If your performance got much worse your stripe size is obviously to small.
bonnie is using single file transaction so don't expect to be much
faster than a single drive with this programm.
The ncr driver is running fine - the newer sym driver seems to be slightly
better but I asume that your controller is a plain 810 and not an 810A so
it is not supported by the sym driver.
