Master or Slave (ND-3540A)

Does the NEC ND-3540A prefer (function better) to be jumpered as a master or slave device? Or, does it not matter - either setting is fine?

The reason I ask is because some optical drives seem to perform better when set to master over slave; especially DVD burners. I am not familiar with the NEC ND-3540A (or NECs in general) so any assistance is greatly appreciated. Thanks :slight_smile:

my experience is that burners like to be set as master.
don’t know why tough.
