Buying a NAS for a family cloud?

Hi, I don't know if you can help me. I'm in the US, thinking about constructing a family cloud. I have some experience with NAS (WD My Cloud paired with Sonos to listen to my music library), but am now thinking of something more ambitious. I'd like to put music, photos, and home videos on a NAS which can be read to and written to by family members around the country (roughly 4 or 5). I have probably 2 TB of content now, and it will of course grow. Currently I organize my music in iTunes and my photos in Picasa (notwithstanding the fact that it is no longer supported!). Of course, happy switch away from either iTunes or Picasa (PLEX? My son likes it).

Is this something that can be done at reasonable cost and with reasonable technical skill?

Thanks for any advice you can provide,
Peter Rathjens

If you want to keep the costs down, I would recommend Synology and their own apps. They have managed to create their software to perform much better around the given hardware compared to this party apps like Plex. You can use Plex locally, but for remote access, I would recommend first-party apps only. You can also keep on using iTunes if you wish so.I would recommend multimedia friendly models such as DS220+/720+ or more future proof options like DS420+/ DS920+. These models feature graphics chip which allows you to access multimedia remotely.I hope this helps.
