So, I currently have two Western Digital External HD's. One of them is hooked up to my iMac via FW800 and the other one is NAS so it's hooked via my router. The speeds on my NAS drive are CRAP and the FW800 drive is okay but could be much faster when streaming HD movies and working with audio files in my DAW. Now i'm looking for a Thunderbolt External Harddrive. Can someone who already has an External TB Drive guide me on which one to buy?
