Storj
Pros
- + $7/TB storage and $7/TB egress on Standard — far below hyperscaler egress economics
- + 11 nines durability target via erasure coding across independent nodes; no single point of failure
- + S3-compatible gateway plus Object Mount (two licenses free with every account)
- + Advanced tier pins data to U.S. SOC 2 Type 2 compliant data centers for residency needs
- + Open source, client-side encryption by default, and a 30-day trial with no credit card
Cons
- - No permanent free tier — 30-day trial only, then a $5 monthly minimum fee that is not a credit
- - Pricing changed twice in a year; the 2026 migration's opt-out deletes your data within 45 days
- - 50KB object minimum and 30-day minimum retention punish small-object and churn-heavy workloads
- - Performance varies with node geography versus single-region centralized storage
- - New ownership (Inveniam, October 2025) and STORJ token economics add strategy risk
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
