Managed Disks

Persistent, secured disk storage for Azure virtual machines

Simplified Management

Create Managed Disks by just specifying the type of Storage (SSD or HDD) and the size of the disk you need, and Azure will create and manage disk for you.

Scalable VM deployments

Create thousands of Managed Disks simultaneously in minutes, in a single Azure subscription. Create up to 1,000 virtual machines in a single scale set to deploy a single large cluster, for example a large-scale HADOOP or DataSynapse deployment.


Apply granular access control on your Managed Disks using Azure RBAC. Managed Disks expose variety of operations such as read, write (create/update), delete, export. Grant access to only the operations that a person needs to perform his job.

Highly durable and Available

Provides industry leading durability and availability by simultaneously replicating your data to three different replicas. If one replica experiences issues, two others can take over to help ensure persistence of your data and high tolerance against failures.

Multiple storage options

Choose SSD based Premium Managed Disks for production and performance sensitive workloads where low latency and high throughput are critical. Use HDD based cost-effective Standard Managed Disks for Dev/Test or non-critical workloads.

Easy Migration

Easily migrate your Standard Managed Disks to Premium Managed disks with a single reboot. Also, migrate your existing ARM VMs with Unmanaged Disks to Managed Disks with a single reboot. As a virtual machine is migrated in minutes, schedule the migration during a pre-existing maintenance window.

Migrate to Managed Disks

Point-in-time backup

Back up your Managed Disks as point-in-time snapshots (copy). These snapshots can exist independently of the source disk and be used to create new Managed Disks later.

Simple Custom image management

Create a managed custom image from your custom VHD or from running VMs. Use the custom image to create multiple virtual machines or multiple large scale sets in the same region.


Encrypt your data using Azure Disk Encryption with Customer-managed or Microsoft-managed keys.
