 //CNV-7170 - CDI import of container disks is faster and more efficient
+* The Containerized Data Importer (CDI) can now import containerDisk storage volumes from the container image registry at a faster speed and allocate storage capacity more efficiently. CDI can pull a containerDisk image from the registry in about the same amount of time as it would take to import from an HTTP endpoint. You can import the disk into a PersistentVolumeClaim (PVC) equal in size to the disk image to use the underlying storage more efficiently.
