It would be nice if you could set a folder in Plex to act as a disk cache.
This would allow content to be duplicated onto the cache disk based on the rule that is setup (recently aired, recently added etc) similar to Optimised Versions and Sync, however this wouldn’t show in the library as multiple versions and a client wouldn’t get the option of selecting the NAS version, it would automatically choose the cached version.
This would help prolong disk lifetime in NAS devices and reduce power consumption by allowing multidisk NAS boxes to be spun down more often. It could also improve performance especially if the cache disk is an internal SSD, more streams can be handled especially if the users NAS is an inexpensive and slow model.
This would be similar to the Optimised Versions and Sync in it’s setup or could be combined in one of those functions instead, the only difference is that the client wouldn’t get the choice of where the file came from, the cached version would always be preferred over the uncached one.
I realise that something like this can be setup on the underlying operating system with tiered storage, however this can be quite a complicated and possibly expensive process and unsuitable for many end users to implement. It is also very different to implement on different operating systems.
Thanks for reading, hope you think this is a good idea.

Matt

Also being able to have recently added placed on SSD. I know it may not be needed for most people but I for one hate having to wait for my drives to spin up.
