I hesitantly purchased this hard drive after the one that originally came with my MacBook Pro failed. As with most people I put a lot of research in to selecting the perfect hard drive for my needs. I narrowed the list down to three and in the end settled for this drive due to the numerous negative reviews for the other two. After ordering the drive I found some more reviews that mentioned how in a MacBook pro this drive was noisy and would cause annoying vibrations.
You should definitely not trust all the reviews you read on the internet. This drive is definitely noisier than my old hitachi drive but not noticeably so, especially when you have some background noise or the fans up a bit higher. When I read other reviews I thought that this hard drive may have been significantly more noisy but that is definitely not the case. It is perfectly acceptable for a faster replacement drive. As for the vibrations, you can only feel them when you try and concentrate on them. Even then they are very very weak. Not even noticeable.
I was not too impressed by the packaging however. It came (with a cable that I had ordered) in a large box full of brown paper. Within that large box was a smaller box that contained the hard drive. The drive was supposed to be suspended between two plastic supports however when I opened the box I found it to be on the bottom of the box instead of in those supports. The hard drive works perfectly well however I do feel that it could have easily arrived damaged.
This is a great hard drive and I would definitely recommend it to anyone looking for a faster, larger hard drive or even as a replacement for one of very similar specs.
