What is your reason behind getting real hardware RAID? From my own personal testing and online research, software RAID outperforms most real RAID cards. So if your reasoning is based on performance gain, you may be in for another shock. If your reasoning is so that you can multi-boot different OSes without requiring drivers, then you may have a compelling reason to go to hardware RAID. However, most cases fakeraid is good enough. -- Rick C. Petty
