This page explains how to create dynamic PersistentVolume resources that are backed by SSD persistent disks.
SSD persistent disks
By default, dynamically provisioned PersistentVolumes use the default StorageClass and are backed by standard hard disks. If you need faster SSDs, you can use the premium-rwo storage class from the Compute Engine persistent disk CSI Driver to provision your volumes. This can be done by setting the storageClassName field to premium-rwo in your PersistentVolumeClaim as shown in the following example:
# ssd-claim.yaml apiVersion: v1 kind: PersistentVolumeClaim metadata: name: my-volume spec: storageClassName: premium-rwo accessModes: - ReadWriteOnce resources: requests: storage: 30Gi To create the my-volume PersistentVolumeClaim object, use the following kubectl apply command:
kubectl apply -f ssd-claim.yaml When you create this PersistentVolumeClaim object with kubectl apply, Kubernetes dynamically creates a corresponding PersistentVolume object.
