I have three drives in my system, all pcie-gen 4 NVME. The first is my boot drive, it's a 4TB NVME drive.
The second is a crazy-fast NVME RAID-0 that's 6 TB. This is where I keep the source footage and project files for the project I'm working on.
The third is a 1 TB NVME drive.
I've read various ideas about storage configuration and where to set your media cache for Premiere. Some people suggest keeping your media cache on a different drive than your project files. That's how I currently have it set up, media cache is on my third (1TB) drive. But the RAID-0 is literally 3x faster than that drive (it's made of a 4tb, 1tb and 1tb nvme).
Would there be any benefit to moving the media cache to the RAID instead of the non-raided drive?
All the options should work OK and the RAID should be your best bet but then again it might not. I have seen SSD RAID setups perform worse than my setup with 5 SATA hard drives. I have heard some AMD motherboards can be gltichy with M.2 SSD but a BIOS update can usually fix it. You will have to test things out for yourself. Can you do a read and write video with your RAID setup? One single drive and then the RAID setup like my video below? I am curious what speeds you get.
