It is the maximum value I measure. It's also the value that I measure consistently with NCQ off, like with 2.6.18. Finally, even before I bought this PC, I did some research and the RAID with Raptors was recommended by someone with a lot of experience with them. He told me that I could count on (N - 1) * 75 MB/s (on average) for an array with N disks. I had expected 150 MB/s, which is about what I get. The 165 MB/s is on the outside of the disk (low partition).
