Virtualized data storage can improve storage resource utilization and system security and reliability

Non-virtualized data storage creates disk data faster and performs better than virtualized storage

Storage mounted by raw device mapping can only be created on disks of the same capacity as data storage, and does not support advanced functions of

virtualized storage
