Cache setup for TVS-874 w/ 2 NVME, primarily used for Plex

[ed]

If you create the very first volume on NVMe SSD, this will make Qnap store all apps and system files on this fast storage pool. This is much faster than caching. Normally caching is enabled to boost HDD RAID where SSD only volumes are too expensive. All multimedia files can be stored on HDDs. Plex will load from SSD and HDD will only serve as a source.

I hope this helps.
