I converted a 1 TB drive (older model) to APFS to see what would happen. I didn't see any performance benefits. after about 1 month running on APFS the drive has irretrievably crashed. I can not even format or partition it anymore.
Got a tip for us?

Anyone had any issues copying large amount of data to a large RAID0 drive formatted to APFS? I've been copying 17Tb of data over a network share onto a 20Tb drive and my 10.13 has been kernel panicing every so often. Once within 60 seconds of starting the copy.
This is what I see in the kernel panic log:
Kernel Extensions in backtrace:
com.apple.filesystems.apfs(748.1.47)[136956FE-7D90-3242-A787-698B805F274F]@0xffffff7f8c6ea000->0xffffff7f8c7c0fff
Anyway, formatted it back to HFS+, initiated the copy and currently halfway through a 48 hour transfer and no trouble.

Hasn't apple said the whole time even on their support pages that AFPS is not for HDD's? SSD only.
I think their words were more along the lines of APFS being optimised for SSD, rather than HDD, but that doesn't mean it won't work perfectly well on HDD. Fusion drives create additional hurdles that Apple need to resolve.
I'm running three internal SATA drives and one external firewire drive with APFS. There have been no issues converting or using them, so the only drive still using HFS+ is Time Machine, because that doesn't support APFS.
