Good on ya, with that much storage I would do that too :P
I’m about to build my first NAS, and intend to start with 8TB - for family backups, photos, music, TV shows, and self-hosted apps. That’s why the thought of dedicating 3TB, or ~1/3 of my entire storage, to music alone sounds nuts in the eyes of a beginner like me😂
But I guess it’s true what they say: Storage grows with time! Although I don’t wanna know how many songs you’ll have when I catch up to your current number…
