Hello, I just took a Western Digital Scorpio Black out of a laptop I had laying around and put it into my PC. It is the same size as an Solid State Drive and I am wondering if it basically is an SSD? I have a main Western Digital Blue Hard Drive in my system right now as my main storage but I am wondering if I could move my operating system to the Western Digital Scorpio Black and if it would boot it up faster? Its 320gb so I might put some games on it too that I play a lot if it works as an SSD. If anyone could help out I would appreciate it. Thanks.
