if they use quality materials you will not have any problems… depends how lucky you are… i have a wd20ears with 4 platters and is running great since day one… was thinking of buying one with 3 platters and seen so many reviews about lemons in newegg and i gived up… My 4 platter hard drive is still stable with 3.5 years with only one bad sector
i have very old hard drives from twenty years ago and they are still running fine without any bad sectors and have several platters
