⚠️ The Fine-Print & Trap Inspector (How Cloud Storage Tricks You)
Storage rates alone do not determine your bill. Compare traffic, request charges, retention minimums and object-size billing rules:
1. The "Free Egress" Ratio & Fair-Use Caps
Many providers claim "No Egress Fees" in their hero marketing, but enforce strict ratios or overage penalties in their fine print:
- Wasabi (1:1 Ratio): Egress is only free if monthly download volume does not exceed total stored volume. Exceeding 1:1 can lead to account suspension or forced enterprise contracts.
- Backblaze B2 (3x Ratio): Free egress is capped at 3× stored data per month. Downloads above 3× are billed at $0.01/GB ($10/TB).
- MEGA S4 (5x Ratio + $17.49/mo Pro Base): Free egress is limited to 5× stored data on Pro Flexi ($17.49/mo base for 3 TB), then billed at $3.07/TB. Fixed Pro I is hard-capped at 3 TB transfer.
- iDrive e2 (3x Ratio): Egress free up to 3× stored volume, then $0.01/GB. Watch for steep promotional year-1 renewal jumps.
2. The 90-Day Minimum Retention Penalty
If you delete, overwrite, or rotate files before the minimum retention window expires, you are billed for the full duration ("Timed Deleted Storage"):
- Wasabi (90 Days): If you upload 10 TB of daily database backups and delete them after 7 days, you pay for 90 days of storage for each backup. A 7-day backup rotation effectively bills as ~12× your active storage!
- AWS Glacier Instant Retrieval (90 Days): Deleting archive files early triggers pro-rated 90-day early deletion fees.
- Rabata (30 Days) / iDrive e2 (30 Days): 30-day minimum retention rules on deleted chunks.
3. The $1,500/mo API Write Trap on Small Files
If you store millions of small files (IoT telemetry, user avatars, chat logs, game assets), API operation fees dwarf storage costs:
- AWS S3 Standard ($5.00/1M writes): Uploading 10M files/day = 300M Class A PUT requests/month = $1,500/mo in API fees alone, even if the data is only 500 GB ($11.50 storage)!
- Azure Blob Storage ($5.40/1M writes): Hot LRS write operations cost $0.054/10k = $1,620/mo in API fees on 300M writes.
- Cloudflare R2 ($4.50/1M writes): Class A mutations cost $4.50/1M = $1,345.50/mo on 300M writes (299M billable after the 1M/mo free Class-A tier) despite zero egress fees.
- AWS Glacier Instant ($100.00/1M writes): PUT operations cost $0.10/1k ($100/1M) = $30,000/mo on 300M writes. Workloads that write many small files to Glacier should model the request bill before committing.
4. The Minimum Monthly Invoice & Plan Floor
Small applications and micro-services often get billed 10x more than raw usage due to account minimums:
- Vultr Object Storage ($18.00/mo base): No micro-tiers; standard plan starts at $18/mo (includes 1 TB storage + 1 TB egress).
- MEGA S4 ($17.49/mo Pro Flexi base): Cannot be purchased as standalone $0.10 bucket; requires $17.49/mo Pro Flexi or $11.65/mo Pro I.
- Hetzner Object Storage ($7.57/mo base): Minimum $7.57/mo commitment (includes 1 TB storage + 1 TB egress).
- Wasabi ($7.99/TB, 90-day retention): Deleted objects still bill out their 90-day minimum duration, so churn-heavy buckets pay phantom storage.
- Storj ($5.00/mo invoice minimum): Invoices below $5 are rounded to $5.00 minimum once a card is attached.
5. The Cloud Lock-In Egress Ransom
Moving data into the big 3 clouds is free, but pulling it out to migrate or multi-cloud is penalized with punitive egress fees:
- AWS S3 & IBM Cloud ($90.00 / TB): Migrating a 100 TB dataset to another provider costs $9,000 in egress fees.
- Google Cloud Storage ($120.00 / TB): Migrating 100 TB costs $12,000 in egress ransom.
- Azure Blob Storage ($87.00 / TB): Migrating 100 TB costs $8,700.
6. The Cloudflare R2 "Action & Space" Mark-Up Trap
Cloudflare R2 heavily markets "$0.00 Egress", but claws back margins through expensive base storage and high Class A operation fees:
- Base storage costs differ: R2 is $15.00/TB, Bunny single-region is $10.00/TB, and Backblaze B2 is $6.95/TB. At 50 TB, their gross storage charges before allowances are $750.00, $500.00, and $347.50 per month respectively; egress, requests and replication are separate.
- Expensive Class A Action Fees ($4.50/1M writes): Uploading 10M files/day (300M PUTs/mo) costs $1,345.50/mo in write fees alone (after the 1M/mo free Class-A tier) on R2, compared to $0.00 on Hetzner, Bunny, or OVH.
