Assembly: Microsoft.WindowsAzure.CloudDrive (in microsoft.windowsazure.clouddrive.dll)
A Windows Azure drive is a Virtual Hard Disk (VHD) stored in a page blob in Windows Azure storage. Each drive can be mounted as an NTFS volume in a role instance, and you can access a drive within your role by using standard APIs for accessing NTFS drives. All data written to a Windows Azure drive is immediately stored in persistent storage; your data is written before an application receives notification that the write operation has completed. A role instance can also transparently cache the drive data in local storage.
