Contabo S3-Compatible Object Storage Review (2026): Performance & Pricing Test

The Expensive Reality of Hyperscaler Object Storage

Amazon S3, Google Cloud Storage, and Microsoft Azure Blob charge intricate pricing models: you pay per gigabyte stored, per 1,000 PUT/POST requests, per 10,000 GET requests, and worst of all, exorbitant egress fees ($0.09 per GB) whenever your users download their files. Contabo Object Storage eliminates complex billing matrices by offering predictable, flat-rate S3-compatible storage starting at just $2.99 per month for 250 GB with completely free data egress.
