The Intel® SSD 530 Series have a 5 year limited warranty, that is valid for the original purchaser for a period of five (5) years beginning on the date the Product was purchased in its original sealed packaging in the case of an Original Purchaser, or the date of original purchase of a computer system containing the Product in the case of an Original System Customer invoice.
Please take into consideration that this does not apply to "used" drives, as they are not bought in the "original sealed package".

The 530 series was released on 2013, so these SSDs should still be covered by the 5 year limited warranty.
