From my personal experience, i trust more Seagate, other peoples says that WD is better. Now to justify why i prefer seagate, 9 years ago i had 2x500GB wd blue, one completly died (does nto show up on BIOS) and the other had bad sector, 4 years ago bought a computer at work 2x1TB wd blue, both of them developed bad sectors after 3 years, 2 years ago i got my self for my personal computer a 4TB WD black, developed bad sectors after 1.5 years. In the same personal computer i have a 10tb seagata hdd (Iron wolf) for 2 years now, 2x2tb barracuda for 5 years now and at work 2x500GB barracuda all of them in perfect condition. Either i m the most unlucky WD customer or in ym country they send bad quality products.
