I am still using an external Western Digital Enclosure with a Thunderbolt 1 connection as an off-site storage device that uses HFS+. It requires an adapter to work with M-series Macs. When I bought it, 4 TB was a lot of storage, and I had no idea that Apple would abandon the Thunderbolt 1 port.


All my internal and external SSDs use APFS. I just don't see any advantage to converting the WD storage device to APFS.

APFS was designed for SSDs. It will work on spinning disks, but there will be performance problems.

Use HFS+ for spinning disks and APFS for SSDs.

An earlier article talked about how APFS affects HDD performance in a long term of use.


I have several HDD for cold backups and Time Machine. All of them are on HFS+.

I still use HFS+ on any and all drives where it's use is "not required" by the OS.

The OS requires that you use APFS on
- boot drives
- time machine backups (I don't use tm)
- CarbonCopyCloner and SuperDuper cloned backups.

BUT... on EVERYTHING else, I still use HFS+.
On SSDs and HDDs.
I'll continue to use it, so long as I can still do so.
I guess that's just me.
 
There simply aren't any great tools to repair APFS issues so i stick to HFS+ and use DiskWarrior to repair all issues when they arise. Not to mention full clones are easy with HFS+. My Mojave is rocking a 4 x 400GB RAID HFS+ startup drive.
 
rin chided me with:
"The drive itself can carry other partitions with other formats."

Heh.
I'm the only Mac user you will ever meet who has hard-partitioned an m4 Mini internal SSD into four user partitions (not including the sealed system volume, etc.):
- Boot (APFS)
- Main (HFS+)
- Media (HFS+)
- Music (HFS+)
