I have a raid 0 with 2xsamsung F1 750gb using the fake raid on my mobo (Asus maximus formula). This is my first time installing raid so I need some tips to optimize it or set it up correctly. I am using windows vista 64 bit and installed intel matrix storage console 7.0.0.1020. Then I have used HD tune to check if I am getting decent result but I don't understand is why it starts so low and go up. The pictures I have seen on Internet usually starts high up. Is there anything wrong with the result?

I wonder if its safe to write-back cache enabled as you do get better result but as I have read it might not be safe to use it. Is anybody using this option for their raid? The result which I have achieved from write-back cache enabled is shown below.

The other thing is that intel matrix storage console is showing some other controller then Intel ICH9R. Do I have to install some correct drivers or?

The reason for the weird spikes is that you're testing out the array on an OS partition - while you're doing the test, there's probably other processes running in the background doing a bit of disk I/O, virus scanners or antivirus scanners running in the background, Windows Defender/Security Center suite doing a routine scan, or maybe Vista is indexing files in low priority - any one of these would affect your results.

Short story: no, nothing seems to be wrong with your array other than that you're testing it on an OS partition. IF you wanted best results, do the test from another OS partition and boot it up from there, but doing that much effort just for a benchmark isn't really worth it, now is it? ;)
 
I haven't messed around with Intel RAID driver software before, but I would imagine there'd be no issues unless you installed the wrong driver.

ICH9R just refers to the name of the Southbridge, not necessarily the RAID controller built into the Southbridge itself, despite the "R" in "ICH9R" standing for "RAID".
 
everything I find on the 82801HR/HH/HO references the ICH8R IO controller, not the 9R. What board do you have, and have you looked at the manual, or downloaded it to confirm what you should have? It's extremely likely that you've got what your supposed to have, and it's just being reported wrong in the Intel Matrix storage manager.
 
I suppose its right as in everest its named Intel 82801IR ICH9R and my motherboard is asus maximus formula (as stated already in the first post) and I am wondering if anyone can explain to me if its worth using write-back cache?
