raid5

Hi,

I build a computer with a raid5, using the motherboards raid controller (ASUS P7H57D-V EVO - intel Rapid Storage Technology). The read and write are however very slow, when using the raid controller :( - I am using Windows 2008 R2, and when using the windows software raid, it was ok in speed - so there must be an issue with the controller? Im using 6 disks on 2TB each.

Do anyone have any idea why its so slow, and how to fix it? I rather not pick the easy solutiuon of "just buy a raid controller" :|

If you need more info about my setup, please just ask.

Thanks :)
