Object Storage Comparison 2026: Cloudflare R2 vs Backblaze B2 vs DigitalOcean Spaces vs Wasabi vs AWS S3

By CloudPicked Review Team  |  Last updated: September 2026

Choosing the right object storage provider can dramatically affect both your infrastructure costs and your application's performance. The market in 2026 has five major contenders: Cloudflare R2, Backblaze B2, DigitalOcean Spaces, Wasabi, and AWS S3. Each uses a different pricing model — some charge for egress bandwidth, some don't, and some have minimum storage durations that catch users off guard.

This guide compiles verified pricing data from each provider's official website as of September 2026 to help you make an informed decision.

What is Object Storage and Why Does It Matter?

Object storage is a cloud data storage architecture that manages data as discrete "objects." Unlike block storage (the disk attached to your virtual server) or traditional file systems, object storage is a flat namespace where each object consists of:

• The data itself (a file of any type and size)
• Metadata (key-value pairs describing the object)
• A unique identifier (URL/key)

Objects are accessed via HTTP APIs — primarily the S3-compatible API that AWS pioneered and every other provider now supports. Common use cases include:

• Website and app images, videos, and media files
• Database and server backups
• Static assets: CSS, JavaScript, fonts, PDFs
• Log files and long-term data archives
• Software distribution and user-uploaded content

Pricing Comparison: Object Storage 2026

Cloudflare R2 — Zero Egress for High-Traffic Workloads

Cloudflare R2 launched with one central promise: eliminate egress fees. Traditional cloud storage providers make significant revenue on bandwidth charges — at $0.09/GB, a website serving 10TB of images per month pays $900 in egress alone on AWS S3. R2 eliminates this cost entirely for data served through R2's S3-compatible API or a custom public domain.

R2 Standard storage is priced at $0.015/GB/month, with an Infrequent Access tier at $0.010/GB. The free tier includes 10GB storage, 1 million Class A operations, and 10 million Class B operations per month. R2 supports full S3-compatible API, making migration from S3 straightforward.

The main limitations: R2's storage tiers are limited compared to S3's six storage classes, the ecosystem of integrations is smaller, and advanced features like S3 Object Lambda or Intelligent-Tiering aren't available. For most web workloads, these limitations don't matter.

Backblaze B2 — Lowest Storage Price, Great for Backup

Backblaze B2 offers the lowest storage price in this comparison at approximately $0.007/GB/month ($6.95/TB/month), with 10GB permanently free. What makes B2 especially compelling is its Bandwidth Alliance partnership with Cloudflare, Fastly, and bunny.net — egress through these CDN providers is completely free, removing the single largest variable cost in object storage.

Unlike Wasabi, B2 has no minimum storage duration requirement and no minimum object size. This makes it suitable for applications that frequently update or delete files. Class A, B, and C API calls are free; only Class D transactions are charged ($0.004 per 10,000 calls, with 2,500 free daily).

• Storage: ~$0.007/GB/month
• Egress: Free up to 3× your stored data per month; unlimited free via Cloudflare/Fastly/bunny.net
• API: Class A/B/C free; Class D charged at $0.004/10,000 requests
• No minimum storage duration or object size
• 10GB free forever

DigitalOcean Spaces — Simple Flat Rate for DO Ecosystem

DigitalOcean Spaces takes a different approach with a straightforward $5/month flat plan that includes 250GiB of storage and 1TiB of outbound bandwidth. This predictability is valuable for small to medium projects where cost surprise is more painful than paying a slight premium.

The key integration advantage: data transfer between Droplets and Spaces buckets in the same region is free and counted against your Droplet's bandwidth allowance, not billed separately. If your application already runs on DigitalOcean, Spaces fits naturally into your existing billing and management workflow.

Spaces also offers cold storage at $0.007/GiB for archived data, and supports the S3-compatible API. Up to 100 buckets per account are supported.

Wasabi — No Hidden Fees, But Watch the Fine Print

Wasabi's pitch is simple: pay only for storage, nothing else. No egress fees, no API request fees. Storage is priced at approximately $7.99/TB/month (~$0.008/GB). This "one price for everything" model makes budgeting straightforward.

However, there are two critical constraints to understand before committing:

• 90-day minimum storage duration: If you delete an object before 90 days, you're still billed for the full 90-day period. Applications that frequently update or rotate files can end up paying significantly more than expected.
• 64KB minimum object size: Objects smaller than 64KB are billed as if they were 64KB. Storing thousands of tiny files becomes expensive quickly.

Wasabi also does not currently have data centers in Southeast Asia, which may result in higher latency for applications serving users in Thailand and the surrounding region. Check Wasabi's current datacenter locations at their official website before choosing.

AWS S3 — Industry Standard with the Richest Ecosystem

Amazon S3 is the service that defined the object storage category and set the S3 API standard that every other provider emulates. It remains the reference implementation for enterprise-grade cloud storage.

S3's main advantages are its ecosystem depth and storage flexibility. Six storage classes range from S3 Standard (frequent access) through S3 Intelligent-Tiering (automatic cost optimization), S3 Standard-IA and One Zone-IA (infrequent access), S3 Glacier Instant Retrieval, Glacier Flexible Retrieval, and Glacier Deep Archive (lowest cost for 7-10 year archival).

The trade-off is cost complexity. S3 Standard storage in the US East region is approximately $0.023/GB/month — higher than all other providers in this comparison. Egress to the internet costs approximately $0.09/GB after the first 100GB free per month. PUT and GET requests carry per-request charges. For large workloads, egress alone can dwarf storage costs.

• Storage: ~$0.023/GB/month S3 Standard (US East — verify current rates at aws.amazon.com)
• Egress: ~$0.09/GB after first 100GB/month
• PUT: ~$0.005 per 1,000 requests
• GET: ~$0.0004 per 1,000 requests
• Six storage classes including Glacier Deep Archive
• Free tier: 5GB for 12 months (new AWS customers)
• Widest set of integrations, certifications, and compliance frameworks

Strengths and Weaknesses at a Glance

Which Object Storage Provider Should You Choose?

• Thai-audience website with heavy media traffic: Cloudflare R2 — zero egress, Cloudflare PoPs in Thailand
• Daily server backups and long-term archives: Backblaze B2 — lowest storage price, free egress via Cloudflare
• Already using DigitalOcean Droplets: DigitalOcean Spaces — unified billing, free intra-region transfer
• Large files archived for 90+ days: Wasabi — no egress or API fees, but watch the minimum duration rule
• AWS-native infrastructure or enterprise compliance needs: AWS S3 — deepest ecosystem, but budget for egress costs
