IDrive e2
Pros
- + Flat $6/TB/month with no charges for API requests, ingress, or deletes
- + Free egress up to 3x stored volume per month — generous versus competitors
- + No minimum storage duration or deletion penalties
- + Object lock, versioning, cross-region replication, and webhook event notifications
- + Hundreds of integration guides and 15 regions across US, EU, Canada, and Asia
Cons
- - 1 TB billing minimum makes sub-terabyte buckets disproportionately pricey
- - The widely quoted $2.49/TB is a first-year promotion, not the ongoing rate
- - Published SLA exists but its uptime commitment is not publicly legible
- - Young service (launched 2022) from a company whose core business is backup software
- - S3 compatibility is a subset of the AWS API, not the full surface
Backblaze B2
Pros
- + $6.95/TB/month storage with no minimum file size or storage duration fees
- + Free egress up to 3x average monthly storage for all customers; unlimited free egress to partner CDNs/compute
- + Genuine S3-compatible API plus native API, with free Class A/B/C transactions
- + 11 nines claimed durability with published Vault math (20 shards across 20 pods)
- + EU data residency via the Amsterdam region; permanent 10 GB free tier
Cons
- - One region per account (fixed at creation); no cross-region buckets or read replicas
- - S3 compatibility is partial: no IAM roles, object tagging, or website hosting; bucket-level ACLs only
- - SLA is thin: 99.9% objective with 5–10% service credits
- - Storage price rose from $6 to $6.95/TB in May — value still strong, but the direction is upward
- - No compute, functions, or database services
