Azure Storage Pricing: Blobs, Files, Tables and Managed Disks

Azure provides five main storage products: Azure Blob Storage, Azure Files, Azure Table Storage, and Disk Storage. Each has a different pricing structure with costs per GB stored, data transfer costs, and charges for data operations.

In this post, we’ll briefly review these storage service, explain each pricing model, and provide pricing examples for common scenarios, as part of our series of articles about Azure cost management. We’ll also show how NetApp Cloud Volumes ONTAP can help you reduce storage costs on Azure.

In this article, you will learn:

• Introduction to Azure Storage services
• Azure Blob Storage pricing
• Azure Files pricing
• Azure table storage pricing
• Azure managed disks pricing
• Azure NetApp Files Pricing
• Reducing Azure storage costs with Cloud Volumes ONTAP

Introduction to Azure Storage Services

The following table summarizes Azure’s storage options. In the following sections we’ll provide pricing details for each service.

Also refer to our in-depth articles about Azure SQL pricing ,which explains service options and pricing models for Azure’s Microsoft SQL Platform as a Service (PaaS) offering, and our article about Azure backup pricing, which explains the cost of backup storage on Azure Blob Storage, with an emphasis on using storage tiering to conserve costs.

Azure Blob Storage Pricing

Azure block blob storage is priced according to several factors:

• How much data you store
• Duration of data storage (prices defined per GB-month)
• Operations performed on the data
• Data redundancy options
• Storage tier—premium (high throughput), hot (99.9% availability), cool (accessed at least once per month), archive (stored for at least 180 days, can tolerate retrieval latency)
• On-demand vs. reserved storage (you can reserve blob storage for 1-3 years and receive discounts)

Azure pricing is subject to frequent changes, and below we show only the most common pricing options. For full, updated pricing please consult the official pricing page.

Below you can see on-demand storage prices for the West US 2 region, for three common redundancy options:

• Locally redundant storage (LRS)—11 9’s of durability within one Azure datacenter
• Zone-Redundant Storage (ZRS)—12 9’s of durability, replicated across three AZs
• Geo-Redundant Storage (GRS)—16 9’s of durability, replicated across three AZs in primary and secondary region, with failover

In addition, Azure Blob Storage charges for data transfer: 

• Data retrieval is free for the hot tier, and costs $0.01 for cool data tier and $0.02 for archive data tier, across most redundancy options.
• Data writes are free for all tiers and redundancy options.

Azure Files Pricing

Azure Files Pricing depends on the following factors:

• Quantity of data stored
• Duration of data storage (prices defined per GB-month)
• Operations performed on the data
• Data redundancy options
• Storage tier—premium (high throughput, served on SSD drive) or standard

The following table shows Azure Files data storage prices for the West US 2 region.

In the Premium Tier, you don’t pay for storage actually used, but for storage provisioned. You define the amount of storage to provision, and Azure Files provides IOPS and throughput appropriate for the share size. To learn more about the provisioned IOPS model see the official pricing page.

Snapshot storage is priced separately. For LRS redundancy, snapshot storage costs $0.20 per provisioned GB for the premium tier and $0.06 for the normal tier.

Data operations are charged as follows, for LRS redundancy:

• $0.015 for 10,000 put, create container, or list operations
• $0.0015 for all other operations except delete
• No charge for delete operations or geo-replication data transfer

Azure Table Storage Pricing

Azure Table Storage is priced based on GB-month used, depending on your selected redundancy level. Pricing is shown for West US 2 region (see the official pricing page for up-to-date prices).

Data operations and data transfer is charged at $0.00036 per 10,000 transactions.

Azure Managed Disk Pricing

Azure Managed Disks are priced according to the following criteria:

• Disk category—Premium SSD, Standard SSD, Standard HDD, Ultra Disk (next generation SSD with configurable performance and low latency)
• Disk size—disks are charged for their entire capacity, not actual usage
• Data transactions—a charge per 10,000 transactions on a disk
• Data redundancy options

Most disks offer limited IOPS and throughput, depending on the disk category

A few examples of monthly costs for managed disks, for LRS redundancy, in West US 2 region.

See the official pricing page for updated pricing, and to understand how IOPS and throughput provisioning works for the Ultra Disk category.

Azure NetApp Files Pricing

Azure NetApp Files is priced according to the three performance tiers:

• Standard Tier - suitable for static web content, file shares, database backups
• Premium Tier - suitable for databases, enterprise apps, analytics, messaging queues
• Ultra Tier - performance-intensive applications including high performance computing (HPC)

Pricing is based on the amount of storage used, priced per GB per hour across the three tiers.
