I am looking for recommendations about a home NAS.
1. The current situation: 2 Mac laptops, 2 iPhones, 1 iPad, no desktop; 1 TV with attached Apple TV (3rd gen) and Amazon FireStick; heavy photography interest, although current collection only runs ~240GB. Backups to a few small, portable, 1 and 2 GB drives, locally, not over network. Router is aging but still kicking Airport Extreme.
2. Goal: archiving/storage of photos and everything else (perhaps 3GB altogether).
3. If possible: access from outside home network; integration with Dropbox/Amazon Photos; photo sharing with family.
4: Possibilities considered so far: Seagate Personal Cloud; WD Cloud; Buffalo Linkstation; Synology. I note that Seagate and Synology include apps, including Wordpress installations that I could use for sharing photo albums with family.
At this time, I would like to put less than $300 US into the whole thing. Otherwise, I'll just stay with small external HDDs.
Thanks in advance!
