New LSI 9200 series controllers: 6Gb/s, 2.88 GB/s seq. reads, 1.87 GB/s seq. writes

With the que of 1... Those tests you linked use much higher than 1.

So? The LSI card outperforms Adaptec in some of the random I/O, and by a very large margin even.
That just shows the latency is either wrong, or not important.
FYI, my 2xX25-E RAID0s on Areca have latency of 0.1ms in Everest.
But they sure as hell aren't slower than the X25-Ms in the graphs here

You forget the filesize

Which is related... how to random drive I/O???
