I have a system that uses drives on all channels, eg master/slave.

in the same channel.
Yes it is slower, but for me performance is good enough.

With two drives per channel, doesn't a disk failure pull down the other
drive, causing the entire array to fail, and require a reboot to bring the
degraded array back online?

yes that is an additional failure mode possible when you use two ata
drives on a channel.  this isn't really a recommended configuration.

you might have to dork with raid superblocks to recover from such a
failure.  in fact chances are you *will* have to dork with raid
superblocks to recover.
