macOS High Sierra comes with a new file system APFS, now according to official notes APFS for now only supports modern SSDs.

My Mac runs on a traditional rotational hard drive and according to Apple macOS High Sierra 10.13.0. Apple recently released 10.13.1 and after updating to the latest version I booted into the recovery and after opening disk utility and going through the menu bar options I came across option know as convert to APFS, so my concern is that after the recent update has Apple finally included APFS support for traditional hard drives and should I convert my drive to the latest APFS filesystem

  • It works from the first 10.13 release, but is noticeably slower. I converted root partition to it because it solved 10.12 -> 10.13 update program crash in the middle of update. Now I'm using 10.13.4 and it feels much slower than hfs+ (although as RAM cache fills with data, it becomes fast). Not sure if they will solve this slowness on HDDs in future versions. – kolen Apr 12 at 22:59
