At first, I chose this hard drive on the recommendation of a friend. View the price I thought it was crap :))) But thanks to the comments of the Amazon, my choice was justified. 1: The drive is very light (one might think that there is air lol). 2nd: Silencer (I know it's an SSD> This is my first experience) 3rd: fast ... Very fast W7 pro starts in 10 seconds. Here buy this hard drive will be for you an investment performance.
