> Because of performance, especially regarding being able to use a battery-backed write-back cache on the controller to give a "safe in the event of powerfailure" confirmation to the application before it actually hits disk/flash. Is this not easily mitigated with a smart UPS? (i.e., one that will notify the host when the battery is low so it can shut down cleanly)
