Disk Storage

Persistent, highly-secure, cost-effective SSD options to support your Azure Virtual Machines

Get HDD/SSD durability, scalability, availability, and security you need for all your workloads—from mission-critical workloads to test scenarios. Use Ultra SSD when you need sub-millisecond latency and extremely scalable performance; Premium SSD high-performance disk storage for production workloads; and Standard SSD for cost-effective and consistent performance.

Simplified management

Select the disk type and size needed for your workload, and Azure will create and manage the disks for you. Easily upgrade from Azure Standard HDD to Premium SSD as your requirements evolve.

Scalable disks for your virtual machines

Create thousands of managed disks simultaneously, in minutes, with a single Azure subscription. Use VM Scale Sets to deploy a single large cluster for your cloud-native workloads. Scale up your SSD storage capacity without compromising performance, using disk sizes up to 64 TiB.

More secure

Azure Managed Disks encrypt your data at rest, by default, using Storage Service Encryption. Control users’ level of access to your Azure disks with role-based access control (RBAC), and help protect your data with point-in-time backup.

Highly durable and available

Azure Disks are designed for 99.999-percent availability and have consistently delivered enterprise-grade durability with an industry-leading zero-percent annualized failure rate. Take advantage of our single instance virtual machine SLA of 99.9 percent with Premium Disks. Learn more.

The Azure Disk Storage advantage

Ultra SSD: sub-millisecond latency with ultra-scalable performance

For your most demanding, data-intensive workloads, Ultra SSDs deliver unprecedented and extremely scalable performance with sub-millisecond latency.

Support your digital transformation with disk storage ideally suited for next-generation, data-driven applications, such as: SAP HANA, SQL Server, transaction-heavy workloads, complex analytical modeling, gaming, rendering, and low queue-depth databases.

Premium SSD: high-performance disk storage for production workloads

When performance is critical, take advantage of the low latency and high throughput of Azure Premium SSD.

Premium SSDs represent a good fit for production workloads, such as SQL Server, Oracle databases, Microsoft Dynamics, Microsoft Exchange Server, MySQL, Cassandra, MongoDB, and SAP Business Suite.

Standard SSD: cost-effective and consistent performance

For a cost-effective disk offering that can work with any Azure VM, and that’s designed to provide consistent latency for low-IOPS workloads, deploy Standard SSDs.

Standard SSDs can support diverse workloads, such as web servers, low-IOPS application servers, lightly-used enterprise applications, and dev/test scenarios. Upgrade to Premium SSDs for more demanding and latency-sensitive workloads.

Standard HDD: low-cost storage for infrequent data access

Use Azure Standard HDD Managed Disks for noncritical workloads that require infrequent access to your data and when you don’t need production-level performance. Attach Standard HDD disks to any Azure VM to achieve cloud scale for your development and test scenarios, at cost-efficient price points.

Standard HDD Managed Disks can also be used for backup and archiving applications.
