Seagate was the only company that offered a 5 year warranty. They stopped that practice during the flood, just like everyone else though. Now all the companies only offer a 1 year warranty.
The last time I bought a WD Red, it had a 3-year warranty. No idea if that has any meaning these days (especially if you put it in a machine you build rather than a consumer NAS... I suspect their response would be "sorry, you didn't use it according to our spec".)
