DRU800a firmware

Hey can anyone tell me if there is any difference in the firmware between the sony DRU800a and the LiteOn SOHW-1693S. I saw a mag article and they gave the lite-on a poor review talking about it’s firmware but gave the sony a good review saying it’s firmware is better than lite-on’s …i thought they would be the same considering they are the same drive?

@nutterx
they are the same
however sony alters(tweaks) the firmware slightly
