Since the wifi system I have does not have a USB port for network storage I have to buy a NAS pretty quickly.i narrowed it down to the Asustor as1002t, Synology ds216j and the WD MyCloud EX2 ultra. Between these which do you think would be the best choice? The WD is the most powerful hardware wise but I'm looking for the best overall experience. Quietness is important as I will be sitting next to whichever I get. Thanks for your input.
