In the past, it was best to have a UPS. That was long ago, and was largely because (PATA/SATA) drives would lie about completing writes. In which case, you disabled the write cache. Which was also something that should have been done if you were using any kind of software raid. Now that we have write barriers, it's a non-issue. Also having a battery-backed or flash-backed write cache on your raid controller was a non-issue (assuming your raid controller is smart enough to turn off each drive's write cache). /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
