If your writes are so heavy to the point that you no longer benefit from the fast write cache, then I would stick to mirrorred non-raid, otherwise Raid would be a good choice since you would get fast throughput together with parity backup. A lot less costly than 2x disk when using non-raid mirroring. -- +----------------+ | Dave K. Lahoti | == D4kLaho@PacBell.COM --- http://www.PacBell.COM +----------------+
