Hi
I have a couple of harddrives (same model) that I have put in a striping array. In Nero you can go to File->Preferences->Cache, about the middle of the dialogue there is a way to test drive speed. When I look at the drive speeds like this in Nero the striped array shows at same speed as 1 of the harddrives by itself before being in the array.

I thought that due to striping the speed would almost double?? Is it something about the way Nero performs the test or do you think the raid array is not functioning properly? Is there some benchmarking software for harddrives that will give more accurate and detailed results?

Thanks,
Dance
