Summary: Had to up the size of my backups for my Macbook Pro after loading HD movies of a 3 week motorcycle thru thru Colorado, Wyoming and Montana. Had a 500GB LaCie drive for 17 months that worked perfectly and fast, so I purchased this one. So far so good.
Summary: I'm a photographer and I use multiple hard drives to back up large image files. The LaCie 2TB Porsche Design has been my choice of hard drive since it was launched. You don't need a separate power source for it - just plug the USB cord into your computer.
Summary: The problem with buying backup hard drives is they are not created equal and their inherent weak reliability seem to arise when you need them most. I bought my LaCie 1TB Porsche two years ago. I reformatted and partitioned the drive so it could backup both my Macbook pro and desktop mini.
Summary: Awful experience and I bought inside te Apple Store to replace my old one, by another brand, that still works. After just one year of use, it Crashed !! with 2.5 years of professional photos lost. Incredibly Sad! :( . Zero Stars is my rating.
