I just purchased and installed a LiteOn LH-20A1H drive. I also have a BENQ DW1640. I have been doing some burns with ImgBurn on Ridata single layer DVD+R media and am getting significantly slower write speeds on the LH-20A1H (6X) as compared to the BENQ (12X). The media is rated at 16X. The disc information screen in ImgBurn reports the following:
LiteOn: Supported Write Speeds: 2.4x, 4x, 6x
Benq: Supported Write Speeds: 2.4x, 4x, 8x, 12x, 16x
I would appreciate any info as to why the write speed on the LiteOn is so much slower.
