Yes, RAID is more complex and it's not fool-proof. RAID isn't supposed to have any data security beyond what entails from a single drive failure (or 2 with RAID 6). Lose one drive with RAID 1 or 5 and you've lost no data. If you have hot-swap drives, you can stay up through the drive replacement and array rebuild. The probability of failure of the RAID controller is also 100%, which is why admins sometimes have 2 or more RAID controllers on a system or have systems that can do bare metal restores of the OS and apps to another server, or they virtualize their servers to storage arrays (using RAID!). I've lost a RAID controller once. I've lost drives about a dozen times. RAID wins. <i>Jeff and I agree!</i> Rub it in whydoncha? Yes, RAID at home is usually overkill. ************************************************************************* ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *************************************************************************
