16X DVD-ROM READS 30% slower than 8X BURNING

Discussion in 'Amateur Video Production' started by Monkey Monkey, Apr 19, 2004.

  1. I use a 16X DVD-ROM and DVDshrink to read DVD disks
    and copy them into my system hard drive. The box that
    the 16X DVD-ROM drive came in claims a maximum transfer
    rate of 7200 KB per second. Shrink displays a verification
    of the 7200 KB DVD reading transfer rate when ripping.

    However, when I burn the disks using my 8X Liteon burner,
    Nero reports a maximum transfer rate of roughly 11,000 KB
    per second.

    Why is a 16X DVD-ROM reader's max transfer rate 30% SLOWER than
    the max transfer rate burned on to a DVD+R disk at 8X???

    Reading or ripping? A DVD-ROM will READ at the higher speed, but it
    can't RIP, because the software and CPU are processing the rip.
    Transfer rate and
    ripping speed are two different specifications.

    I agree with your point about "Transfer Rate" and "Ripping Speed"
    being two different things, due to the re-encoding involved in
    ripping. However, I think you're losing sight of the big picture.
    The technical documentation on the cardboard box that the DVD-ROM
    was sold in states "16X DVD-ROM, max transfer rate 7200 KB per sec".
    It's widely known that a DVD+R burned at 8X writes data to the disk
    at approximately 10,800 KB per sec. So again I'll ask:

    The real answer here is a question: Who wrote the advertising copy on the box?
    A knowledgeable design/test/production engineer? Or a copy writer?

    Any other questions? Or do you buy your toothpaste on the basis of the number
    of babes you expect it to draw? Maybe you return address answers this

    Make sure you have the 80 wire ATA cable and not the flimsy 40 wire as that
    could be causing your problem.

    There is no mystery, you merely haven't actually read the
    specs for your drive. DVD drives often read different
    media at different speeds. Typically, a DVD-ROM drive
    can read single layer pressed discs the fastest, dual layer
    pressed discs slower, recordable and rewriteable discs
    even slower. The box your drive came in probably lists the
    fastest it can read single layer pressed discs in big print,
    and relegates other performance characteristics to small
    print elsewhere.

    I don't think the wire will change the stats on the drive that are in print
    on the web, manuals and side of the box
