Managed Disk vs un managed Disk

• Un managed disks have account limits in terms of TB (500 TB in as storage account)
• In Managed disks upgrading from Standard to Premium is seamless. (For unmanaged disks => Create a new storage account in premium tier, copy the VHDS to the new storage account and link it back to vm)
• A Managed disk will have a predictable performance. In the case of unmanaged disks only premium storage gives you predictable performance. There are IOPS limits of 20000 IOPS for the storage account.
• Managed disks have better availability SLA’s
