CCC blog on APFS Hard Drive Performance and Degradation
The Carbon Copy Cloner blog has an article titled An analysis of APFS enumeration performance on rotational hard drives that details the much slower performance of APFS formatted Hard Drives vs SSDs, and how that performance degrades quickly. Here's a short clip:
"I'm convinced that Apple made a fundamental design choice in APFS that makes its performance worse than HFS+ on rotational disks. Performance starts out at a significant deficit to HFS+ (OS X Extended) and declines linearly as you add files to the volume. ...

APFS takes three times as long to enumerate a million files on a rotational disk compared to HFS+ enumerating the exact same collection of files on the exact same hardware. This result on its own is staggering. As you add and remove files from the volume, however, the performance continues to decline. After just 20 cycles, APFS enumeration performance is 15-20 times worse than HFS+ performance."

The article has in-depth analysis and graphs. A must read for anyone using APFS boot HDDs.
