That just means you're using sucky hardware. We've been using h/w
controllers for 15 years, and never had a problem.
Of course, they are proprietary, and from a Tier 1 vendor, cost a
lot of money, and maintenance fees are high.
But we've never lost data from a controller failure. (And damned
little loss from any other reason, either, since there's a 24x7
admin staff that pays attention to drive failure lights, and
replaces them immediately.)

And that detailed care makes all the difference in the world! Now limp
along with a drive failure, add a controller that needs updating and
perform the update. Suddenly you find the meta data is "unstable" and
you can not recover from it. I have NOT seen data loss from a
professional, on the ball data center.
