[Moderator note: 3/17 - moving thread from Networking to Storage (NAS). More applicable category.]

I'm trying both on my own built NAS's —both with different hardware. I like Proxmox for its ease of use and VM and container deployment. However, Truenas has a great GUI and allows easy installation within.
I find docker and other containers hard to install under Proxmox.
Ultimately, I would like one NAS to store all my data, documents etc.
Mobile phone photos and videos. (I have Immich on Truenas only).
Music collections
Thanks for any recommendations.

More of a Storage than Networking question. But Proxmox is a hypervisor and TrueNAS is a self-built NAS OS. You would have to install a virtual machine of a NAS OS into Proxmox, so you'd still have to compare TrueNAS to something else, and you'd be wasting resources running Proxmox just to run a NAS as a VM. (You could use PVE as a shared file server, but then it's just a SAMBA share with no NAS features, which you could just do with Linux or even Windows.)

Thx for your reply. I'm looking at consolidation oof both with a good backup. I like both. Maybe I don't have the knowledge to install Truenas on Proxmox. I found Truenas hard to install a VM? Or have I misunderstood?
So, do you think Proxmox is the best NAS?
 
No. Proxmox just isn't a NAS OS, period. Proxmox does nothing except host virtual machines/containers. You shouldn't even really think about Proxmox. If you just want a NAS, you need to be comparing NAS OSes like TrueNAS or Unraid or FreeNAS or the like (none of which I have experience with). You shouldn't waste resources and make things more complex by running Proxmox to host Immich and a NAS OS separately; just run Immich under the NAS OS like you said you currently do. You haven't described anything else that you want to do with it that would make it necessary or desirable to have Proxmox hosting anything.
