Pricing Analysis
Backblaze's B2 Cloud Storage at $6/month for pay-as-you-go object storage undercuts AWS S3 ($0.023/GB minimum) by offering predictable monthly minimums rather than variable per-GB pricing. The $6 minimum covers ~260GB at S3 pricing, making B2 economical for small-to-mid workloads with consistent storage footprints. For larger deployments, B2's $0.006/GB pricing outperforms S3's $0.023/GB standard tier, a 4x cost advantage that explains B2's appeal to backup vendors and archival workflows.
B2 Overdrive ($15/month) is a strategic tier targeting enterprise backup vendors who require terabit-speed ingestion and dedicated private vaults. The unlimited free egress is the key differentiator from AWS and Azure, which charge $0.02-0.05/GB for egress. For vendors moving petabytes of backup data off platform, Overdrive's egress pricing elimination is economically material, justifying the $15 monthly premium over standard B2.
Backblaze's '3x monthly free egress' policy on standard B2 is designed to enable archival use cases without penalizing occasional retrieval. However, this policy creates a pricing cliff for high-egress workflows: the fourth egress operation in a month incurs $0.01/GB, making retrieval-heavy patterns more expensive than S3's flat $0.02/GB rate. The tier structure assumes backup workflows prioritize write density over retrieval frequency.
Strengths
- B2 pay-as-you-go pricing at $6/month minimum is 4x cheaper than AWS S3 for small-to-mid storage workloads.
- 3x free monthly egress on B2 standard supports archival retrieval patterns without incurring egress fees for typical recovery operations.
- B2 Overdrive's unlimited free egress eliminates the primary cost variable for backup-at-scale vendors, creating predictable unit economics.
Considerations
- 3x free egress policy creates pricing cliff for high-retrieval workflows, where fourth operation incurs variable $0.01/GB charges.
- API calls are free, but ecosystem integration requires vendor support for B2 protocol (S3-compatible but not identical), limiting portability.
- Small monthly minimum ($6) is attractive, but egress charges accumulate for unexpected recovery scenarios beyond the 3x monthly allowance.
Backup vendors and archival services that optimize for write density and predictable egress patterns.
Backblaze's $6/month entry price and 4x S3 cost advantage are designed to capture backup vendors; Overdrive's unlimited egress targets enterprise scale.
