Azure Storage Pricing
Reliable, economical cloud storage for both big and small data.
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. Here’s how they compare:
|Locally Redundant Storage (LRS)||Zone Redundant Storage (ZRS)||Geographically Redundant Storage (GRS)||Read-Access Geographically Redundant Storage (RA-GRS)|
|Makes multiple synchronous copies of your data within a single data centre||Stores three copies of data across multiple data centres within or across regions. For Block Blobs only.||Same as LRS, plus multiple asynchronous copies to a second data centre hundreds of miles away||Same as GRS, plus read access to the secondary data centre|
For more details on redundancy options and how they can be used for high availability, please refer to the Azure Storage replication page. Please note that not all redundancy types are available for all storage types.

Important: The price in R$ is merely a reference; this is an international transaction and the final price is subject to exchange rates and the inclusion of IOF taxes and an eNF will not be issued.
Azure Germany is available to customers and partners in the European Union (EU) and European Free Trade Association (EFTA) and provides data residency in Germany with additional levels of control and data protection with a modest price uplift over global cloud offerings (% varies per service).
Queues provide a reliable messaging solution for your apps.

- If I use Storage for only a few days a month, is the cost prorated?
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 utilised 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.
- How do I know which data redundancy option (LRS, GRS, RA-GRS) I’m using?
Storage accounts by default are set up to be geographically redundant. You can change these setting 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 for using the service management API.
- How does RA-GRS billing work?
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 on 1 May and turned off on 5 May, the storage account will be charged for RA-GRS until 30 May. After that, GRS pricing would start.
If RA-GRS is turned on on 1 May and turned off on 14 June, RA-GRS would be charged until 14 June. On 15 June, GRS pricing would take effect.
- What is a Blob Storage Account and how is it different to a general-purpose Storage Account?
Blob Storage Account is a storage account specialised 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.
- Have the prices of Block Blobs in general-purpose storage accounts changed?
No. Block Blob prices in general-purpose Storage Account have NOT changed and can be seen here.
- When looking at my Azure bill, how can I tell whether I am being charged for Blob Storage Account or Blobs in general-purpose storage accounts?
If you see “Hot” or “Cool” 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 that you are using and being charged for Blob Storage Accounts, while “Standard IO – Block Blob (GB)” is the meter associated with use of Block Blobs in general-purpose storage accounts.
- What are the Hot and Cool access tiers and how should I determine which one to use?
When you create a Blob Storage Account, you can set the access tier as Cool or Hot. The Cool tier has a lower cost of storing data but a higher cost of accessing data, and it should be used for data that is not frequently accessed and has lower availability SLA requirements. If you do not 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 storage based on your actual usage. An example is shown below.
Example: You have 50 TB of data that you want to store in Blob Storage in US East 2 region. You send 10 million HTTP operations to the account every month, 20% of which are Put Blob/Block, List and Create Container operations. You read 20 TB of data from the account every month, and write 10 TB of data. This is how your total cost will be calculated in Hot vs Cool.
Unit of measure Usage volume Price in Cool Price in Hot Monthly cost in Cool Monthly cost in Hot GB per month 50*1,024= 51,200 $0.01 $0.024 $512 $1228.8 10,000 Put Blob/Block, List, Create Container operations 20% * 10 million/10,000 = 200 $0.1 $0.05 $20 $10 10,000 operations, others 80% * 10 million/10,000 = 800 $0.01 $0.004 $8 $3.2 GB of data retrieved 20 * 1,024 = 20,480 $0.01 $0 $204.8 $0 GB of data written 10 * 1,024 = 10,240 $0.0025 $0 $25.6 $0 Total monthly cost $770.4 $1242
In this example, the total monthly cost of the Cool tier is $770.4, compared to $1242 in the Hot tier. You will realise substantial cost savings by moving your data to the Cool tier in this example.
- Am I charged for Data Retrieval if I toggle my Blob Storage Account from Cool to Hot?
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 x $0.01 = $1 for Data Retrieval.
- Am I charged for Data Writes if I toggle my Blob Storage Account from Hot to Cool?
No – If you toggle your account from Hot to Cool, you will not be charged for Data Writes. You are only charged for Data Writes if you directly write data to your Blob Storage Account with Cool access tiers.
- What is the Geo-Replication Data Transfer charge?
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.
- If I attach an empty 100 GB disk to my virtual machine, will I be charged for the entire 100 GB or just for the storage space I use?
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’ll only be billed for the storage space used to store the data that is written to the disk regardless of the allocated disk size.
- Is Premium Storage covered under the same SLA as other storage services?
Yes. 99.9% read/write availability also applies to Premium Storage Accounts.
