Disk Storage

Persistent, highly-secured disk options that support virtual machines

Whether you need the highest availability for mission-critical workloads, or cost-effective options for test scenarios, Azure Disk storage gives you 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. For testing, consider Standard Disk storage (HDD) to keep costs down, as you scale up and down quickly.

Simple management

Create a managed disk by specifying the type of storage (SSD or HDD) and the size of the disk you need, and Azure will create and manage the disk 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 which 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 ZERO% Annualized 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 growth in data storage size. Lift-and-shift your entire infrastructure model—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 your users can experience maximum disk throughput per virtual machine of up to 80,000 IOPS and 2,000 MB per second—and even faster with caching—the kind of speed you need for demanding enterprise workloads.

Premium Storage overview

Cost-effective testing

Support your DevOps goals and test workloads with simple cloud scalability, at a lower cost than on-premises. When you don’t need production-level performance, keep persistent data on Standard Disk Storage (HDD), and then spin up test virtual machines on demand.

"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."
