I don't think Apple quite advertises it this way but as a matter of
practice HFS+ is still the preferred filesystem for any external

mentioned more prominently, in my experience, but that is really for
internal SSDs.

Linus Torvalds once described HFS+ as “complete and utter crap”
<https://www.zdnet.com/article/horrors-linus-torvalds-calls-hfs-utter-crap/>.

Did you know it cannot represent dates/times past 2040? 32-bit Linux
builds have already fixed their year-2038 problem; when is Apple going
to fix its equivalent?

I have a friend who put APFS on a spinning internal drive (while
working at Apple) with somewhat dated hardware and saw inferior
performance (to HFS+). He reported this to the guy who designed APFS
whose response was, "Of course." I have done modest testing of APFS
on external SSDs and it was markedly slower than HFS+ on the same
drive.

Interesting. In the Linux world, we run the same filesystems (e.g.
ext4) on SSDs as we do on spinning media. The SSDs are supposed to
have elaborate firmware to make them behave just like disks; does the
new Apple filesystem not interact well with this firmware?

Linux also offers specially-designed filesystems, with wear-levelling
built into their storage-allocation algorithms, so that they will run
efficiently on raw flash media.
