Amazon Drive (Amazon Photos)

Amazon Drive, now primarily focused as Amazon Photos, offers unlimited full-resolution photo and 5GB video storage for Prime members. General file storage is limited. Its security leverages Amazon Web Services' (AWS) robust infrastructure, including encryption and compliance certifications. For advanced users, integration with AWS S3 (with Object Lock for immutability) offers enterprise-grade security options, but with more complexity.

It ranks as a good option due to its exceptional value for Prime members, the underlying security of AWS, and its strength as a dedicated, secure photo and video archive.
