# Standard Clusters

If you choose the **Standard** option during cluster creation, data replication
in your cluster can be based on tablets (default) or vnodes, depending on
the configuration of your keyspaces.

When you [CREATE a keyspace](https://docs.scylladb.com/manual/stable/cql/ddl.html#create-keyspace-statement),
it has tablets enabled by default. To use vnodes-based
data replication, you must explicitly disable tablets when you CREATE a keyspace.
See [Enabling Tablets](https://docs.scylladb.com/manual/stable/architecture/tablets#tablets-enable-tablets)
in the ScyllaDB documentation for instructions.

A Standard cluster allows you to reach up to 70% storage utilization.
