storageType

The storage type to associate with the DB instance.

If you specify io1 or gp3, you must also include a value for the Iops parameter.

This setting doesn't apply to Amazon Aurora DB instances. Storage is managed by the DB cluster.

Valid Values: gp2 | gp3 | io1 | standard

Default: io1, if the Iops parameter is specified. Otherwise, gp2.
