Q: I'm trying to create a striped volume using 64 disks in Azure with a Windows virtual machine, but it's failing, showing 32 disks is the maximum; why?

A: Striped volumes using dynamic disks support only up to 32 disks, as explained in "Create a Striped Volume." However, if you're using Windows Server 2012 or later in Azure, you shouldn't create striped sets using dynamic disks but instead should be using Storage Spaces. Storage Spaces is the preferred option in Azure and supports up to 240 disks in Windows Server 2012 R2 (or 160 disks in Windows Server 2012). When possible, avoid using dynamic disks.
