I am always satisfied after almost a year of use. Different brands or models within the same manufacturer, you can fall on hard drives can be very slow and noisy at best. It is very fast read / write enabling even gymnastic rotating two parallel disks by placing the swap file and TEMP on Western Digital while keeping the rest of the OS on the original disk . This relieves the machine and you do not feel the difference if a slight improvement of capacity. Question noise, it is very discreet, even more than the first record that I use and that covers the sound of WD. A advisor.
