Bucket and Object Storage Types

When creating a bucket, you can specify its storage type. Once created, the storage type cannot be changed. However, you can change the storage type for objects within the bucket. If you require a bucket with a different storage type, consider creating a new one.

By default, when uploading an object to a bucket, its storage type aligns with that of the bucket. However, you can specify a different storage type for the object during the upload process or modify it manually afterward.
