Short-listing these 3 external drives/enclosures for my Mac Mini HTPC storage Fantom G-drive Green 1tb OWC's Mercury Al-Elite 1tb drive Icy Dock 1394 enclosure + a WD 1tb Caviar Green (drive not linked - we all know what it is...) My desired criteria: must run relatively cool - it will be in a badly ventilated cupboard that can reach 100ºf at times. Not too noisy is a plus, as is low energy consumption. If one of these drives is capable of idling down when not in use then that would be a huge bonus. What does the MR crew think of these 3 choices? Your comments welcome.
