d:\ drive (2x1TB SATA RAID 1 using ICH10R), actually I am still researching why the squential R/W is so slow. I have refreshed the most updated BIOS and drivers from ASUS, but the results make no differences. I am still asking myself, is chipset RAID 1 really so slow or just because of my special case??
