Looked around here and have not seen any posts about this problem I'm having so here goes. I just bought my 3520 drive and installed it. Fastest speeds I can select in nero to burn DVD+ disks is 8x and CDRs is 32x. I did the speed tests and I am not seeing the speeds that they show in the tests. I am running Windows 2000 professional, the drive has 1.04 firmware. My friend bought this drive the same day I did and he is getting the same speeds. 8x DVD and 32x CDR out of a drive that should do 16x DVD and 48x CDR...... not good. Something is definately off here. Could it be a firmware thing.
