Hi,
It is recommended to use storage with the new pricing model in case the legacy storage model is terminated.
You can use some strategies to reduce your own storage costs, such as deleting long-term invalid data.
If you still want to use the legacy storage model for storage, you must pay attention to the official statement to prevent losses.
If this helped you, I'd appreciate it if you'd mark this as a Verified Answer, which may in turn help others as well.
Best Regards,
