How Our Cloud Storage Comparison Works
Our cloud storage comparison calculator analyzes pricing from the five major cloud storage providers: AWS S3, Azure Blob Storage, Google Cloud Storage, Backblaze B2, and Wasabi. The calculator factors in both storage capacity costs and data transfer (egress) fees to provide accurate total cost comparisons based on your specific usage patterns.
Storage Cost Components
Choosing the Right Cloud Storage Provider
The optimal cloud storage provider depends on your specific use case. For backup and archival with minimal data retrieval, Backblaze B2 or Wasabi offer 70-75% cost savings compared to AWS S3. For applications requiring frequent access and high bandwidth, consider data transfer costs carefully as egress fees can exceed storage costs. If you're already using a cloud platform ecosystem, staying with the same provider often provides better integration and potential volume discounts.
- Wasabi and Backblaze B2 are cheapest for pure storage with low to moderate transfer
- Azure Blob offers best balance of features and competitive pricing
- AWS S3 has most features and integrations but higher baseline costs
- GCP Cloud Storage excels for analytics and ML workloads despite higher egress costs
- Consider CDN integration to reduce egress costs for content delivery
- Use appropriate storage tiers (hot, cool, archive) to optimize costs based on access patterns

Requirements:
- Storage: 10,000 GB (10TB)
- Transfer: 5,000 GB (5TB) monthly
- Tier: Standard (frequent access)
- Use Case: Video streaming platform
Monthly Cost Comparison:
Recommendation: Wasabi or Backblaze B2
For this use case, Wasabi offers the best value at $59/month ($708/year), saving $621/month compared to AWS S3. Backblaze B2 is also excellent at $110/month. However, consider using a CDN (CloudFlare, CloudFront) to reduce direct storage egress and improve streaming performance.
Backup & Archive Example
50TB backup storage, minimal retrieval (100GB/month)
Best: Backblaze B2 - $301/month vs AWS Glacier $231/month (but retrieval costs add up)
Website Assets Example
500GB storage, 2TB monthly CDN transfer
Best: Use any storage + CloudFlare CDN (free 1st TB) = ~$15/month total
