Check you controller firmware version. Last time I checked, the current 
"stable" firmware release was 3.08.00.016.

dmesg | grep Firmware
twa0: INFO: (0x15: 0x1300): Controller details:: Model 9550SX-8LP, 8 
ports, Firmware FE9X 3.08.00.016, BIOS BE9X 3.08.00.004

Results from bonnie++ with default settings on my box (7.0-RELEASE, 
amd64, 480 MB system memory, BBU, write cache enabled, 7 drive raid-5, 
storsave = balance, NCQ on):
