Of course I get it. If the chip did not have the guts to perform the RAID calculations fast enough, I doubt that both Intel and HP would have chosen this chip for their RAID controllers. I think the problem is somewhere else (i.e. the raid chip is fast enough). I suspect the problem is caused by not enough cache ram, the lack of the battery (possibly disabling write cache even though I tried to enable it in the settings), or some obscure issue with the particular SATA drives I am using. These are not HP drives, as they do not sell anything this large (500GB drive). Maybe this is why...

In case I'm being too subtle: I've written four messages in this thread about how the important thing is XOR performance of the RAID card. The above is yet another message in a series of messages which *DOES NOT ADDRESS THAT QUESTION AT ALL*. We really don't care what it is, or who uses it, or what color it is, or any other damn thing except how fast it can perform the XOR calculations needed for RAID 5.
