## What the models said for it

- "The Industry Standard: AWS S3 ... Best for: Deep ecosystem integration, complex security/compliance needs, and teams already built on AWS." (Gemini 3.5 Flash, Object storage)
- "For most mid-market B2B companies, AWS S3 is the safest choice due to its maturity, extensive feature set, and broad integration support." (Claude Haiku 4.5, Object storage)
- "Market leader with a full tier ladder from frequent access to archive... S3 is the default if you are already on AWS" (Muse Glimmer 30B, Object storage)
- "The pioneer and undisputed industry standard. It sets the baseline API (S3 API) that most other providers copy." (Gemini 3.5 Flash, Object storage)

## And against it

- "Avoid using their Standard S3 tiers if you are on a budget—their egress fees ($90+ per TB downloaded) will catch you off guard." (Gemini 3.5 Flash, Object storage)
- "AWS S3 Standard for small workloads: $0.023/GB + $0.09/GB egress adds up fast" (Kimi K2, Object storage)
- "Avoid for tight budgets: AWS S3, Azure Blob, or Google Cloud Storage" (Grok 4.20, Object storage)
- "Relying on public cloud object storage (AWS S3, Azure Blob, Google Cloud Storage) for primary backups or active workloads without accounting for API call fees" (Gemini 3.5 Flash, Enterprise storage)
