* Encryption at-rest ([Azure Storage Service Encryption](../common/storage-service-encryption.md?toc=%2fazure%2fstorage%2ffiles%2ftoc.json)): Storage Service Encryption (SSE) is enabled for all storage accounts. Data at-rest is encrypted with fully-managed keys. Encryption at-rest does not increase storage costs or reduce performance.

* Optional requirement of encrypted data in-transit: when selected, Azure Files rejects access the data over unencrypted channels. Specifically, only HTTPS and SMB 3.0 with encryption connections are allowed.

For maximum security, we strongly recommend always enabling both encryption at-rest and enabling encryption of data in-transit whenever you are using modern clients to access your data. For example, if you need to mount a share on a Windows Server 2008 R2 VM, which only supports SMB 2.1, you need to allow unencrypted traffic to your storage account since SMB 2.1 does not support encryption.

## File share performance tiers

Azure Files supports two performance tiers: standard and premium.

* **Standard file shares** are backed by rotational hard disk drives (HDDs) that provide reliable performance for IO workloads that are less sensitive to performance variability such as generalpurpose file shares and dev/test environments. Standard file shares are only available in a pay-as-you-go billing model.

-
* **Premium file shares (preview)** are backed by solidstate disks (SSDs) that provide consistent high performance and low latency, within single-digit milliseconds for most IO operations, for the most IO-intensive workloads. This makes them suitable for a wide variety of workloads like databases, web site hosting, development environments, etc. Premium file shares are only available in a provisioned billing model.

### Provisioned shares

-
Premium file shares are provisioned based on a fixed GiB/IOPS/throughput ratio. For each GiB provisioned the share will be issued 1 IOPS and 0.1 MiB/s throughput up to the max limits per share. The minimum allowed provisioning is 100 GiB with min IOPS/throughput. Share size can be increased at any time and decreased any time but can be decreased once every 24 hours since the last increase.

On a best effort basis, all shares can burst up to 3 IOPS per GiB of provisioned storage for 60 minutes or longer depending on the size of the share. New shares start with the full burst credit based on the provisioned capacity.

Today, the maximum size for an Azure file share is 5 TiB. Because of this current limitation, you must consider the expected data growth when deploying an Azure file share. Note that an Azure Storage account, can store multiple shares with a total of 500 TiB stored across all shares.

It is possible to sync multiple Azure file shares to a single Windows File Server with Azure File Sync. This allows you to ensure that older, very large file shares that you may have on-premises can be brought into Azure File Sync. Please see [Planning for an Azure File Sync Deployment](storage-files-planning.md) for more information.

There are many easy options to bulk transfer data from an existing file share, such as an on-premises file share, into Azure Files. A few popular ones include (non-exhaustive list):
