Intel® SSD's (including OEM drives) are covered by Intel's Limited Warranties for Solid State Drives. The drives do not need to be registered in order to honor the warranty, however, we advise you to check the warranty documents for terms and conditions.
The warranty is only valid to the purchaser of the Product in its original sealed packaging (Original Purchaser) and to the Purchaser of a computer system built by an Original Purchaser containing the product (Original System Customer). Used drives are not covered by warranty.
Since you bought the drive brand new in the box, you should not have any problem with the warranty. It is recommended to keep the receipt or proof of purchase as it may be required for support.
