Great! Could you explain more specifics like connector pin layout, etc?

I believe that the base mechanism is the same but the control signals to
OD Drive(ODD) are different to make its performance better than SCSI
oriented installation. BTW, is there anyone verified this *wonderful*
experiment recently?
Could anyone tell me the *best* price of DS OD now?
