Apple File System (APFS) I’ve seen @danj mention a new formatting method for SSD drives and know nothing about it. Is it used on hybrid drives, standard 2.5" drives, blades, logic board integrated drives, RAID arrays or a fusion set up? What are the benefits, drawbacks, when to use and not use? Where do I find this formatting utility, will it (or is it) in Sierra Disk Utility? Will it be in High Sierra? Is it to be on iOS devices and/or Macs? How is it an improvement over HFS+? Please, somebody teach us ;-)
So, I quickly pulled up the wiki page on this new file system, here, to get the basic idea. Then I found this page from Apple that goes into detail.
@mayer - I have it running on my 2011 27" iMac. I have a dual drive setup, boot drive is a Samsung 500 GB 850 EVO and a 1 TB Seagate HDD. The SSD is what is running APFS the HD is still running HFS+ gen3. It was very easy to update the drive to APFS. So far I’ve not had any issues with it running High Sierra Beta. I haven’t done any testing on it yet to see if it’s faster as I’ll wait till I get the gold release of High Sierra.
