I use a Synology 415+ NAS and keep the hard drives out of the room with my stereo. The NAS is populated with HGST drives. HGST drives have one of the lowest failure rate among high capacity hard drives. I have a Samsung solid state drive in my computer.
I am leaning more and more toward a network streamer and getting the (laptop) computer out of my music room.
I can't emphasize enough how important it is to back up your music. When I first started I ripped all my music to a Western Digital external hard drive. It died and I lost everything. I ended up re-ripping everything. I now not only have my NAS mirrored but I also have everything backed up off site.
