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 datacenter||Stores three copies of data across multiple datacenters within or across regions. For block blobs only.||Same as LRS, plus multiple asynchronous copies to a second datacenter hundreds of miles away||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.

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 and Cool access tiers. Append Blobs are also metered as Block Blobs
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 or Cool) and the redundancy option that you choose, as well as the amount of data you store.
|First 100 TB / Month||$0.01||$0.024||$0.02||$0.048||$0.025||$0.061|
|Next 900 TB / Month||$0.01||$0.0232||$0.02||$0.0463||$0.025||$0.0589|
|Next 4,000 TB / Month||$0.01||$0.0223||$0.02||$0.0446||$0.025||$0.0567|
|Over 5,000 TB / Month||Contact us|
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 or Cool) and the redundancy option that you choose.
|LRS||GRS and RA-GRS|
|Put Blob/Block, List, Create Container Operations (per 10,000)||$0.1||$0.05||$0.2||$0.1|

|Data Retrieval (per GB)||$0.01||Free||$0.01||Free|
|Data Write (per GB)||$0.0025||Free||$0.005||Free|
|Geo-Replication Data Transfer (per GB)||N/A||N/A||$0.02||$0.02|

Page Blob prices are the same as Standard Disk prices and can be found here.
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.
Block Blob storage is used for streaming and storing documents, videos, pictures, backups, and other unstructured text or binary data. Append Blobs are also metered as Block Blobs.
|First 1 TB / Month||$0.024 per GB||$0.03 per GB||$0.048 per GB||$0.061 per GB|
|Next 49 TB (1 to 50 TB) / Month||$0.0236 per GB||$0.0295 per GB||$0.0472 per GB||$0.0599 per GB|
|Next 450 TB (50 to 500 TB) / Month||$0.0232 per GB||$0.029 per GB||$0.0464 per GB||$0.0589 per GB|
|Next 500 TB (500 to 1,000 TB) / Month||$0.0228 per GB||$0.0285 per GB||$0.0456 per GB||$0.0579 per GB|
|Next 4,000 TB (1,000 to 5,000 TB) / Month||$0.0224 per GB||$0.028 per GB||$0.0448 per GB||$0.0569 per GB|
We charge $0.0036 per 100,000 transactions for Block Blobs. Transactions include both read and write operations to storage.

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 utilized 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 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 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 May 1 and turned off May 5, the storage account will be charged for RA-GRS through May 30. After that, GRS pricing would start.
If RA-GRS is turned on May 1 and turned off June 14, RA-GRS would be charged through June 14. On June 15, GRS pricing would take effect.
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, Queues.
No. Block Blob prices in general purpose Storage Account have NOT changed and can be seen here.
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 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.
When you create a Blob Storage Account, you can set the access tier as Cool or Hot. Cool tier has lower cost of storing data but 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. Below you can see an example.
Example: You have 50TB of data that you want to store in Blob Storage in US East 2 region. You send 10M HTTP operations to the account every month, 20% of which are Put Blob/Block, List and Create Container operations. You read 20TB of data from account every month, and write 10TB 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% * 10M /10,000 = 200||$0.1||$0.05||$20||$10|
|10,000 Operations, others||80% * 10M /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 Cool tier adds up to $770.4 vs $1242 in Hot tier. You will realize substantial cost savings by moving your data to the Cool tier in this example.
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 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.
If the empty 100GB disk is backed by a Premium Storage Account then you will be charged for a P0 (128GB) 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.
Yes. 99.9% read/write availability also applies to Premium Storage accounts.
