So I have a NAS that I pop movies on and watch from. I have nearly filled up a 1.5 TB drive, and it seems rather worthless to replace that with a 2 TB... but that is as big as they come now. So where are we going next? 3 TB or 4 TB? And any idea how soon? Seems like we have been at 2 TB for a year now, should be time to change that upwards!
