storageClass property
The bucket's default storage class, used whenever no storageClass is specified for a newly-created object.
This defines how objects in the bucket are stored and determines the SLA and the cost of storage. Values include MULTI_REGIONAL, REGIONAL, STANDARD, NEARLINE, COLDLINE, ARCHIVE, and DURABLE_REDUCED_AVAILABILITY. If this value is not specified when the bucket is created, it will default to STANDARD. For more information, see storage classes.
