You can get it here:

http://www.attotech.com/software/app1.html

Use the link for Windows SCSI utilities. When loaded, set the Length to 32MB, the Queue Depth to 10 and use Overlapped IO.

awsom thanks..I ran the test but get very slow performance...

26 write and 46 read raid0 w/2x 20 gig 7200 rpm western drives..My single drive does better ....grrrrrrrrrrrr

You wouldn't happen to have the card in a 33/32 slot on that board? The MPX chipset has some major latency issues on the 33/32 PCI bus. If you do move it to the 66/64 for better performance, though if it may otherwise throttle performance if it's not a 66/64 controller.

If not, then you may want to try a different stripe size. Since that can have a impact on performance. Since it's a data drive with probably larger files, try increasing the stripe. Fragmentation and available space can also affect the benchmarks.

It is onboard raid..It has few settings..Performance=raid0 and I set it to AV encoding maybe if I set it to desktop which ia another choice it will improve ,,,
