The warranty terms PDF (an HGST document) on Amazon just directs you to hgst.com:
How long does limited warranty coverage last?
HGST Product warranties last for different periods of time. To determine the warranty period for
your specific Product, please visit http://www.hgst.com.
HGST's site recursively refers you to hgst.com.
NewEgg says it's 3 years, but I want it from the horse's mouth.
An aside: anyone thinks a 2 year warranty/128MB cache HDD is a better choice than 3 years/8MB?
