Just going through their support email. 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.

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.
