SSD caching will unlikely help unless you run virtual machines/ web server or have many users accessing similar data.DS920+ supports 4K. I would even recommend running RAID5 on 3 disks and keep 1 disk separate for surveillance which can be connected also to a separate LAN. This would improve performance. Having 4GB RAM should be sufficient, but you can always add more RAM at a later stage if you decide to run more apps including Plex.I hope this helps.
