Cloud Storage Pricing 2026: Complete Provider Comparison
Cloud storage pricing has changed dramatically in 2026. What used to be a simple choice between AWS S3 and a few alternatives is now a fragmented market with providers competing on price, performance, and API compatibility. For AI teams, developers, and startups, picking the right storage provider can mean the difference between a manageable infrastructure bill and a surprise invoice at the end of the month.
This guide compares the major cloud storage providers head-to-head: AWS S3, Backblaze B2, Wasabi, Cloudflare R2, and BHK Cloud. We break down storage pricing per TB, request fees, egress costs, and the hidden charges that most comparisons skip.
Why Cloud Storage Pricing Is Hard to Compare
Every provider advertises a simple per-GB rate, but the actual cost includes several dimensions that most buyers discover too late:
- Storage cost — the base per-GB or per-TB monthly rate
- API request fees — charges for PUT, GET, LIST, and DELETE operations
- Egress fees — data transfer out to the internet or between regions
- Minimum storage duration — some tiers charge you even if you delete early
- Minimum object size — small files may be billed as if they are larger
- Retrieval fees — cold storage tiers charge to access your own data
A provider that looks 30% cheaper on storage can cost 2x more when you factor in egress and API usage. This is especially true for AI workloads where data moves frequently between storage and compute.
Provider-by-Provider Breakdown
AWS S3
AWS S3 remains the market leader with the most mature ecosystem. But its pricing model is the most complex in the industry. The base rate of $0.023/GB (approximately $23.55/TB) for S3 Standard is just the starting point.
What AWS S3 costs in practice:
| Cost Component | Rate | Impact on 10 TB/month |
|---|---|---|
| Storage (S3 Standard) | $0.023/GB | $235.50 |
| PUT requests | $0.005 per 1,000 | $5-50 depending on volume |
| GET requests | $0.0004 per 1,000 | $4-40 depending on volume |
| Data egress (internet) | $0.09/GB | $0-900 depending on transfer |
| Cross-region replication | $0.02/GB | $200+ if enabled |
Best for: Teams deeply invested in the AWS ecosystem who need advanced features like S3 Object Lambda, S3 Tables, and tight IAM integration.
Watch out for: Egress fees can silently dominate your bill. A 10 TB dataset accessed frequently can easily generate $500-900/month in transfer costs alone.
Backblaze B2
Backblaze B2 is the budget-friendly option that popularized transparent cloud storage pricing. At $0.006/GB (approximately $6/TB), it undercuts AWS by nearly 4x on raw storage.
What Backblaze B2 costs in practice:
| Cost Component | Rate |
|---|---|
| Storage | $0.006/GB/month ($6/TB) |
| Download (egress) | Free up to 3x storage, then $0.01/GB |
| Upload | Free |
| API calls (Class B) | $0.004 per 10,000 |
| API calls (Class C) | $0.004 per 1,000 |
Best for: Backup and archive workloads where data is written once and rarely read. The 3x free egress allowance is generous for download-heavy use cases.
Watch out for: B2's S3-compatible API is not fully compatible. Some S3 SDK features don't work, and the performance ceiling is lower than AWS for high-throughput workloads. For AI training pipelines pulling large datasets repeatedly, the free egress cap can be hit quickly.
Wasabi
Wasabi positioned itself as the no-egress-fee alternative to AWS S3. At approximately $7.99/TB, it's competitive with B2 but with a simpler pricing model.
What Wasabi costs in practice:
| Cost Component | Rate |
|---|---|
| Storage | $7.99/TB/month |
| Egress | Free (up to storage amount) |
| API requests | Free (within fair use) |
| Minimum storage | 90 days (billed if deleted earlier) |
| Minimum object size | None |
Best for: Active storage workloads where data is read frequently. The free egress model makes it predictable for applications that serve data to users.
Watch out for: The 90-day minimum storage policy means Wasabi is not suitable for temporary or ephemeral data. If you store data for 30 days and delete it, you still pay for 90 days. For AI workloads with short-lived datasets, this can inflate costs significantly.
Cloudflare R2
Cloudflare R2 disrupted the market in 2024 with zero egress fees and a flat $0.015/GB storage rate. Built on Cloudflare's global network, it's designed for modern, distributed applications.
