Azure Storage Pricing

Reliable, economical cloud storage for data big and small

Azure has five types of storage—Blobs, Files, Disks, Tables, and Queues. See how they work

Your total cost depends on how much you store, the volume and type of storage transactions and outbound data transfers, and which data redundancy option you choose. See how they compare in the "Data Redundancy Options" section.

Blob Storage accounts

Block Blob storage is used for streaming and storing documents, videos, pictures, backups, and other unstructured text or binary data. Below is the pricing for dedicated Blob storage accounts with Hot, Cool and Archive (where available) access tiers. Append blobs are also metered as block blobs.

Storage prices

These are the costs of storing your data in block blobs. The prices shown below are the monthly charges per GB of data stored. These prices vary based on the access tier of Block Blob storage (Hot, Cool or Archive) and the redundancy option that you choose, as well as the amount of data you store. The Archive prices shown below are preview prices and will go up at general availability. Please note that Archive preview is only available in East US 2 region. Make sure you select that region to see the pricing.

Access prices

These are the costs of HTTP operations against your block blob data, as well as the cost of retrieving data from or writing data into your block blobs. These prices vary based on the access tier of Block Blob storage (Hot, Cool or Archive) and the redundancy option that you choose. The Archive prices shown below are preview prices and will go up at general availability. Please note that Archive preview is only available in East US 2 region. Make sure you select that region to see the pricing.

Please note that Put Blob/Block, Set Tier, and Delete are the only valid archive operations. Setting the tier from Archive to Hot or Cool will take up to 15 hours to complete for block blobs smaller than 50 GB.

See the prices for Block Blob storage in general-purpose storage accounts.

Page Blob prices are the same as Standard Disk prices. See the pricing page.

Blob storage accounts with Hot and Cool access tiers are not available in this region yet but will be coming soon. Please see below for pricing of block blobs in general-purpose storage accounts in this region.

Access prices

We charge $- per 10,000 transactions for block blobs. Any type of operation against the storage account is counted as a transaction, including reads, writes, and deletes.

Data redundancy options

locally redundant storage Makes multiple synchronous copies of your data within a single datacenter.
zone redundant storage Stores three copies of data across multiple datacenters within or across regions. For block blobs only.
geographically redundant storage Same as locally redundant storage, plus multiple asynchronous copies to a second datacenter hundreds of miles away.
read-access geographically redundant storage Same as geographically redundant storage, plus read access to the secondary datacenter.

For more details on redundancy options and how they can be used for high availability, please refer to Azure Storage replication. Please note that not all redundancy types are available for all storage types.

FAQ

General

  • Yes. Storage capacity is billed in units of the average daily amount of data stored, in gigabytes (GB), over a monthly period. For example, if you consistently used 10 GB of storage for the first half of the month, and none for the second half of the month, you would be billed for your average usage of 5 GB of storage.

  • Storage accounts are set up to be geographically redundant by default. You can change these settings to read-access geographically redundant, or locally redundant through the Microsoft Azure classic portal, or the service management API. You can also check the status on the portal on using the service management API.

  • Storage accounts will be charged for a minimum of 30 days from the time the service is enabled. For example, if read-access geographically redundant storage is turned on May 1 and turned off May 5, the storage account will be charged for read-access geographically redundant storage through May 30. After that, geographically redundant storage pricing would start.

    If read-access geographically redundant storage is turned on May 1 and turned off June 14, read-access geographically redundant storage would be charged through June 14. On June 15, geographically redundant storage pricing would take effect.

Blob storage

  • A blob storage account is a storage account specialized for storing data as blobs and allows users to specify an access tier based on the frequency of access for the data in that account. General-purpose storage accounts can be used to store blobs as well as files, disks, tables, and queues.

  • No. Block blob prices in general-purpose storage accounts have not changed. See the prices.

  • If you see “Hot,” “Cool,” or “Archive” in the resource name, it means that the charge is associated with blob storage accounts. For example, when you see “Standard IO - Cool Block Blob (GB)” in your bill, it means you are using and being charged for blob storage accounts, while “Standard IO – Block Blob (GB)” is the meter associated with the use of block blobs in general-purpose storage accounts.

  • In blob storage accounts, you can set the access tier of a blob as Hot, Cool, or Archive. Storage GB pricing increases from Archive to Cool to Hot tiers, and cost of accessing data increases from Hot to Cool to Archive tiers. The Archive and Cool tiers should be used for rarely and infrequently accessed data respectively, with lower availability SLA requirements. If you don't know the access pattern for your data, we recommend that you start with the Hot tier for at least a month, and then determine whether you can save costs by moving to Cool and Archive storage based on your actual usage.

  • You will be charged for data retrieval when you toggle your blob storage account from Cool to Hot—for example, if you have 100 GB of data in a blob storage account and you toggle that account from Cool to Hot, you will be charged 100 * $0.01 = $1 for data retrieval.

  • No. If you toggle your account from Hot to Cool, you will not be charged for data writes. You will only get charged for data writes if you directly write data to your blob storage account with Cool access tiers.

  • When you write data into GRS accounts, that data will be replicated to another Azure region. The Geo-Replication Data Transfer charge is the bandwidth cost of replicating that data to another Azure region.

Disk storage

  • If the empty 100-GB disk is backed by a Premium Storage account, then you'll be charged for a P0 (128-GB) disk. If any other type of storage account is used, then you’ll only be billed for the storage space used to store the data that's written to the disk, regardless of the allocated disk size.

  • Yes. 99.9% read/write availability also applies to Premium Storage accounts.
