Name the offenders please.

I am sure it might be easy to see visually - a lack of substantial capacitor on the board would indicate a high likelihood of data loss.

I'd be curious how well it actually correlates. It would be hard to make the most performant system that's always consistent with flushed data but there are probably a lot of firmwares out there with untested performance ideas, etc.

None of the tested drives use power loss protection capacitors.

    We're talking about scenarios where the drives report (untruthfully) that the data has been committed to non-volatile storage _before_ the power is removed

    Not scenarios where the data is in the cache when the power drops and the drive is expected to write out the cache with internal power alone.
