6.1 APFS support, hard disks?

Hello,

For traditional hard disks in RAID 5 is HFS still preferred?

For reference I have 4 x 4TB hard disks in RAID 5 with two partitions. I have a 2TB partition for Time Machine which is APFS since that's the only way it would work, and a 10TB partition in HFS.

Thank you

APFS volumes are slower than HFS. Especially on HDD's after being used for a while. So we recommend HFS on hard drives. If performance is not critical, APFS does offer better robustness.

A used HDD volume can be 50% slower than HFS, for reference.

Can you describe the "robustness"?  In particular I've read that APFS is now the recommended format for Time Machine and wondering if APFS would significantly improve reliability of TM backups?  With the huge number of files, TM seems to cause havoc with the directory structure of HFS periodically.  Throughput isn't a big concern for me.  Thanks. 🙂

There is no longer a choice, all Time Machine volumes must be case sensitive APFS.

APFs has directory robustness, but as of yet, no repair tools if something goes wrong. There are tools for recovery, which are of modest effectiveness on SSD media. So on the one hand, APFS is more reliable, but on the other, keep your active backups, as problems are possibly terminal.
