I think having huge NVMe drives for storing footage you are working on is overkill. You will almost never have benefits of it in real life (not everyone copying uncompressed footage from one drive to another while doing multi-cam editing).
So you'd better invest in bigger SSD drives from good manufacturer for these storage and have NVMe as your system/temp drive.
Probably the one exception is -- you use uncompressed a lot.
Or you use a lot of cameras at once that record in high bitrates, like prores.
I say have the best of both worlds.... tons of mechanical storage, a 2TB NVME for projects currently being edited, and a separate NVME for the system.
Anyone using hard drive docking stations?
Put a dual sata plug bay in my builds mostly for archiving. Used to use 2.5 inch laptop physical drives but switched to sata ssds. Was using T3 and T5's via usb3 for a while but have given up on them because they're more expensive and lower performance. Also using the sata plug bay for the sata ssd's that plug into the NinjaV recorder/monitor which I use to record ProResRaw over hdmi.

Just don't try using nvme m.2 to record ProRes... nvme sustained write speeds are not fast enough to avoid frame drops. While high quality sata m.2 (Samsung 860 m.2 EVO) and 2.5" ssds (SanDisk Ultra 3D) are golden.

Did you mean capture, not copy so to prevent frame drops?
Samsung 870 QVO (that is twice cheaper that similar size Samsung NVMe and available in up to 8TB models) will be able to handle only about seven 500 Mbit/s ProRes streams or single 4424 Mbit/s stream.
So if you do this on everyday basis, you probably need something faster (I bet, you knew that already).
However, from my point of view for majority of editors this is not a typical job.
What is a typical job for editors of technically demanding high end projects will become the typical job of tomorrow's average editors, within 5 years or so, so i'd say best to be ready for it considering that's the typical upgrade life cycle.
