About
Backblaze B2 Cloud Storage is an S3-compatible object storage service for backup, active archiving, recovery, media workflows, and application data. The pricing page lists pay-as-you-go storage at $6 per TB per month, with free egress up to 3x average monthly storage and no minimum file size or storage duration fees.
The service includes a perpetual free allowance for the first 10 GB of storage, plus free API calls for B2 Reserve customers and limited free API calls for pay-as-you-go customers. It is aimed at developers and infrastructure teams that need object storage with predictable pricing, integration support, and optional annual capacity commitments.

Free Tier Value
This free tier is substantial: the first 10GB of storage is always free, with additional value from free egress, free API calls, and no minimum file-size or storage-duration fees. Compared with the cheapest paid plan starting at $6.95 per TB/month, the free allowance is roughly equivalent to about one paid month at the entry level, so a fair monthly value is about $6.95. A credit card is required to create the account, and the offer is capped rather than unlimited, which keeps the score below a fully paid plan.
