## Which should you choose?

Pick Backblaze B2 if Bulk capacity where egress is predictable — free up to three times what you store each month, which covers most backup and archive patterns comfortably at $6.95 per terabyte.

Pick Wasabi if Anyone who wants one number. Capacity is the only charge — no egress fees, no API request fees — which makes the bill predictable in a way nothing else in this category manages.

Consider something else: 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.

Consider something else: 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.
