I have a WD Live connected via a USB to a 2 TB drive. I want to replace this drive with a 6 TB My Book Live Duo, connected to the network cable. Those of you who have this set up, does it perform well? With 10 GB 1080 files? And most importantly, can you see the icon thumbnails for each movie title? My reason for concern is my son set up a network server using an old computer for me, which played movies fine, but you could not see the icons.
