I believe Scott did the original FreeBSD 1820a port but they where more than helpful in fixing the issue I had which was a quite nasty compat issue with seagate 400GB disks. > FYI, several people have claimed that the 1820a is "hardware" -- this > is untrue.

I believe you are wrong here and my own performance tests here backs this up, showing it keeps up with the more expensive areca in a number of areas notably, providing 180MB/s in sequential read tests from a 5 disk array.
