My external hard drive (LaCie) have dropped taking me with him important documents, I had to quickly replace it. My choice fell on this 1TB hard drive. It is not possible to me to talk about his qualities as I use it only for a very short time. But I can already say that it is a small footprint for this memory capacity, as most existing drives. I put it in Time Machine and the entire hard drive of my computer it is saved daily. It is silent in operation. In short, it is now a supplement that suits me perfectly.
