They’ve done this before. 5 - 3 - 5 - 3, when they lose some more market share over it, and someone else offers 5 years on similar product, they’ll bounce up to 5 again. Or they’ll offer 5 on specific drives, which will of course cost more, and 3 on the rest. Nothing new really. Typical games drive makers play. WD does they same stuff. If you really want or need a 5 year warranty, just look around, there’ll be drives that have it.
