Traditional volumes to store and retrieve data are created as Kubernetes resources backed by Azure Storage. You can manually create these data volumes to be assigned to pods directly, or have Kubernetes automatically create them. These data volumes can use Azure Disks or Azure Files:

- *Azure Disks* can be used to create a Kubernetes *DataDisk* resource. Disks can use Azure Premium storage, backed by high-performance SSDs, or Azure Standard storage, backed by regular HDDs. For most production and development workloads, use Premium storage. Azure Disks are mounted as *ReadWriteOnce*, so are only available to a single node. For storage volumes that can be accessed by multiple nodes simultaneously, use Azure Files.

In Kubernetes, volumes can represent more than just a traditional disk where information can be stored and retrieved. Kubernetes volumes can also be used as a way to inject data into a pod for use by the containers. Common additional volume types in Kubernetes include:
