Hello all, I am looking to build my first server using Unraid and had a couple of questions before I start. I am coming from Synology and looking for the same reliability and use. The server is used mostly as a Plex server with Arr stack, Torrents, Audiobookshelf, and a few other things. The main question is how best to use Pools, cache, and the array. I have 8x14tb spinning rust, 2x1 TB NVMe, 3x2tb SSD. From what I have read, I am leaning towards this setup. The 8 spinning rust in 1 pool zfs2 (My understanding is ZFS can now be expanded). 2x1 NVMe in a pool ZFS RAID 1 (Docker Appdata VM, ext). Would this be a cache as well or just a normal pool? 3x2 SSD as XFS RAID 0 cache pool (temp downloads). Using mover to move the downloads to the main pool when over 80%. If I set it up this way, is there no need for an array? Is this the best way to set it up? Any advice or direction is greatly appreciated.

Sounds OK, you can use the NVMe pool as cache for one or more shares, though an 8-device HDD pool should already be pretty fast, unless you have more than 10GbE
