There is actually a website devoted to the "Battle Against Any Raid
'F'"...
http://miracleas.com/BAARF/
"The reason for BAARF is that we’ve had it. Enough is Enough. For 15
years a lot of the world’s best database experts have been arguing
back and forth with people (vendors and others) about the pros and
cons of RAID-3, -4 and -5. Cary Millsap has written excellent
articles on RAID technologies that should have stopped the use- and
pointless discussions many years ago. Many others have written
splendid articles about it as well. Many. James Morle and others have
written books where they discussed the uselessness of RAID-F stuff.
It has been the same arguments, the same mistakes, the same
misunderstandings that have guided the discussions for all those
years. The same frustrations from people that knew RAID-F is not a
good choice. The laws of Nature are still solidly in place and are
not going to be changed by RAID-F vendors anytime soon. So we’ve
decided to stop arguing and debating with people about it. We will
lower our blood pressure permanently by refusing to have any more
arguments about it."
