From the system logs I glanced over and saw this message regarding the
vendor's raid feature.

Is the community consensus to turn off all vendor raid feature added
tools?
RAID is useful, some use it, some not, depends from case to case. I for

times, like switching from write-back to write-through in some scenarios
and hitting me hard performance-wise).
