Can definitely confirm this. I started with a Proxmox system which had a TrueNAS VM. TrueNAS just used a USB HDD for storage though. Setting everything up and getting the permissions set correctly so I could connect my computers was a pain in the ass though.
Later I bought a synology and it just works. Only thing I would recommend is getting good HDDs. I bought Toshiba MG08 16TB drives and while they work great, they are obnoxiously loud during read and write operations. They are so loud, that even though the NAS is in a separate room I have to shut it off at night.
Meanwhile the Seagate Ironwolf drive I used for TrueNAS was next to my bed for multiple months and was basically silent.
