I plan to buy Synology 214play to store all my pictures and video at home network and access it when travelling via 10/2mbit ADSL modem I have at home. What kind of performance in picture viewing, audio video playing should I expect via this relatively slow connection? I think I can back up stuff from the phone back to NAS pretty fast over 10Mbit. What about viewing the stuff over 2mbit. Is it painful and too slow?
