Ok so i reinstalled my vista64 in raid expecting to see an increase in my importing speed.
Before i was importing >100 h/s, now it is about 40 h/s.
Is it possible i have done something wrong in the installation proces?
specs:
Intel Core 2 Quad Q9550 / 2.83 GHz processor
ASUS P5Q - motherbord - ATX - iP45
Samsung SpinPoint F1,7200RPM, SATA II, 16MB
Any thoughts much appreciated

-1 Which RAID chip is on your motherboard?
If you have a Intel ICH10x chip install the Intel Matrix Storage Console 8.9 and enable volume write back cache
-2 In the Power Options of your computer, set it to HIGH PERFORMANCE
-3 In the Advanced System Options--> Device Manager--> Enable write caching
-4 Do a CrystalDiskMark 2.2 benchmark of the RAID drive and post the scores here.

I will forward this to our resident hardware expert.

Thanks for your reply.
1- Its the ICH10R. I downloaded Intel Matrix Storage Console 8.9, write-back cache was enabled.
2- checked this, was already set.
3- checked this, was enabled.
4- seq read= 160.5 , write 167.4
512k read= 43.56 , write= 101.1
4k read= 0.635 , write= 5.898
I did some new imports, somehow the speed is up to about 70 hands/s.
Not as high as before raid-0 though.
There are 2 things worth mentioning; when i open the intel matrix storage console, and rightclick on an individual raid port (1 of the 2 samsung disks) the console freezes and i receive a windows message that the console needs to close.
2- when installing the raid drive, i was never asked to install any raid drivers.

The RAID driver should be a firmware driver already preinstalled on your mainboard. Intel rarely releases updates for it.
You have really nice (high) seq/512K write speeds! Those will be great for video editing. However, the import speeds are mostly controlled by 512K/4K read speeds, and there's not much difference with your RAID0 setup compared to one regular 7200 RPM harddisk.
Due to the fact the 7200 RPMs has a 10ms access time, 2x in RAID won't improve import speeds. It WILL improve overall system performance.
You can slightly improve speeds by turning off indexation and doing a proper defrag.
