I can’t tell you the big smile I had on my face when I received this as a gift from my friend. He knew I was having space issues in my lappy and I desperately needed a HDD. Passport ultra was only better. And FASTER. The HDD is ultra light and no doubt ultra fast. easily gives 110-130 r/w. Now I can easily store all my BluRay edition movies in it without any hassle about the size or space. It has been nothing but a blessing to a nerd.:D
