Just this last May, my hard drive crashed and I lost about 500 gigabytes of data. That was my old Hitachi drive that came with my computer when I bought it. It lasted less than 2 years and crashed suddenly, much to my disappointment. I bought this to replace it, having heard many good things about the Raptor and of Western Digital in general, and I have to say, I am beyond satisfied with its performance. It is very fast and I never have BSODs anymore. All in all, a great product. Highly recommended.
