Storage Config Advice for PP and AE Workstation.

I'm redoing the storage in my workstation PC and could use some advice on how best to utilize my resources.

I have:

- m.2 NVMe SSD 250GB

- 2x 250GB WD BLUE SATAIII SSDs in RAID0

- 4x 1TB 7200RPM HDDs in RAID10

My current plan is:

- m.2 for my OS and pprogram

- SSD RAID0 for scratch/cache and current project source files

- HDD RAID10 for cold storage of completed projects.

I keep hearing that you can see big performance gains by having your media cache/scratch folder off your OS drive, but I can't see how that remains true on an NVMe SSD capable of 3GB/s - 1.5GB/s read-write speeds .

I could break up the SSD RAID and use one SSD for cache/scratch, one for current project source, use the m.2 for OS, and the HDD RAID10 for cold storage. But, I'm not sure which is more beneficial for PP and AE to see in terms of performance: individually addressable dedicated drives or raw IOPS performance? The nature of how SSDs pull data from flash memory makes me lean toward the latter.
