I would test how long a drive rebuild takes on a 20 disk RAID6. I
suspect, very long, like over 24 hours, assuming a fast controller and
sufficient channel bandwidth.

But isn't that one of the benefits of RAID6? (not much degraded/latency effect
during a rebuild, less impact on performance during rebuild, so longer times
are acceptable?)
