Very quiet and good performance HDD previously had bought Seagate which used to make lot of noise. This one is silent and good. Only thing to note is that only in 1 TB you get 7200 rpm in higher storage (2 TB and above) it is only 5400 rpm. The 7200 rpm performs nearly 30% faster than 5400 rpm one but it depends on your personal choice. As far as the WD hard disk is concerned have used it for the first time and have become a fan of it. I would highly recommend this as this is the most dependable HDD out there in the market.
