No, Scott, that is not much of a problem. Even using software
raid, if one drive dies, the raid just fails the drive, and boots it out
and continues to run on the one remaining drive.
Its so smooth, you run the risk of missing the failure entirely.
When you add the new replacement drive, the raid just rebuilds
the array automatically.
I don't think any of the hardware raid controllers offer much
unless you are talking big enterprise level servers.
Software raid under linux is so reliable, and servers are
usually so un-loaded (cpu utilization hovering around 3%)
that the cost for the controller is better spent on ram.
