Why My File System Used Space Increases After I Migrate from SFS Capacity-Oriented to SFS Turbo?

SFS Turbo file systems contain metadata, which occupies about 8% to 10% file system space. That is why the used space of your file system increases after a data migration from SFS Capacity-Oriented file systems to SFS Turbo file systems. The metadata consists of the file system management data, such as the file size, file system owner, and file modification time.
