I personally think if you spend the money on a Synology setup and you depend on this script, you’re playing with fire. If you intend to keep DSM updated, you run the risk of Synology playing a cat-and-mouse game that doesn’t end well. Sure you can do this now, but forever? Who knows how long it will last.

Also https://github.com/007revad/Synology_M2_volume for NVMe M.2 drives (some synology models only allow NVMe drives to be used as read/write caches without this script)

Yes but the worry is that they might get rid of this eventually
