Azure Blob Storage vs Wasabi

SEPT 2026 audit

A comparison of Azure Blob Storage and Wasabi built from values read directly from each provider's own documentation, with the source recorded against every figure.

Reviewed by Palash BagchiUpdated 20 criteria comparedSources last checked

The short answer

Choose Azure Blob Storage if…

Workloads already on Azure, where keeping storage in the same region as the compute avoids the bandwidth charge that dominates an object storage bill.

Editorial · Palash Bagchi · approved

Choose 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.

Editorial · Palash Bagchi · approved

Consider something else if…

  • Azure Blob Storage: Egress is charged beyond the first 100 GB a month, where R2, Wasabi and Tigris charge nothing — and Azure's rates vary by region and redundancy, so a quoted figure only holds for the combination it was read 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.

These criteria are published by one provider and not the other. An absence here means we have not found a source, not that the feature is missing — except where we say we read the other provider's own page on a given date and it does not state it. Those rows lean, and the provider can correct them with a link.

What the free plan includesAzure Blob Storage: $200 of Azure credit for 30 days on a new account. Azure separately lists services that are always free and services free for 12 months to new customers, which is an account-wide programme rather than a Blob Storage allowance.
