I have to second the raid10 proponents. Excellent redundancy, performance, and minimizes rebuild time--meaning you're back up to full redundancy that much quicker after a failure. It also maximizes the failure combinations you can withstand.
If you use the md raid10 driver, you can actually achieve near raid0 read performance (depending on layout choice and access pattern of course). You can also use the md raid0 on top of raid1 components. /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
