poor raid 0 performance

[Hellfire260]

Hi Guys

I have the rdx200 cf-dr and i seem to get very poor performance
from my raid 0 setup using the sb450. In HDtach i only get aroud 22mb/s burst speed and an average read of 18mb/s.

Before i set up raid i used to get 79mb burst speed and 50mb average read.

Im am using 2x Western Digital 160gb sata 1 drives using 32k stripe

Does anyone know what is wrong and how it can be fixed.

Thanks

thanks for the help.

i downloaded the latest southbridge drivers and it now works

i get 125mb burst rate and 85 average read, it may not be the fastest but its quicker than my old setup
