Wasn't APFS released with macOS Sierra? Now I'm really confused =/
APFS was included in sierra but technically speaking it was in beta state,
while you could create a hard drive partition and formatted using APFS in Sierra
but you can't create a bootable volume with APFS, install sierra and boot from it
while many people use commands at that time in sierra
i used Tuxera NTFS disk manager to access the hidden option and was able to create an APFS partition
at that time APFS was a bit faster than the old apple FS
but now is even faster than before because is no longer in beta state like it was back then in sierra
yes high sierra os is in beta but APFS is not in beta
now in high sierra you will be able to create a partition and format the drive in APFS and boot from it
so now is bootable
sorry for my bad english
i have 3 samsung 960 in raid0 hitting over 8,000 mbps or 8 gbps
and i need to order 1 more Samsung drive to have 4
i want 10,000 with APFS but most likely i will hit a little over 11,000
so just imagine how fast is going to be
even faster than my iram disk
