Bought this as a new back-up for movies, music, tv and books. I've been using a LaCie 4TB hard drive for my backups for the last three years or so, but I was getting worried it might be reaching the end of its lifespan. This wasn't for any particular reason, it's just that I've heard too many stories from friends about backups suddenly dying and everything being lost... The Seagate 8TB is fine so far. Tons of space and works smoothly and fast. Plus, I still have the LaCie in the cupboard with all the old stuff on it, so now I can sleep more easily at night, knowing I have two sources for backups!
