I need help on deciding on whether I should buy Thunderbolt or Firewire 800 external hard drive. I plan on buying a 6 TB hd soon to store my iTunes library on. My library is a little bit bigger than 1 TB and growing. I have over 10,000 pictures i also want to back up, and I want to download all my videos I have on my video camera and store them all in one place. Right now I have 550Gb left from my 2TB HD on my iMac. I'm going to configure it to RAID 1 Should I go Thunderbolt because of the speed and because it's the newer technology? Or should I go Firewire because its cheaper and once I get everything over to the external speed won't matter.
