You can buy "datacenter-grade" drives from WD on their website, which are presumably of higher quality. Either way, though, this is going to cost five figures, annually, to store in S3. For half of one year of S3 you can have a fairly robust RAID setup, maybe replace 1 drive every two years, and enjoy the data any time you want it without fees-as-a-service. High five for avoiding AWS!
