Backblaze B2 vs Wasabi: compare your workload, not just the headline price

Start with the data you actually retain

A useful comparison starts with average monthly stored data, including old versions, backup copies, and metadata. Peak capacity alone does not describe a monthly bill. Measure downloads separately, and record how frequently you delete or replace objects.

Backblaze B2 and Wasabi both offer object storage. The right choice depends on billing conditions and your workload as well as the published capacity price. Prices on this guide are deliberately supplied by the plan ledger rather than copied into the article; open the official sources and check the displayed verification date.

Minimum capacity changes small workloads

Wasabi pay-as-you-go has a minimum active storage charge of one binary terabyte. A decimal terabyte is 1,000 GB; a binary terabyte is approximately 1,099.51 decimal GB. StorageMetric converts the published rate and minimum to decimal units before applying them.

For a small backup, multiplying the data size by a headline per-GB rate can understate the minimum bill. B2 has a different billing model and a small free storage allowance. Enter 100 GB in the comparison desk to see why a minimum matters; then increase the workload to 2,000 GB and compare again.

Downloads and deletion are separate questions

B2 includes an internet-download allowance tied to average stored capacity, with an overage rate above that allowance. Wasabi's no-egress-charge policy has workload eligibility conditions. A scenario outside those conditions should not be labeled an unlimited free-download plan. StorageMetric leaves its total unavailable when downloads exceed the modeled policy.

Wasabi also applies a minimum storage duration to pay-as-you-go objects. Deleting or replacing data before that duration can create a bill for data you no longer actively store. Our steady-state estimate excludes that charge because it needs an object-age and deletion history. For frequently changing backups, request an invoice example from the provider before committing.

Compare a restore as well as an ordinary month

Try a low-download backup month, then model a full restore. Check API compatibility with your backup software, recovery throughput, account limits, and your preferred region. Test restore integrity instead of judging a backup solely by upload success.

The comparison desk estimates storage, modeled downloads, and read/write request categories. Other transaction categories, small-object billing, support, taxes, and optional services can add cost. The lowest displayed estimate is a useful starting point, not a service-quality ranking.
