working with huge footage files. Depending on your scenes (large textures, caches?) the nvme might get you slightly better performance.

So on my Dark hero I have 2 x M.2 slots. The one nearer to the CPU has the direct link to the CPU, I assume that will be the Windows boot drive. I am about to order 2 M.2 drives. Shall I pony up for two PCI Gen 4 or is Gen 3 good enough for our line of work?

This depends a bit on what you mainly use Blender for. If you're also doing Video Editing or Compositing in Blender, the pcie4 discs might get you slightly higher performance if you work with heavy footage. For Modeling, Rendering, pcie3 will be more than enough.
