Todd,
Try dropbox 1st. If it is fast enough, run with it. I do run a synology ds412+. This runs as a personal (company) version of dropbox. It updates super fast on local network. Netgear wireless router r6250. It connects at 234 Mbps wireless. That is about 1.8gb per minute if my lookup is correct. Outside the office depents on you internet speed. We run 50 download / 12 upload. More on cloud staion HERE
