Azure Blob Storage
Pros
- + Four cost-optimized access tiers with fully published per-GB and per-operation prices
- + Mature redundancy ladder (LRS through RA-GZRS) with 11 nines claimed durability on LRS
- + Deep Azure integration: Entra ID auth, Private Link, lifecycle management, immutable storage
- + Reserved capacity discounts up to roughly a third on committed storage
- + Global footprint with EU, US, and APAC data residency plus sovereign clouds
Cons
- - No native S3 API — S3-designed tooling needs a third-party proxy
- - Egress, retrieval, and early-deletion fees often dwarf the capacity cost
- - Portal, RBAC, and account-kind surface area is a real learning curve
- - Cool/Cold/Archive tiers carry lower availability targets (99%) and minimum retention periods
- - SLA is 99.9% with capped service credits, not an availability guarantee
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
