Could you point me to a benchmark or comparison between plain software RAID and RAID using onboard controler (HPT, PRomisse, etc)??
thanks for your attention,
AMD 1.2, ASUS A7V133,"Promise Fasttrack 100" onboard controller (PDC 20265) in RAID0, 64k, using the ataraid driver (0.03beta), and two MAXTOR 7200rpm disks with 2MB cache
Here are my results. They are very poor. I wouldn't recommend the same stuff.

Anyone has results with software-RAID?
