Azure File 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.

File Storage

File Storage is now generally available. It uses industry standard SMB 3.0 protocol. Share files between applications running in your virtual machines using familiar Windows APIs or File REST API.

Storage Prices

These are the costs of storing your data in File Storage. The prices shown below are the monthly charges per GB of data stored. These prices vary based on the redundancy option that you choose.

LRS GRS
$- per GB $- per GB

Access Prices

These are the costs of SMB operations against your File data. These prices can vary based on the redundancy option that you choose.

LRS GRS
Put, Create Container Operations (per 10,000) $- $-
List Operations (per 10,000) $- $-
All other operations except Delete, which is free (per 10,000) $- $-

Import/Export

Data Redundancy Options

Locally Redundant Storage (LRS) Makes multiple synchronous copies of your data within a single datacenter.
Zone Redundant Storage (ZRS) Stores three copies of data across multiple datacenters within or across regions. For block blobs only.
Geographically Redundant Storage (GRS) Same as LRS, plus multiple asynchronous copies to a second datacenter hundreds of miles away.
Read-Access Geographically Redundant Storage (RA-GRS) Same as GRS, 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 page. 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 by default are set up to be geographically redundant. 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 RA-GRS is turned on 1st May and turned off on 5th May, the storage account will be charged for RA-GRS up to 30th May. After that, GRS pricing would start.

    If RA-GRS is turned on 1st May and turned off on 14th June, RA-GRS would be charged up to 14th June. On June 15, GRS 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 and can be seen here.

  • 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 -> Cool -> Hot tiers and cost of accessing data increases from Hot -> Cool -> 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 will be charged for a P0 (128-GB) disk. If any other type of Storage Account is used then you will only be billed for the storage space used to store the data that is written to the disk, regardless of the allocated disk size.

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