Raid 0 Performance?

post #1 of 6
Thread Starter 
Hi, does this look right to you raid-savvy people? I don't like the look of the graph, it seems to spike downwards and tail off near the end... but then I don't know much about HDD performance!

All hard drives tail at the end.... the inner HD platter performs worse than the outer edge of the platter. The test begins at the outer edge of the HD platters and works itself inward with decreasing performance (as seen above.)
Once again...

Ok, thank you, that's cleared up the downward trend, how about the sudden downward spikes? What would they indicaate?
