mfip was necessary, and allowed smartctl to work with '-d sat'
bonnie++ comparison. Run with no options immediately after system boot. In
both cases the same disks are used, two Seagate Barracuda 1TB 3G/S (twin
platter) and a Barracuda 500G 3G/s (single platter) in a zfs triple mirror
that the system was booted from. All are 7200 RPM drives with 32mb cache,
and mediocre performance compared to my hitachi 7k3000s or the 15k sas
cheetahs at work etc. Firmwares were the latest 2108it vs the latest imr_fw
that work on the 9240/9220/m1015/drake skinny. I wish I had some 6g ssds to
try!

A close race, with some wins for each. Latency on sequential input and
deleted files per second appear to be interesting salients.
A lot of the other stuff is back and forth and probably not statistically
significant (although not much of a sample set :) ).
I tried to control as many variables as possible, but obviously it's one
controller in one configuration, Your Mileage May Vary.
