Is this a Retail drive with the Factory 5 year warranty, or is it an OEM drive that doesn't?

The product comes with a 5-year limited warranty, which suggests it is likely not an OEM drive.

The description says it's a 5-year warranty, but the Warranty & Returns tab says it's a 2-year. Which is correct?

The product has a 5-year limited warranty.
