The cheapest in a brand known the day of my purchase! Ultra-fast installation. Computer backup software easy to install. Very quiet product. Set right beside my CPU, I can not hear the difference! A bit miffed to have seen flash sale 20 next week but good .. Finally, I regret the absence of switch for use only This external HDD only when needed. (Backups and movies in my case!) But I believe that SD with Inter. are a rare commodity.
