 objects (like storage classes).
 
 The downsides are:
-- Some attributes (driver name, topology) must be stored multiple times
+- Some attributes (storage class name, topology) must be stored multiple times
   compared to a more complex object, so overall data size in etcd is higher.
 - Higher number of objects which all need to be retrieved by a client
   which does not already know which `CSIStorageCapacity` object it is
