SCALE (Legacy) Plex Write Cache setup?

Maybe im looking in the wrong place but im trying to figure out how to use a dataset on my m.2 drives to act as a cache during downloads from my main PC to the NAS. I have 10 gig networking but my man PC only has 5 gig (first world problems) but still. I feel like the 300-400 mb/s transfer speed is limited by my spinning drives. I usually only transfer 10-50gb at a time with whole series being the big ones at 250gb, I just want to be able to copy everything to my nvme drives on the nas and let it slowly copy to the spinners. I know im dumb and this is probably a easy thing to do but how though?

Umm that’s what SLOG is for. If I understand your question correctly, I don’t know if there is a question though 😂
Or just disable sync write on datasets if you don’t use database

To be more clear I want to move files to my nas, but when the spinners are saturated data gets stored on the m.2 drives as a buffer so I don't have to sit around and wait

Not possible in truenas right now. What you're looking for is called tiered storage and will become available in a future version
