DVD discs is not good for long term storage. it can get scratch and became unusable. you want a NAS/PC then rip the dvd and use plex or Jellyfin to watch your collection.
Unlike hard disks, they're practically immune to shock (e.g. being dropped). Unlike SSDs and unlike hard disks, they're immune to ESD. And even if you somehow manage to damage one, it's just one, not your whole collection.
