What's the diff between LDW and SOWH series?



In particular, the LDW-851S and SOHW-812S seems to have the same specs, dual 8x DVD burner, what’s the difference betwen the two model/series?


the sohx stuff is hardware developed in partnership between lite on and sony (I’m told its sony hardware in there).
the 851 is 8x +R, 4x -r.
the 812 is 8x +R, 8x -r


All the same… LiteOn just decided to slap on Sony’s name as a sign of their partnership, which they’ve also done for their latest CD burners and combos.

812S has newer hardware and can do 8x -R…
