I believe this has been discussed before, but I would like to bring it
up again.

I would like to see mdadm recommend RAID6 over RAID6 when using
component drives that are 500GB or larger and ask if the user is really
sure about using RAID5, plus a pointer to a webpage on the wiki
informing the user about the trouble with RAID5 on large volumes with
consumer or prosumer drives.

I am willing to contribute text to the webpage being pointed to.

Wikis change to regularly, too easily.  Networks can be down at times,
often the worst times.  See Murphy's Law.

It would be better to put this information in mdadm(8) and refer the
user there.
