If you want an evaluation of your computer system I have a Premiere Pro Benchmark (PPBM) that will allow us to see how well your current system is performing and balanced. It is a little dated but it does have a CPU intensive test, a Disk intensive test and two GPU intensive tests.
Submit the results via the benchmark process and you also could post the results from the Output.csv here, it will look something like this: "76","194","56","802", Premiere Version:, 10.4.0.30 (from my several year-old laptop).
i have not bought the PCIE NVME drives, so afraid it won't help me. Also, i'm seeking feedback on real-life performance in Premiere Pro CC.
Should be no difference. That Sony codec is CPU-intensive, not disk-intensive. You'd still need to make proxies
