Consider something else if…
- Backblaze B2: Egress is only free to that 3x ceiling. A bucket read far more often than its size, like a public media library, is the shape this pricing is not built for.
- Wasabi: The flat rate is $7.99 per terabyte whether you store a gigabyte or a terabyte of it, so small buckets pay for capacity they are not using. Check Wasabi's own terms for minimum storage duration before storing anything short-lived.
