just use disk management in Windows...there maybe better programs...but the end result is the same.
Truth be told.. in the haste of my investigation I already set it once to RAID and it didnt work so I went back to the bios and set it back to ACHI... all seems to be still working..
(I havent yet tried your article yet).
Ok did the above and now Im in W7 with RAID on! Now to array the 2 drives.
Ok got the 2 drives raided but for some reason my benchmarks for the drive were the same as if they were unraided... whats the best testing software i should be using?

Sounds like good progress.
Essentially there could be a couple of reasons.
1. Your driver. Which one you installed? I know 8.8 ISM is pretty good. I use 9.6 RST (rebranded ISM) and things run ok. IT could be that you need to play around with different versions. Don't worry you can install over the top and it manages the uninstall ... nothing like ATI drivers! Im all honesty though I don't think this is going to make a difference of light and day. IF your not seeing any performance gains then it could be reason 2.
2. Your controller is already reaching the maximum bandwidth it can handle. This is very possible when working with SSD and onboard RAID controllers...do you know the throughput? If it is a ICH10R then the max read writes are around 600MB/s ... what do your SSDs run at independently?
ATTO seem to be the one people use. Crystal Disk Benchmark and AS SSD is ok too.

Well heres the wierd thing...
Using HD Tune Pro the performance was around 250ish.
Using ATTo, the performance was reaching above 500.
And using ATTO on my single non raid SSD, the performance was 250, so it seems the raid is double using ATTO but not using HD Tune pro.... any idea?
Also if I copied a file from and to the same Raid drive the transfer rate seems to be around 150mb/s. Surely it should be more?
Can't help you here... I have heard that HD Tune pro might not be as reliable..or perhaps that it is harder to do direct comparisons.
I would rely on ATTO (default settings) as the definitive answer. Try Crystal Disk Mark too...post result screen shots.
Well ATTO is showing things in the right perspective for sure... but I am just wondering about real word transfers.. For example.
I just transfered some files over and the read/write speed on the raid was coming up at around 140mb/s does this sound right?
Would it be quicker had I been transferring from one SSD to another?

hmm. where are you copying them from? A spindle disk.
It doesn't sound quite right. It does depend on the file sizes etc.
Ok well firstly I tried copying from a spindle disk to the RAID array. The size of the files we're in the order of around 10GB (about 5 of them).
The speed was around 140.
And then I tried recopying those same files on the RAID drive to another location on the same RAID drive...again same speed....
Not right?
