It gives no support to the Fusion drives.

Compression is not allowed on an APFS drive.

The APFS drive is generally more stable and reliable than the previous HFS+ or HFS drive.

This helps to reduce storage space greatly when users copy files, make revisions, or do other things.

The clones or multiple copies of the same file are allowed it will only store the changes as deltas.
