I have both the 3500 and the 3520 drives. A friend wants one of them and doesn't care which one.
Now since he will be recording less and with less need for quality I want to keep the better drive.
I have read that many believe the 3500 writes better then the 3520.
However the 3500 has had far more time to get more mature firmware etc...
Over the long term which is the better choice?
A quick test comparing the 2 on my media TY02 showed that they are the same until the end of the disc where the 3520 starts to show signs of a weaker burn in nero speed. I don't have any Lite-On drives to do more Kprobe tests though.
Both drives have the latest Liggy firmware.
