Warranty
WD currently sells many hard drives with a warranty of one, two, three or five years included in the retail price, but it offers the customer the option of purchasing a longer (two- or three-year) warranty on its web site. Three years is the current industry standard and while Seagate Technology (a competitor) used to offer a 5-year of warranty for all its drives, it recently moved back to a three-year warranty for its bulk (bare/OEM) consumer-level drives.
High performance Raptor drives as well as the Caviar Black Series and RE Series still come with a five-year warranty.
