Azure Blob Storage vs Storj

SEPT 2026 audit

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

Updated 12 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 Storj if…

Workloads that want data spread across many independent locations rather than one provider's region, at a storage rate close to the cheapest here.

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.
  • Storj: Egress is charged at the same $7 per TB as storage, so a read-heavy workload costs roughly double what the storage line suggests — the three free-egress providers here charge nothing for it.

3 sourced criteria separate them — see where, with sources, below.

Only criteria both providers publish appear here; a tinted cell marks a real difference. Criteria only one of them documents are listed below, and an absence there means we found no source — not that the feature is missing. How we source this.

The small bar above a value is inetGeek's own lean toward that side — computed from the same facts shown, never a number the provider published. See the picker below "The short answer" to weigh only the criteria you care about.

Documented by only one.

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.

Pricing modelAzure Blob Storage: Per region, per redundancy and per access tier, with storage, operations and bandwidth metered separately. Rates are published in Azure's public Retail Prices API rather than only on a pricing page, so a figure can be re-verified exactly rather than re-read.
Storage (entry plan)Azure Blob Storage: None. Azure Blob has no plans and no free storage band: the Hot LRS storage meter's cheapest tier begins at tierMinimumUnits 0 and charges $0.0208 per GB-month from the first gigabyte, with volume tiers only above 50 TB. Azure's free account offer sits outside the rate card and is time-limited, so it is not an allowance this criterion can record.
RegionsStorj: Distributed across tens of thousands of storage locations globally rather than named regions; a US-only option runs on SOC 2 type 2 compliant data centres.
Minimum storage durationAzure Blob Storage: None on Hot. Cool carries a 30-day minimum, Cold 90 days and Archive 180 days — the longest early-deletion window of any provider here, and three times S3's 90-day Glacier figure.
S3-compatible APIStorj: Supported
SOC 2Azure Blob Storage: Listed among Azure's compliance offerings (SOC 1, SOC 2, SOC 3) on Microsoft's own compliance documentation — a platform-wide list, not scoped to this specific service.

Questions this comparison answers.

Egress over allowance: Azure Blob Storage or Storj?

Azure Blob Storage: First 100 GB a month free, then $0.087 per GB over Microsoft's global network, falling to $0.083 above ~10 TB, $0.07 above ~50 TB and $0.05 above ~150 TB. Routing over the public internet instead is $0.08 at the first tier. This is Azure-wide bandwidth rather than a Blob-specific charge.

Storj: $7 per TB, the same rate as storage — reduced from $20 per TB on the Standard tier. Storj charges for egress where R2, Wasabi and Tigris do not, but at a tenth of what S3 charges.

Should I choose Azure Blob Storage or Storj?

Pick 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.

Pick Storj if Workloads that want data spread across many independent locations rather than one provider's region, at a storage rate close to the cheapest here.
