The feature that separates Seagate’s GoFlex TV from the competition is its ability to harbor one of Seagate’s own 2.5-inch GoFlex portable SATA hard drives inside the device. What’s that, you say? All your portable hard drives use USB? Not to worry, as the GoFlex TV will host external USB drives, too, much like the media streamers from ViewSonic and Western Digital.If all you care about is getting your Netflix fix, Roku’s HD XR is your drug (if you can get over its 720p max resolution). The GoFlex TV will stream Netflix movies—and it offers 1080p resolution—but you’ll need to access your account on your PC and add movies to your Play Instantly queue, first. In that regard, it’s the weakest offering in this field. Beyond Netflix, however, Seagate’s box is much stronger than Roku’s: You can view or listen to a variety of content stored either on an external hard drive plugged directly into the GoFlex TV or on a PC, NAS box, or server on your network.
