I have very good experience with seagates. I have still one more than 10 years old 80 gb seagate hard drive, and it still runs good and fast. And I was formatting it like every week. My dad has 500 GB Seagate for 8 years, and still good and fast too. Oh, and WD BLACK is bit slower than Seagate Barracuda, that is 30 dollars less expensive.
