I'm migrating off a self-managed store to unRAID because, well... I'm tired of maintaining it. However, I am totally lost as to how the storage management works--and yes, I have [read through the documentation](https://docs.unraid.net/unraid-os/manual/storage-management/).
Basically, what do I do when I have vastly different storage disks? For example, right now I have:
* 128G flash drive that unRAID lives on (Samsung Bar Plus)
* 1TB m2 NVME which has historically been where the operating system resides
* 1TB 2.5" SSD (store thumbnails and other stuff for Immich for fast access)
* 2x 2TB 5400RPM , zfs mirrored (photos using Immich)
* 2TB 5400RPM (frigate clips)
* 2x 14TB EXOs X16s, zfs mirrored (movies, TV shows, etc.)
When I initially set this up, I basically modeled it like I would a normal system. However, I'm realizing that this is the "wrong" way of doing this as I have no "array" disks specified so everything is basically a cache.
What's the right way to model storage when there are significantly differences in capacity?
