Hey folks, I'm in desperate need of an external hard drive to store my movies/music on, and plan on picking one up today. Can someone let me know whether it would be a better idea to purchase a Thunderbolt external hard drive or a USB 3 one? What are the pros and cons of each? I have an rMBP, and as such, have 2 TBP and 2 USB3 ports. One of my TBP is usually occupied by a TBP/ethernet adapter. Thanks for any thoughts!
