To ensure optimal speed, we recommend always using SSD disks to back your Rancher management Kubernetes cluster. On cloud providers, you will also want to use the minimum size that allows the maximum IOPS. In larger clusters, consider using dedicated storage devices for etcd data and wal directories.
