Ranked **#4 of 12** on default weights.

| True cost /mo (USD) | $26.95/mo | Inferred | 2026-07-23 | https://www.backblaze.com/cloud-storage/pricing | Storage 1 TB x $6.95 = $6.95. Free egress allowance is 3x stored = 3 TB, so 2,000 GB billable x $0.01 = $20.00. Requests $0.00: B2 now makes Class A, B and C calls free on pay-as-you-go, which covers all 10 M of this scenario's uploads, downloads and listings. Total $26.95. Serving through Cloudflare instead would zero the $20 under the Bandwidth Alliance, leaving $6.95. | https://toolweight.com/compare/s3-compatible-storage#backblaze-b2--true_cost_usd |

**Verdict.** The sensible cheap, feature-complete middle, but no APAC region rules it out for Australia.

## Alternatives

- [AWS S3](https://toolweight.com/tools/aws-s3), The API everything else copies, and by far the most expensive egress in this roster.
- [Bunny Storage](https://toolweight.com/tools/bunny-storage), Edge storage built as a CDN origin, with its own API rather than a faithful S3 one.
- [Cloudflare R2](https://toolweight.com/tools/cloudflare-r2), S3-compatible object storage with zero egress fees, on Cloudflare's network.
- [DigitalOcean Spaces](https://toolweight.com/tools/digitalocean-spaces), Bundled object storage plus free CDN, priced as a flat base fee with overages.
- [Hetzner Object Storage](https://toolweight.com/tools/hetzner-object-storage), The cheapest credible S3 endpoint in Europe, with a deliberately thin feature set.
- [iDrive e2](https://toolweight.com/tools/idrive-e2), USD 4/TB S3-compatible storage with zero-egress marketing and a fair-use cap.
- [MinIO](https://toolweight.com/tools/minio), The self-hosted S3 reference implementation, your hardware, your bandwidth, your SLA.
- [Scaleway Object Storage](https://toolweight.com/tools/scaleway-object-storage), European-sovereign S3 storage with multi-AZ classes and a real IAM system.
- [Storj](https://toolweight.com/tools/storj), Decentralised erasure-coded storage: USD 4/TB stored, USD 7/TB egress, no regions.
- [Tigris](https://toolweight.com/tools/tigris), Globally distributed S3-compatible storage that caches objects near readers.
- [Wasabi](https://toolweight.com/tools/wasabi), Flat-rate hot storage with no egress or API fees, bounded by a fair-use cap.
