=OpenEBS LocalPV=

Best for: Single-node clusters requiring features like snapshots, backups, or multi-disk management<ref>https://openebs.io/docs/quickstart-guide/installation</ref>.
Why:

* Extends local storage with enterprise features.
* Supports ReadWriteOnce (RWO) and integrates with Velero for backups.
