It worked well with the 1TB external and the total cost (again, I had the drives already) was 150.00. NAS was already on the system so going from one to the other was $0 and the externals will be for data/photo and misc that did reside on the NAS.
JRiver works well as I have it on my desktop/laptop/tablet and can control fram any and all. Still working out everything as far as the software end, but running over a wired network was the best for me, wince I already had a CAT6 going to my Magnum Dynalab MD807 and the tv mounted behind and above the stereo rack, a 49.00 gig switch and a couple of CAT6 jumpers and everything is on the network. With the snow this weekend I hope to have plenty of time to now enjoy the music, much of which I have listened to in years and maybe even get a chance to build playlists....
