Disk storage

Persistent, highly secured disk options that support virtual machines

Whether you’re running mission-critical applications or working with test scenarios, Azure Disk Storage provides the durability, availability and security you need for your virtual machines. Choose Premium Disk Storage (SSD) for I/O intensive applications, where low latency and high throughput are critical. Select Standard SSD for entry-level production workloads that demand consistent performance—or use as a cost-effective solution for development and testing scenarios.

Simple management

Create a managed disk by specifying the type of storage and the disk size you need. Then, Azure Storage will create and manage it for you.

Managed disks overview

Highly durable, available and secured

Azure Disks are designed for 99.999% availability. Rest easier knowing that you have three replicas of your data that enables high durability. If one or even two replicas experience issues, the remaining replicas help ensure persistence of your data and high tolerance against failures. This architecture has helped Azure consistently deliver enterprise-grade durability for IaaS disks, with an industry-leading 0% annualised failure rate. Plus, your data is automatically secured using encryption at rest.

Why choose Azure Disk storage?

All cloud disk storage is not the same. Azure offers you:

Simple scaling on demand

Migrate your on-premises enterprise application to the cloud, and walk away from the hardware and infrastructure management. Scale storage up or down with your virtual machine whenever you need to, and absorb unexpected spikes in traffic or any growth in data storage size. Lift and shift your entire infrastructure model, on Windows or Linux, and get highly scalable, globally available cloud storage.

Low-latency and high-throughput storage

When performance is critical, you want the low latency and high throughput of Premium Disk Storage (SSD). Build your high-performance database with large Azure virtual machines (GS-series), and you’ll get the speed that’s needed for enterprise workloads. Maximum disk throughput per virtual machine is up to 80,000 IOPS and 2,000 MB per second – and it’s even faster with caching.

Premium Storage overview

Low-cost and consistent performance for all Azure VMs

Azure Standard SSDs are a cost-effective SSD offering – an Azure Managed Disk solution optimised for test and entry-level production workloads requiring consistent latency. Standard SSDs can:

  • deliver lower latency compared to Standard HDDs;
  • be used for big-data workloads that require high throughput;
  • improve reliability and scalability for your applications;
  • offer the same industry-leading durability and availability you expect from Azure Disk Storage;
  • be upgraded to Premium SSDs for more demanding and latency-sensitive workloads.

Standard SSD overview

"By upgrading to Azure Premium Storage for our Slim4 inventory control application, we halved processing time and gained the assurance that this critical application will run smoothly."