- When R2 Actually Makes Sense: Only when outbound egress volume is massive (e.g. 50× stored data) and write volume is negligible. For general storage or backup, R2 is significantly more expensive.
🗄️ Beyond S3: The 4 Storage Paradigms (Which Do You Actually Need?)
Developers often default to S3 without realizing that Managed Storage Boxes, Decentralized Swarms, or Self-Hosted NVMe clusters can be cheaper or a better architectural fit for specific workloads — compare the catalogued rates below:
1. S3-Compatible Object Storage
HTTP API / Cloud-NativeFlat key-value storage accessed via HTTP REST APIs (AWS SDK, MinIO, S3cmd). Uses pre-signed URLs, multi-part uploads, and bucket versioning.
2. Managed Storage Boxes & NAS
Filesystem / SSH / BorgHierarchical Unix storage accessible via standard network protocols (BorgBackup, SFTP, rsync, WebDAV, CIFS/Samba). No API overhead.
3. Decentralized & Web3 Storage
Zero-Knowledge / Censorship-ProofClient-side encrypted chunks dispersed across tens of thousands of global node operators using Reed-Solomon erasure coding.
4. Self-Hosted On-Premises Engines
Bare Metal / Zero-EgressDeploying open-source S3-compatible daemon software on dedicated bare-metal servers or local NVMe clusters. High IOPS on local hardware and no outbound egress charges on-premises.

Curated Storage Guides & Decision Frameworks
What 10 TB of backup really costs → Three worked scenarios: retained backups, seven-day rotation, and a recovery month; including early-deletion charges and egress caps.
Deep-dive buying guides comparing cloud object storage for specific architectural requirements:
Backup workloads are write-heavy and read-rare. The key is low storage $/TB, zero retention penalties on file rotations, and free or low-cost recovery bandwidth.
Guide Best Zero-Egress S3 Storage Providers (2026) →Compare catalogued $0 egress rates and traffic allowances for asset delivery. Storage, requests, retention minimums and fair-use conditions can still affect the bill.
Guide European S3 Storage: Regions & Compliance Review →Compare European storage options, then review the selected region, data-processing agreement, subprocessors and applicable law with your compliance team. Provider location alone does not establish GDPR compliance or immunity from legal requests.
Guide Best Cloud Storage for AI Datasets & Model Weights (2026) →AI workloads require fast parallel read throughput for GPU clusters, massive capacity for training datasets, and zero egress fees for distributing model weights.
Guide Best S3 Storage for Video Streaming & Media Delivery (2026) →Streaming video and delivering large media files creates massive monthly data transfer. Hyperscaler egress rates of $90–$120/TB can exceed the entire storage bill for streaming workloads, so compare zero-egress and multiplier-allowance providers in the ranked table for your traffic ratio.
Guide Best S3 Storage for High-Volume Small Files (10M Files/Day) →When uploading 10 million files per day (300M PUTs/mo for telemetry, IoT, AI logs, or scraping), AWS charges $1,500/month just in API request fees. These zero-op-fee and low-request providers protect your unit economics.

Direct 1-on-1 feature breakdowns and cost differences across major cloud storage rivals:
Cloudflare R2 has a $0 egress rate in this catalog; AWS S3 Standard charges for outbound traffic after allowances. Both have request charges. Compare complete workload totals and required features rather than egress alone. Sources: S3 Standard pricing R2 pricing
Backblaze B2 ($6.95/TB) offers a 3x free-egress allowance and no minimum retention period. Wasabi ($7.99/TB) has a 90-day minimum retention period and a fair-use egress policy. These are base storage rates; compare allowances and workload totals before choosing. Sources: Wasabi Hot Storage pricing B2 Cloud Storage pricing
Backblaze B2 has an approximately 70% lower base storage rate ($6.95/TB vs AWS S3 Standard $23.00/TB) and free egress up to 3x stored volume. This percentage compares storage rates only, before allowances, requests and other workload charges. Sources: S3 Standard pricing B2 Cloud Storage pricing
Both offer zero egress fees. Cloudflare R2 ($15/TB) is better for web applications and CDN origins due to edge caching and zero retention minimums. Wasabi ($7.99/TB) is roughly half the storage price for bulk media archives. Sources: R2 pricing Wasabi Hot Storage pricing
Hetzner uses a base plan with included storage and traffic, then bills overages. OVHcloud Standard has a catalogued $0 egress rate. Compare the configured total rather than assuming either has the lowest entry price; region selection is not a compliance certification. Sources: Hetzner Object Storage pricing OVHcloud Object Storage (Standard) pricing
Both offer developer-friendly S3 storage for cloud compute workloads. DigitalOcean Spaces ($5/250GB) includes an integrated CDN edge with automatic SSL. Vultr ($6–$18/TB) provides high-speed NVMe clusters in over 32 global locations. Sources: DigitalOcean Spaces pricing Vultr Object Storage pricing
Hetzner has $0 Class A/B request rates in this catalog and a base plan with storage and traffic allowances. AWS S3 Standard bills requests separately. Compare storage, overages, requests and region requirements for your workload. Sources: Hetzner Object Storage pricing S3 Standard pricing
OVHcloud Standard has $0 egress and Class A/B request rates in the catalogued row. AWS S3 Standard bills outbound traffic and requests separately. Review the selected region and product terms before estimating the complete bill. Sources: OVHcloud Object Storage (Standard) pricing S3 Standard pricing
Hetzner Storage Box supports server backups via Borg, Restic, SFTP, and WebDAV. Backblaze B2 ($6.95/TB base storage) provides an S3 API for object storage applications and multi-cloud sync; these products use different access protocols. Sources: Hetzner Storage Box pricing B2 Cloud Storage pricing
Both catalogued rows have $0 egress rates. OVHcloud Standard has $0 Class A/B request rates, while Cloudflare R2 bills operations after its free allowances. A zero egress rate does not mean a zero total bill. Sources: OVHcloud Object Storage (Standard) pricing R2 pricing
Methodology
Prices captured 2026-09-01 from vendor pricing pages. Compute math: per-vendor storage cost × billable stored GB (after free tier) + egress cost × billable egress GB (after free tier / B2's 3x-stored policy) + Class A / B op costs × volume. EU-region prices used by default; switch Region to US where applicable.

