I have heard reports that vinum woudl be faster than using the native card. Is this true? Should I not bother with doing the hardware raid and just go with vinum? The rest of the system is a k6-2 400mhz with 256mb ram (amount might change). I will also have moderate network i/o on the pci bus (obviously). TIA, cowbert -- Peter C.
