I found that you run out of supported channels before you run out of
drive letters. When I tried to actually do some performance testing
(dd bs=4k if=/dev/zero of=/dev/hdX to lots of drives) I found the
performance dropped off rapidly with lots of simultaneous disk
activity. I chalked it up to running out of PCI-bus bandwidth, but I
don't really know.
