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 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.
