Just to end this thread properly, we did find a suitable solution.

Turns out the RAID card was lacking a battery, and that was causing
performance issues with writes. Adding a battery fixed the performance
issue (of course, our battery checks check for a failed battery, not a
non-existent one).

I suspect the observed symptoms were a result of too long an input queue
caused by the queue consumer (idoutils) not being able to keep up.
