Choosing an Azure disk type

When you create volumes for ONTAP Cloud systems, you need to choose the underlying Azure disk type. Each disk type is designed for different workloads. You should choose the disk that meets your requirements for both performance and cost.

The underlying disk type for Azure can be Premium Storage or Standard Storage:

  • Premium Storage disks store data on solid state drives (SSDs). The SSD disks provide high performance for I/O-intensive workloads at a higher cost.
  • If you do not need high IOPS, you can limit your costs by using Standard Storage disks which are backed by hard disk drives (HDD).

For additional details about the use cases for these disks, refer to Azure documentation.
