I just got an Asus Rampage Formula setup with a Q6600, 2x 2GB Patriot DRR2 1066 5-5-5-15, and an HD4870, but one of my raid 0 arrays seems incredibly slow, these drives were not this slow on their previous RAID controller.

Drive configurations:

OS_Install: 2x 36.7GB Raptors RAID 0 (Seems to be getting average performance, but looked kinda choppy)

Apps_Install: 2x 250GB WD Caviar RAID 0 (Extremely slow, only getting about 20mb/s at most)

Main_Storage: 1x 500GB WD Caviar
Media_Storage: 1x 500GB WD Caviar

The OS_Install array seems okay but not great, but Apps_Install is outrageously slow, something is definitely wrong. Main_Storage and Media_Storage seem fine as well.

These pictures should give you a better idea of my configuration:

Thanks.
 
Also, both of these arrays were setup in the BIOS through the ctrl+i menu, I also noticed that they are set as basic disks in windows, shouldn't they be dynamic? If I need to change them to dynamic that means reinstalling everything. Plus how am I going to set the System disk to dynamic? I don't get that option when installing windows. I'm confused.
 
You're using fake-raid... it will show up as a single disk to Windows... basic disk is fine...

You can try turning on write-back cache... although beyond that I dunno what to say, my 2 x 36 raptors in Raid0 were great on my ICH9R...

I think I have it solved, I updated to the newer 8.2 version of the Intel Matrix Storage Console/Driver and all seems well. The version Asus included was 7.x, and was probably really old.

Thanks for your thoughts.
