Difference between block storage and persistent volume

Is there a difference between DO’s block storage and a standard persistent volume in k8s? based on my reading it seems there is. SO for example if I add a PV using the following config:

apiVersion: v1
kind: PersistentVolume # Create PV
metadata:
  name: postgres-volume # Sets PV name
  labels:
    type: local # Sets PV's type
    app: postgres
spec:
  storageClassName: manual
  capacity:
    storage: 2Gi # Sets PV's size
  accessModes:
    - ReadWriteMany
  hostPath:
    path: "/data/postgresql" # Sets PV's host path

And then proceed to delete the Node then this PV will also be deleted right? But if I was to create the PV using DO’s block storage, would that persist even if node was destroyed?

i.e with:

apiVersion: v1
kind: PersistentVolume # Create PV
metadata:
  name: postgres-volume # Sets PV name
  labels:
    type: local # Sets PV's type
    app: postgres
spec:
  storageClassName: do-block-storage # DIFF HERE
  capacity:
    storage: 2Gi # Sets PV's size
  accessModes:
    - ReadWriteMany
  hostPath:
    path: "/data/postgresql" # Sets PV's host path
