- an individual virtual machine failure might destroy all the data
- no storage costs and are free.
Managed disks
- stored as page blobs

benefit:
- Simple scalability
- High availability
- Integration with availability sets and zones
- Support for Azure Backup
- Granular access control: Azure role-based access control (RBAC)

-

- OS disk: OS disk has a maximum capacity of 2,048 GB.
- Data disk
- number of data disks you can add depends on the virtual machine size.
- Each data disk has a maximum capacity of 32,767 GB.
