+  An API object that represents a piece of storage in the cluster. Available as a general, pluggable resource that persists beyond the lifecycle of any individual {% glossary_tooltip term_id="pod" %}.
 long-description: |
-  Persistent Volume subsystem provides an API for users and administrators that abstracts details of how storage is provided from how it is consumed.
+  PersistentVolumes (PVs) provide an API that abstracts details of how storage is provided from how it is consumed.
+  PVs are used directly in scenarios where storage can be be created ahead of time (static provisioning).
+  For scenarios that require on-demand storage (dynamic provisioning), PersistentVolumeClaims (PVCs) are used instead.
