Azure Files offers serverless file shares, accessible via the industry standard Server Message Block (SMB) and FileREST protocols. Azure file shares can be mounted concurrently by clients in Azure VMs or from on-premises workstations running Windows, macOS, and Linux. Additionally, Azure File Sync allows caching and synchronization of Azure File shares on Windows Servers for local access.

Tier Description
Premium Premium file shares enable highly I/O-intensive workloads, with high throughput and low latency. Premium file shares are offered on high-performance solid-state drive (SSD) based storage.
Transaction optimized Transaction optimized file shares enable transaction heavy workloads that don’t need the latency offered by premium file shares with consistent latency. Transaction optimized file shares are a great fit for applications that require file storage or for backend storage.
Hot Hot file shares offer storage optimized for general purpose file sharing scenarios such as team shares and Azure File Sync.
Cool Cool file shares offer cost-efficient storage optimized for online archive storage scenarios. Azure File Sync may also be a good fit for lower churn workloads.

Premium file shares are available through the FileStorage storage account type. Pricing for premium files shares is based on provisioned GiB, and includes all transaction costs. You can configure your premium shares based on your storage size, IOPS, and throughput requirements. To learn more, see understanding provisioning of the premium file shares.

Standard file shares are available in general purpose storage accounts. General purpose v2 storage accounts offer the latest Azure Files features, including hot and cool tiers and are recommended for all users. Transaction optimized file shares are available in both general purpose v1 and v2 storage accounts. Pricing for standard file shares is based on usage, such that base storage and transaction costs are billed separately.

* Provisioned size of a premium file share is specified by quota on the shares. If you decrease the provisioned shares size below the used GiB, you will be billed for the used GiB on premium shares. To learn more, see understanding provisioning of the premium file shares.

** The hot and cool tiers are currently available in a limited subset of regions. Please see Hot/Cool region availability for more information.

Soft-deleted file shares are always billed based on used rather than provisioned GiB. Soft-deleted standard file shares are billed at the same rate as live shares. Soft-deleted premium file shares are billed at the snapshot rate. Learn more about soft delete.

Transactions and data transfer prices

For both SMB and REST operations, transaction costs are incurred against your Azure file share, covering operations such as enumerating a directory or reading a file. These prices vary based on the redundancy option you select.

Prices marked as N/A indicate that the redundancy option is not available in the selected region. Note: File operations that result in data transfer outside of an Azure datacenter will incur additional outbound data transfer charges.

Prices marked as N/A indicate that the redundancy option is not available in the selected region. Azure File does not support read-access geo-redundant storage (RA-GRS) in any region at this time. File shares in the RA-GRS storage account are charged at GRS prices. Note: File operations that result in data transfer outside of an Azure datacenter will incur additional outbound data transfer charges

File Sync Prices

These are the costs of syncing your files from Windows servers to Azure file shares in the cloud. Learn more about Azure File Sync.

The total cost of Azure File Sync services is determined by the number of servers that connect to the cloud endpoint (Azure file share) plus the underlying costs of Azure Files (including storage and access costs) and outbound data transfer.

Below is the fixed monthly fee per server.

Price per month
Sync Server* $-

*One sync server free per storage sync service. Sync uses file operations to sync your data to the cloud and other servers, and you will be billed for any operations that are generated in the sync process. The number of file operations generated and the access costs scale with the number of file changes on the server and the number of servers that need to be kept in sync.
