Which Oracle Cloud Infrastructure storage platform is used by MySQL Database Service for all data storage?

The "MySQL Database Service" on OCI uses "Block Volume Storage" (D) for all data storage, providing

high-performance, persistent block storage attached to compute instances for database operations.

"Object Storage" (A) is for unstructured data, "Flash Local Storage" (B) is temporary and instance-

specific, and "File Storage" (C) is for shared file systems—none suit MySQL’s needs. Oracle’s MySQL

Service documentation confirms Block Volume as the standard.
