Over hardware raid? Never; hardware raid is always better than software raid (but is always more expensive too). If you're asking which of ccd and vinum is faster, I don't know. Try both and tell us :) - You misunderstood. I am planning to do a Hardware Raid 5 with each shelf giving 3.5TB of disk. Then I need to put a Raid 0 stripe across the 3 shelves with software to give me the ~10TB filesystem. For this which would be better... ccd or vimum? -Max
