Adriana has a Synology DS1520+ NAS, and she's upgrading to a new model soon. She's then planning on putting the latest release candidate DSM 7.0 onto her current model. She then plans on using the NAS to back up her photographer husband's photo archive. What is the best way to connect a universal power supply to the NAS? And which one? Leo says that Tripp Lite is very good, as is CyberPower CP800AVR which Leo uses. And they aren't that expensive either. Leo's was $100.