What Cloudflare R2 costs in practice:
| Cost Component | Rate |
|---|---|
| Storage | $0.015/GB/month ($15/TB) |
| Egress | Free |
| Class A operations (PUT, LIST) | $4.50 per million |
| Class B operations (GET, HEAD) | $0.36 per million |
Best for: Web applications and content delivery where egress would otherwise dominate costs. Cloudflare's CDN integration makes it ideal for serving assets globally.
Watch out for: R2's API is S3-compatible but not identical. Some advanced S3 features are missing. Storage pricing is roughly 2.5x B2's raw rate, so the zero-egress benefit only materializes if you would otherwise pay significant egress fees.
BHK Cloud
BHK Cloud takes a different approach: storage that is tightly integrated with GPU compute. At $2.49/TB, it offers the lowest raw storage price of any S3-compatible provider, with zero egress fees between GPU instances and storage.
What BHK Cloud costs in practice:
| Cost Component | Rate |
|---|---|
| Storage | $2.49/TB/month |
| Egress (GPU to storage) | Free |
| Egress (internet) | Competitive, no surprise fees |
| API requests | Included |
| GPU compute | $0.15/hr (RTX 3090, 24 GB VRAM) |
Best for: AI and ML teams that need GPU compute and storage together. Training pipelines, inference workloads, fine-tuning jobs, and rendering workflows benefit from the tight integration and zero internal egress.
Watch out for: BHK Cloud is purpose-built for AI workloads, not general-purpose web hosting. If you need a CDN, Lambda@Edge, or 50+ AWS service integrations, AWS S3 remains the more complete platform. But for the 80% of teams just running GPU workloads with S3-compatible storage, BHK Cloud is the most cost-effective option.

How to Choose a Cloud Storage Provider
Choose AWS S3 if:
- You need the broadest ecosystem of integrations and services
- Your team already uses AWS for compute, networking, and IAM
- You need advanced features like S3 Object Lambda, S3 Tables, or strong consistency guarantees
- Egress costs are manageable because your data stays within AWS
Choose Backblaze B2 if:
- Your primary use case is backup and archival
- You want the lowest raw storage cost among general-purpose providers
- You can work within the S3-compatible API limitations
- Your download volume stays within the free egress allowance
Choose Wasabi if:
- You want predictable pricing with no egress surprises
- Your data lives longer than 90 days
- You don't need deep integration with a specific cloud ecosystem
Choose Cloudflare R2 if:
- You serve assets globally and need CDN integration
- Egress fees would otherwise dominate your costs
- Your application already uses Cloudflare for DNS, Workers, or other services
Choose BHK Cloud if:
- You run AI/ML workloads and need GPU compute alongside storage
- You want the lowest storage cost at $2.49/TB
- You value zero egress between compute and storage
- You need fast GPU provisioning (under 60 seconds) with S3-compatible object storage
- You prefer transparent, usage-based billing without lock-in
Common Pricing Pitfalls to Avoid
Pitfall 1: Ignoring Egress Fees
AWS S3's $0.09/GB egress rate means downloading 10 TB costs $921.60. That's more than 3 years of BHK Cloud storage for the same data. Always model your expected download volume before choosing a provider.
Pitfall 2: Minimum Duration Penalties
Wasabi's 90-day minimum and AWS Glacier's 90-180 day minimums mean short-lived data can cost more than expected. For AI training datasets that change weekly, these penalties add up.
Pitfall 3: API Request Costs on Small Files
Storing millions of small files (like image datasets) generates API request charges that can rival storage costs. Providers like BHK Cloud that include API requests in the storage price are more predictable for these workloads.
Pitfall 4: Comparing Only the Headline Rate
The $0.023/GB vs $0.006/GB vs $2.49/TB comparison only makes sense when you factor in your specific access pattern, egress volume, and API usage. A cheaper headline rate can be more expensive in practice.
Final Verdict
Cloud storage pricing in 2026 is a story of specialization. AWS S3 remains the most feature-rich platform but charges accordingly. Backblaze B2 and Wasabi offer competitive general-purpose alternatives. Cloudflare R2 excels for web-facing applications with global audiences.
For AI and ML teams, BHK Cloud offers a compelling combination: the lowest storage price at $2.49/TB, zero egress between GPU compute and storage, RTX 3090 GPUs at $0.15/hr, and a clean S3-compatible API.
