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
Amazon S3
Pros
- + Designed for 11 nines durability with cross-AZ replication by default and strong read-after-write consistency
- + The S3 API is the industry standard — code written in 2006 still works, and third-party compatibility is everywhere
- + 23x cost ladder from Standard down to Glacier Deep Archive at $0.00099/GB-month, with lifecycle automation
- + Deepest storage feature set available: versioning, Object Lock, replication, inventory, event notifications, access management
Cons
- - Egress at $0.09/GB and per-request pricing produce surprise bills for chatty or restore-heavy workloads
- - IA and Glacier classes add retrieval fees and latency — the restore path must be priced separately
- - Policy configuration (bucket policies, IAM, Block Public Access, KMS keys) is complex and historically error-prone
- - SLA (99.9%/99.0%) is far below the durability figure — availability and durability are different promises
