Azure Virtual Machine Disk Types

Choose the optimal storage for your virtual machines.

Ultra Disk

High Performance, Low Latency

Designed for I/O-intensive workloads that require consistent, low-latency performance. Ideal for mission-critical applications, large databases, and high-transaction environments.

  • Max IOPS: Up to 125,000
  • Max Throughput: Up to 2,000 MB/s
  • Latency: Sub-millisecond
  • Use Cases: Mission-critical applications, SAP HANA, large RDBMS

Premium SSD

Balanced Performance and Cost

Offers high-performance, low-latency solid-state drive (SSD) storage for I/O-intensive workloads. A great choice for most production workloads including dev/test, small/medium databases.

  • Max IOPS: Up to 20,000
  • Max Throughput: Up to 1,000 MB/s
  • Latency: Single-digit milliseconds
  • Use Cases: Production applications, dev/test, small/medium databases

Standard SSD

Consistent SSD Performance

Provides consistent and reliable SSD performance at a lower cost. Suitable for web servers, lightly trafficked production applications, and environments where performance variability is acceptable.

  • Max IOPS: Up to 1,000
  • Max Throughput: Up to 125 MB/s
  • Latency: Low to single-digit milliseconds
  • Use Cases: Web servers, low-traffic apps, dev/test

Standard HDD

Cost-Effective Bulk Storage

Offers the lowest cost for persistent disk storage, ideal for large volumes of data that are infrequently accessed. Suitable for backups, disaster recovery, and large-scale analytics.

  • Max IOPS: Up to 500
  • Max Throughput: Up to 60 MB/s
  • Latency: Tens of milliseconds
  • Use Cases: Backups, disaster recovery, archives
