I would expect 100MB/Sec average at least, even if on PCI Bus nevermind PCI-E bus.

Any ideas why its so slow
Thought I might mention that every now and then one of my hard drives makes a clicking noise. It doesnt do it all the time but I would say on average every 20 mins or so.
I am assuming this is not normal hence POSSIBLY the reason my RAID0 is so slow. However I dont get any errors showing anywhere not that I know where to look even if I did

That's very, very slow - slower than a single drive in fact.
For starters check the usual suspects - latest drivers installed, NCQ off, nothing odd showing in device manager.
Have you tried HDTach to see if that gives a similar result?
EDIT: If one of the drives is struggling then that might explain things but the Seagate diagnostics won't work while the drives are in a RAID array so unless you can easily break the array testing is going to be a pain.

I originally used a RAID0 using 2 x 7200.9's and this was fine although on a P5WDH-Deluxe.
I had a single 7200.10 which seemed fine and then I decided to buy a 2nd and have recently set them up in RAID0.
All this on my new board P35C-DS3R
EDIT:
This is the same on HDTach
I also have 2 x 7200.9's running in RAID1 in the same PC and this is was HDTach shows:

OK, those HDTach traces say a few things:
1) The .10s are definitely in RAID0 from the capacity markings on the graph
2) It's not just HDTune being wacky, the speed is low
3) Your RAID1 array is running nicely (irrelevant I know)
The only thing I can think of at this point is nuking the array and starting again but that'll be a pain if you have anything on it.

Guys,
In the Intel Matrix Storage Manager I put the 'Volume Write back cache Enabled to 'Yes' and my speeds go up a heck of a lot (should it be on or off)
Look at the burst rate and CPU usage is this normal

Firmware? Didn't put any firmware on? Is there some I should use then?
Board = Gigabyte P35C-DS3R
My drives are 250's mate
Intel raid controller Orange ports on board) as the pants purple Gigabyte ports wouldn't let Vista boot correctly!
Just tweaked some bits, look at my burst rate now?

That's looking not bad now, the daft burst rate seems to be a feature of the Intel controllers. I wouldn't worry too much about the wacky shape of the HDTach trace, the short bench occasionally does that. The long bench will give a better shape.
Oh this doesn't look good? I have Intel Matrix storage manager installed?
Should I have something else installed?
Come to think of it when I installed Vista it didn't ask for raid drivers it saw the single 500gb raid0 setup and I just installed it? Can I do a repair with the dvd and add the drivers in now do you think

tweakinfreak did you put the intel RAID drivers onto a USB stick or floppy when you installed Vista. When you get to the part where it says what disc you want to install Vista on there is an option that says additional drivers, do it then.
As a second note anyone concerned about one of my hard drives clicking, see above post. I would rather sort it out now than leave it.
Advise please.
No I realised yesterday that I didn't load the drivers 
it saw the 500gb raid0 so I thought great I will load Vista.......doh
I now know I need to get the drivers on, not sure how though as they won't load from windows?
Maybe do a repair from the Vista DVD and see if I can put them on?
Does my results look the right?

The speeds are correct for RAID0 and it's seeing 2x250Gb as a single 500Gb disk so there are drivers installed although the fact that Device Manager is reporting a "Raid Controller" and not an "Intel IHC blah blah" suggests that the driver being used is a generic one.
You should be able to ge the latest version from Gigabyte and do an Update Driver from within Device Manager.
