Backblaze B2
What ChatGPT, Claude, Gemini & Grok actually say · September 2026 · incumbent
Visit backblaze.com ↗The verdict
Backblaze B2 appears in 4 AI-ranked categories — best position #2 for s3-compatible object storage for startups.
Lowest headline storage price ($6/TB/mo tier) with a genuinely simple, S3-compatible API and free egress up to 3× your stored data (plus fully free egress to Cloudflare via the Bandwidth Alliance); ideal for backup, media, and cost-sensitive startups that want predictable, cheap storage without a hyperscaler's complexity.
Gemini Industry-leading low baseline storage cost ($0.006/GB/month) combined with free egress through Bandwidth Alliance partners (e.g., Cloudflare, Fastly), simple S3 API compatibility, and high reliability for data-heavy startups.
Grok Lowest mainstream storage price (~$0.006/GB) plus free egress up to 3× stored volume (or unlimited via Cloudflare Bandwidth Alliance) and permanent 10 GB free tier deliver unmatched pure economics for backups, media, and private data; mature S3-compatible API and proven reliability for cost-sensitive teams
GPT Excellent cost-focused general storage at about $6.95/TB-month, with free routine transactions, no retention minimum, eleven-nines durability, Object Lock, and free egress up to three times average stored data
Where Backblaze B2 falls short, per the models
- GPT Its S3 API omits features such as object-level ACLs and tagging, while its infrastructure and native service ecosystem are narrower than AWS or Cloudflare
- Claude Single-company, fewer regions and less enterprise tooling/compliance breadth than AWS; not the pick if you need rich adjacent services (queues, analytics, deep IAM) sitting next to your buckets.
- Gemini Higher latency for global direct reads without a fronting CDN, and egress outside partner networks incurs per-gigabyte transfer fees.
- Grok Fewer regions and less native global edge performance than pure CDN-integrated alternatives when serving high-volume public traffic without a partner CDN

Free egress up to 3x your average monthly storage, and truly unlimited free egress through the Cloudflare/Fastly Bandwidth Alliance partnerships, plus among the lowest storage prices in the market; simple, S3-compatible, and battle-tested for backup and media serving. Excellent value when paired with a CDN.
Gemini Pairs rock-bottom base storage pricing with zero egress fees when routed through Bandwidth Alliance CDN partners (such as Cloudflare or Fastly), plus a generous free direct egress allowance of up to three times stored data volume.
Grok Lowest credible storage among mature S3-compatible services (~$6.95/TB) with free egress up to 3× stored volume and fully unmetered egress when fronted by Bandwidth Alliance partners (Cloudflare, Fastly, Bunny); for CDN-backed serving the all-in bill often undercuts R2 because storage is roughly half. Near-tie with R2 when a partner CDN is already in the path.
Where Backblaze B2 falls short, per the models
- Claude Egress beyond the 3x cap is billed, and raw performance/consistency and enterprise features (fine-grained IAM, global multi-region) lag the majors — best as a CDN origin, not a low-latency primary store.
- Gemini Direct public egress beyond the 3x allowance incurs per-GB costs, and centralized datacenter locations necessitate a third-party CDN to achieve global low latency.
- Grok Only two regions and a hard 3× cap unless you add a partner CDN; thinner feature set and fewer compliance checkboxes than the hyperscalers.

Top alternatives per the models: Cloudflare R2 · Wasabi · Hetzner Object Storage · Bunny.net
Excellent price-to-reliability ratio, straightforward S3 compatibility, low storage cost, generous included egress, and strong backup, archive, media, and CDN integrations
Gemini Exceptional cost efficiency with predictable per-terabyte storage pricing, reliable S3 compatibility, and free or heavily discounted egress partnerships via the Bandwidth Alliance.
Grok Very low storage costs, good S3 compatibility, generous free egress allowance, solid for backups/large archives; high real-world value for budget-conscious long-term storage.
Where Backblaze B2 falls short, per the models
- GPT Its smaller region footprint and thinner cloud-service ecosystem make it less suitable as the primary object layer for globally distributed applications
- Gemini Higher latency and lower burst throughput compared to tier-one hyperscalers, making it ill-suited for real-time, latency-critical read/write workloads.
- Grok Higher latency/variable performance for hot/frequent access workloads.

Top alternatives per the models: Amazon S3 · Cloudflare R2 · MinIO · Google Cloud Storage
Best raw price for warm AI datasets (~$6/TB/month), free egress up to 3x storage and unlimited to bandwidth-alliance partners (including Cloudflare), and the Overdrive tier introduced for AI/HPC customers pushes terabit-class throughput at a flat rate — a genuinely strong value play for training-data lakes on a budget.
GPT Excellent storage economics, straightforward S3 access, inexpensive egress with a generous free allowance, and an Overdrive tier for multi-petabyte AI/HPC workloads; strongest value for large warm datasets that do not require hyperscaler-native services.
Grok Exceptional value with low storage costs for bulk AI datasets (embeddings, weights, media), reliable S3 compatibility, pairs well with Cloudflare for effective egress-free access, strong for cost-conscious practitioners in storage-heavy but not ultra-low-latency workloads.
Where Backblaze B2 falls short, per the models
- GPT The standard service has a smaller location and integration footprint, while AI-grade Overdrive performance requires a multi-petabyte, sales-assisted commitment.
- Claude Fewer regions and a thinner enterprise feature set (IAM granularity, compliance tooling, replication options) than AWS/Cloudflare — teams with strict data-residency or complex access-control needs outgrow it.
- Grok Not the highest performance tier for GPU-starving training pipelines (better for archival/cold-ish access).
