Introduction: Choosing Low-Cost Cloud Storage
For individual developers, startups, or projects requiring large-scale data storage, cost is a key factor when selecting a cloud storage service. The overseas market offers several services that emphasize 'low cost' as a core selling point, challenging traditional cloud giants with optimized pricing models (e.g., free egress, flat rates). This article focuses on two prominent overseas services known for their cost-effectiveness and developer ecosystems: Backblaze B2 and Wasabi, analyzing their latest features and suitable use cases.
Backblaze B2 Cloud Storage
Provider: Backblaze
Product: Backblaze B2 Cloud Storage
Overview: Backblaze has focused on computer data backup since 2007, later expanding successfully into the enterprise cloud storage market. With its simple pricing and excellent reliability, it has become a popular choice for developers and SMBs. Its storage scale continues to grow, positioning it as a leader in the value-for-money market.
Key Features & Advantages:
- Deep Integration with Cloudflare (Bandwidth Alliance): This is one of B2's most attractive features. Traffic from a B2 bucket to Cloudflare's CDN edge nodes is completely free. This allows you to store data on low-cost B2 and distribute it globally via Cloudflare's network at no cost, significantly reducing content delivery expenses.
- Transparent, Simple Pricing: Low storage costs and highly competitive download (egress) fees. No hidden costs in calculations.
- Comprehensive Developer Tools: Full-featured CLI, S3-compatible API, and rich SDKs for easy integration and automation.
- High Durability & Availability: Data is stored across multiple data centers using erasure coding for security.

Pricing Reference (2024): Storage costs approximately $6/TB/month. Download fees are typically lower than major public clouds. Combined with free Cloudflare traffic, it's ideal for static websites, app backups, and media asset storage.
Wasabi Hot Cloud Storage
Provider: Wasabi Technologies
Product: Wasabi Hot Cloud Storage
Overview: Wasabi disrupts the market with 'simple, predictable pricing,' focusing on high-performance 'hot' cloud storage at prices far below AWS S3 Standard. It targets primary enterprise storage needs directly, offering fast data access.
Key Features & Advantages:
- Flat Rate, No Egress Fees: This is Wasabi's biggest selling point. Its pricing model is extremely simple: charge based on storage capacity (e.g., ~$6.99/TB/month) with no data download (egress) fees. This makes cost forecasting very easy, especially for scenarios with frequent data access/downloads.
- High-Performance Access: Positioned as 'hot' storage, meaning fast data retrieval, suitable for applications requiring frequent read/write operations.
- Full S3 Compatibility: Uses the standard S3 API, allowing easy migration of existing S3-based applications without code changes.
- Global Data Center Footprint: Regions in the US (East, West), Europe (Amsterdam), and APAC (Tokyo, Japan) to meet data residency and low-latency needs.

Important Note: Wasabi has a minimum storage duration and minimum capacity billing policy (e.g., 90-day minimum). Deleting data before the minimum period may incur charges. Review their billing terms carefully to ensure they match your usage pattern.
Comparison & Selection Guide
| Feature | Backblaze B2 | Wasabi |
|---|---|---|
| Core Pricing Model | Storage fee + Download fee (free to Cloudflare) | Flat storage fee, no download fees |
| Best Use Cases | Static sites with CDN, archival backup, infrequently accessed data | Frequently accessed hot data, video surveillance, data lakes, direct download services |
| API Compatibility | S3 Compatible | S3 Compatible |
| Free Tier | Offers limited free storage (typically 10GB) | No permanent free tier, offers free trial |
| Cost Predictability | Medium (variable egress, controllable via Cloudflare) | High (no egress fees, cost tied only to storage) |
Selection Advice:
- Choose Backblaze B2 if: Your data is primarily distributed via a website/CDN, leveraging the free Cloudflare alliance; or you need very low-cost long-term archival storage.
- Choose Wasabi if: Your application requires frequent, high-speed data access with high download volume; you want completely predictable monthly billing for simplified cost management.
Conclusion
Backblaze B2 and Wasabi represent the trend toward low-cost, high-transparency cloud storage. B2, through its ecosystem partnership with Cloudflare, achieves near-free bandwidth costs in specific scenarios. Wasabi eliminates egress fee uncertainty with its 'all-in' pricing model. When choosing, evaluate based on your data access patterns, geographic requirements, and cost structure. Utilize both services' trial periods for performance and cost testing before committing to production.
