Azure Managed Disks simplifies your storage management by removing the need to separately manage storage accounts. You can also migrate your existing Azure VMs to Managed Disks to benefit from better reliability of VMs in an Availability Set. It ensures that the disks of different VMs in an Availability Set are sufficiently isolated from each other to avoid single point of failures. It automatically places disks of different VMs in an Availability Set in different Storage scale units (stamps) which limits the impact of single Storage scale unit failures caused due to hardware and software failures. Based on your needs, you can choose from four types of storage options. To learn about the available disk types, see our article Select a disk type
