More on APFS

Although it will not be fully implemented until MacOS 13 (Sierra's successor) APFS could be a real game changer for utility developers not to mention users. If I understand correctly...
  • APFS appears to be optimized for SSD/flash storage but apparently it will work on spinning rust as well. (I wonder if APFS will impose an additions performance hit on spinning rust)
  • APFS provides multiple levels of encryption
  • different levels of encryption for individual folders and/or files.
  • files are broken up into fragments and those fragments are located on the drive randomly
I can't imagine there would not be backward support for HFS+ in MacOS 13, but maybe not in MacOS 14?

In any case it is dead certain Alsoft (DiskWarrior), Micromat (TechTool Pro), and Prosoft Engineering (Drive Genius) will have their work cut out what tools will be needed and developing support for APFS. I would be surprised if some pf their tools/functions were dropped entirely and others may have to be redesigned and recoded from scratch.

If we knew what it was we were doing, it wouldn't be called research, would it?
