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.
US government entities are eligible to purchase Azure Government services from a licensing solution provider with no upfront financial commitment or directly through a Pay-As-You-Go online subscription.

Azure Germany is available to customers and partners doing business in the European Union (EU) and European Free Trade Association (EFTA) and United Kingdom (UK) and provides data residency in Germany with additional levels of control and data protection. You can also sign up for a free Azure Germany trial.
Premium Unmanaged Disks and page blobs
Premium Unmanaged Disks are high performance Solid State Drive (SSD)-based storage designed to support I/O intensive workloads with significantly high throughput and low latency. With Premium Unmanaged Disks, you can provision a persistent disk and configure its size and performance characteristics.
The total cost of Premium Unmanaged Disks depends on the size and number of the disks and will be affected by the number of outbound data transfers. These disk sizes provide different input/output operations per sec (IOPs), throughput caps, and monthly price per GB. You choose the option which best meets your required storage size, IOPs, and throughput. Attach several persistent disks to a virtual machine and you can configure up to 64 TB of storage per virtual machine, and achieve 80,000 input/output operations per second, and 1,600 MB-per-second disk throughput per virtual machine at less than one millisecond latency for read operations. Premium Unmanaged Disks are supported by DS-series, DSv2-series, FS-series, and GS-series virtual machine sizes which are specifically targeted for Premium Disks.
Snapshots are charged at $-/GB per month.

Standard Unmanaged Disks and page blobs
Standard Disks use Hard Disk Drive (HDD)-based storage media. They are best suited for dev/test and other infrequent access workloads that are less sensitive to performance variability.
The total cost of Standard Unmanaged Disk storage depends on the size and number of disks, the number of transactions, and the number of outbound data transfers.
|First 1 TB/Month||$- per GB||$- per GB||$- per GB|

We charge $- per 10,000 transactions for Standard Disks and page blobs. Any type of operation against the storage 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.
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.
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.
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.
