My 2TB Seagate USB 2.0 recently died and I want to replace it with a high quality 3TB or 4TB external disk. It does not need to be portable. It is for use with my 2011 MacBook Pro at a desk environment. I need it primary as a Time Machine backup as well as general media storage. It needs to be reliable as it will be used for my college work and audio production. I am torn between spending extra for Thunderbolt or spending less and using Firewire 800. Firewire is much cheaper and I have the available port, but I've seen Thunderbolt in action and the speeds are amazing. However, my Apple Cinema Display connects to my MBP's Thunderbolt slot, so any Thunderbolt drive will have to have two Thunderbolt ports for daisy chaining. Anybody got some tips or advise for what to go for?
