I have a Synology DS414+ and the CPU is showing its age. I currently have 5 cameras running with Surveillance Station and use my Synology for backups and it also houses my video library.
I am looking to upgrade to a new NAS and was originally looking at the DS920+, then started looking at some of the 2021 models. I saw the NASCompares review on the new DS1621 with AMD processor. I'm glad that I saw it before pulling the trigger, as it was mentioned that the AMD processor wouldn't be able to do the decoding for Plex, which I would like my NAS to be able to handle, although realistically I will probably end up using Apple TV or a Nvidia Shield instead. The DS1621xs is price prohibitive but has a Xeon processor, which would be great vs the Celeron in every other new model.
I will need the new NAS to continue running the same number of cameras through Surveillance Station. I also want to seamlessly stream 4k video through Plex, but it's seeming less realistic the more I look into this. I do not want a rack mount unit and would like to stick with Synology. I wouldn't mind having the flexibility of running a VM or 2 also.
