Hello , I will be most likely buying a macbook pro (probably with 256gb storage) in the very near future, and because my dissertation involves large amounts of video recording (and needs to be backed up!!!), I will need to buy a portable external hard drive. Initially, I was looking at the Lacie Rugged Thunderbold 1TB HDD hard drive (http://www.amazon.com/LaCie-Rugged-...3280&sr=8-1&keywords=lacie+rugged+thunderbolt). Is this a good value? Or should I just go with a cheaper USB 3.0 hard drive (since I am going with a HDD hard drive, would the speed difference between Thunderbolt and USB 3.0 be really that big?) I know that SSDs are the fastest, but they are also very expensive and I don't think I could afford one that is more than 120gb (and I need more than that)! I would appreciate some of your thoughts on what would be the best hard drive for me to buy value-wise (will need at least 500gb of storage, but more is better). Thank you!