Vendor scope: S3-compatible object-storage, managed Storage Boxes, and unified cloud storage; 27 vendors as of 2026-09-01. Rows where a rate is uncaptured sit unranked with an honest note rather than an estimate. Pricing pages are always the primary link; where an affiliate program is verified it is disclosed in that vendor's guide note: pricing tables and charts carry no referral labels (2026-08-26 owner steer), and links never change the price you pay.
Currency handling: the site standardizes on one display currency: US dollars. The ranked comparison and every vendor card show USD figures; EUR-billed vendors (Hetzner, MEGA S4, Scaleway, Exoscale) are converted at the fixed editorial FX rate (1 EUR = 1.166 USD, captured 2026-08-27) that also drives the ranking, and their invoices to you remain in euros. The price-register table below is the deliberate exception: it is a capture record of vendor list prices, so it shows each rate in its native billing currency, never converted.
Plan omissions: this comparison models one pay-as-you-go row per vendor. Cheaper plan shapes are not ranked: Backblaze B2 Overdrive (~$15/TB with unlimited free egress), iDrive e2 fixed-capacity annual plans (a 1 TB plan works out cheaper than their PAYG rate), and Hetzner's official dual EUR/USD pricing (this tool converts the captured EUR figure to USD for comparison). If your workload fits a fixed-capacity plan, check the vendor's page before deciding; our per-TB rates can overstate what you would actually pay.
Frequently Asked Questions
- What is the cheapest S3-compatible storage in 2026?
- The cheapest provider depends on your egress and operation pattern. Base storage rates include Bunny Storage ($10.00/TB, single-region), Backblaze B2 ($6.95/TB), and Hetzner Object Storage ($7.30/TB). These are storage rates, not complete bills; use the calculator to include allowances, minimums, requests and egress.
- Do any catalogued rows avoid the classic storage traps?
- The catalogued Hetzner and OVHcloud rows have 0-day minimum retention and $0 Class A/B request rates. Storage, base-plan and traffic charges may still apply. Check current pricing and product terms; region choice is not a compliance certification. Sources: Hetzner Object Storage pricing OVHcloud Object Storage (Standard) pricing
- Is Cloudflare R2 really free egress, and why can it be a trap?
- Cloudflare R2 has a base storage rate of $15.00/TB, compared with $10.00/TB for Bunny single-region and $6.95/TB for B2. Free internet egress does not eliminate storage and request charges; compare the full workload in the calculator.
- What is the 90-day minimum retention penalty?
- Providers like Wasabi and AWS Glacier Instant Retrieval enforce a 90-day storage minimum. If you create a 1 TB backup and delete or replace it after 3 days, you are still billed for the remaining 87 days as "Timed Deleted Storage". For daily backup rotation, this multiplies your bill by up to 30x.
- What is the difference between S3 Object Storage and a Storage Box?
- S3 Object Storage is accessed over HTTP REST APIs using buckets and keys. Storage Boxes (like Hetzner or rsync.net) are Unix-level network drives accessed via SSH, BorgBackup, rsync, SFTP, and Samba. Storage Boxes are significantly cheaper for server backups and disaster recovery.
- How does Backblaze B2's 3× free egress policy work?
- Backblaze B2 provides free monthly egress up to 3× your average stored data volume. Storing 10 TB gives you 30 TB of free download transfer every month. Overage beyond that is billed at just $0.01/GB ($10/TB), or $0.00 via the Cloudflare Bandwidth Alliance.
