The problem you are trying to address, cannot be solved by currently available data: You want the latest, the largest capacity and the most reliable drive you can get your hands on: - There is no reliability data available for these drives until maybe year or two later - at which point you will know whether your drive works or not. - You are focusing on drives with extended warranty - which is rational at first look - but all that that guarantees you - is the drive replacement, not your data. - If you think that warranty length correlates to failure rate, that is not necessarily the case - what you are actually buying is drive replacement promise. - If you have two identical size drives for identical price with different warranty - the longer warranty drive must be more reliable to be equally profitable. - If you buy identical size drive with 2x longer warranty at 3x the price - the reliability can be equal or only marginally better to achieve higher profits. Depending on how easy/cheap you make the replacement/shipping process. If you want to maximize/guarantee data reliability for given $$$ - the sweet spot is mainstream, good price, known reliability drives in redundant setup such as RAID/ZFS/Btrfs/HDFS/..., typically accessed over network. This way you can chose your reliability/size/speed/$$$ ratio and you can share the storage between all your computers too, minimizing the cost per computer and decoupling the storage from computers.
