Get storage security and performance at scale

Shared disks

Attach a disk to multiple virtual machines (VMs) simultaneously to streamline app deployment or migration of clustered apps to Azure.

Performance tiers

Tailor throughput, use disk bursting, and select performance tiers to improve performance and cost efficiency.

Built-in security

Secure your data with automatic server-side encryption using platform-managed keys or, optionally, customer-managed keys.

Incremental snapshots

Minimize downtime, costs, and data loss and ensure business continuity by enabling cross-zone and cross-region disk copy.

Zone Redundant Storage (ZRS) disks

Enable disks to tolerate zonal failures, ensuring high VM availability while eliminating data replication across zones.

Backup and disaster recovery

Minimize disruptions, lower costs, and reduce time spent with point-in-time snapshots and solutions.

Customers are innovating with Azure Disk Storage


  • Data disks on Ultra Disk Storage hold up to 64 TB per disk. Data disks on Premium SSD, Standard SSD, and Standard HDD hold up to 32 TB. The number of data disks you can use depends on the size of the virtual machine.
  • Each of the five disk types differs in performance characteristics, so you can configure your storage based on your workload needs. Learn more
  • After you purchase a reservation, a discount is automatically applied to the disk resources that match the terms of your reservation. The reservation discount applies to disk SKUs only. Learn more about reservation discounts.
  • Bursting is enabled by default on new and existing deployments of the supported virtual machines and disks—no additional steps are required. Learn more about bursting.
