Google Cloud Storage
Pros
- + Per-GiB-hour pricing published per class and location, prorated per second — no commitment required
- + Four storage classes put cold bytes as low as about $0.0012/GB-month (Archive)
- + Credit-backed SLA: 99.95% multi/dual-region Standard with 10–50% credits on miss
- + Real S3 interoperability (XML API, HMAC keys, V4 signing) plus a documented migration path
- + Always Free tier (5 GB-months, 50k Class B ops, 100 GB egress in US regions) can host a small real workload
Cons
- - Egress at $0.12/GiB (Premium) makes read-heavy serving expensive without a CDN in front
- - Cold classes carry minimum storage durations and retrieval fees — wrong class choices cost more than Standard
- - Many pricing dimensions (classes, placement, network tiers, operation classes) make forecasting hard
- - IAM and lifecycle configuration is a real learning curve and a common source of misconfiguration
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
