Q: Your company is migrating stateful MySQL databases to Docker. A consultant advises using "Bind Mounts". You disagree and advocate strongly for completely bypassing the Docker Storage Driver entirely by utilizing raw Block Devices. Why?

Using standard Docker Storage Drivers (like overlay2) or traversing file-system boundaries for massive, high-IOPS write-heavy database workloads introduces significant systemic overhead. While named volumes heavily bypass the UnionFS, for extreme enterprise database performance (bare-metal equivalence), you should allocate a raw LUN or dedicated partition (e.g., /dev/sdb) and map it directly into the container using the --device flag, allowing the database engine inside the container to interact directly with the kernel's block layer natively, completely eliminating Docker's storage abstraction penalties.
