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

[Guest]

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:

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

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
question:

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
