The manual, which can be found at http://us.lgservice.com/jsp/common/download.jsp?DOC_ID=KROWM000058431&FILE_NAME=KROWM000058431.pdf&ORIGINAL_NAME_b1_a1=GSA-4120B-ENG-55C.pdf&FILE_GUBUN=I (phew) says (page 10): Performance: Data transfer rate *Sustained CD-ROM : 6000 Kbytes/s (40X max) DVD-ROM : 22160 Kbytes/s (16X max) *Burst(ATAPI) 16.6 Mbytes/s (PIO Mode 4), (MULTI-DMA Mode 2) 33.3 Mbytes/s (Ultra-DMA Mode 2) So 33 MB/s is all you're going to get out of the drive interface. And this is enough for 16x DVD. Hope this helps, James. -- E-mail address: james | Space Opera: General term for a subgenre of adventure @westexe.demon.co.uk | SF in which the men are heroic, the women beautiful, | the monsters monstrous, and the spaceships make | whooshing sounds in hard vacuum. -- Eric Raymond
