I want to have my music on always ready SSD storage, while keeping my movies on slow moving ssd spinning disks. I don't want to wait for spinups should I add new music files. Is this possible?

It was possible, I believe, in the older unRaid version before the primary/secondary storage change to configuration. Back then I think I could just manually move folder to cache, 'disable' split-levels and tell it never to use cache ('prefer: no', or something)

When using primary/secondary storage, then new files will always be written to primary storage (ie. cache). I kind of prefer not to have that, but the worse part is that I cannot disable mover in this setting, and thus my files get moved back to disks by mover.

If I use primary=array, and no secondary storage, new files will be added to array, which I don't want.

The only solution I found for now is to create a separate ssd share on my cache drive with cache only storage (primary), and then moves files here and create links from original share. This works, but isn't really super UnRaid niceness. I really like unRaid's /mnt/user that gives me a shared perspective of where files are, and then my /mnt/disk*, /mnt/cache which shows me what files are there, and where files are the expected locations with the only question being which disk contains the files, not where they are linked from.

Is this on the potential future feature-list? I saw some mover improvements here, though I don't know what those were: 

 

The settings have not changed - just the nomenclature used to described them in the GUI and online documentation.

well, be that as it may, is it possible?

As long as music is a share, settings are per share.
