## Virtual machine uncached vs cached limits
Virtual machines that are enabled for both premium storage and premium storage caching have two different storage bandwidth limits. Let's look at the Standard_D8s_v3 virtual machine as an example. Here is the documentation on the [Dsv3-series](dv3-dsv3-series.md) and the Standard_D8s_v3:

This section helps you to make the best decision on VM and disk types.

If you are planning on migrating from unmanaged disks to managed disks, you should be aware that users with the [Virtual Machine Contributor](/azure/role-based-access-control/built-in-roles#virtual-machine-contributor) role will not be able to change the VM size (as they could pre-conversion). This is because VMs with managed disks require the user to have the Microsoft.Compute/disks/write permission on the OS disks.
