DVD+RW drives write cd-r/w slow?

[Squ]

i am looking into buying a dvd+rw drive for my computer, to replace my current cd-rw. i have been looking at a few and i notice that the fastest cd-r/rw speed that a DVD+RW drive writes is: 16X / 10X (or so)..

my question is, why are they so slow at writing CD-R? i have a 24X10X40 CD-RW drive now, and i dont want to spend all this money and have it write slower.

I heard that DVD+RW's numbering system works differently, for example 1X in DVD+RW is not the same as 1X in CD-RW (is this true) if so how can i go about converting the speed?

Thank you for your time!

You can't.

The write speed for DVD? is 9 times as fast as forCD-R. I.e, 1X DVD is 9X CD.
But the CD burning rate, because of the second, CD laser, is the CD X.
They are dual lasers, one burns DVD, the other burns CDs.

I'd advise you to spend 39 bucks to get a 48-52 X CD burner. You don't want to wear out a 150-300 buck DVD burner on CDs anyhow.

Cheers,

I don't know why DVD writers write CDs so slow, my guess is the manufacturer is trying to sell the best DVD writer for the cheapest price, and anything which increases the price gets left out.

DVD writers are pretty abysmal at both reading and writing CDs. If you are going to be burning many CDs then keep the CD burner.

And it takes about 1 hour to burn a full DVD at 1x. That is about 1350 KB/s. Even the DVD+R/W format as the same speed rating, however, I don't think 1x exists in the DVD+R/W format - the slowest speed is 2.4x (about 25min for a full DVD+R/W).

ALL burners,CD and DVD started at 1X. I mean, you have to have a standard, right?.
1X media will be around till they either get their investment back, or they sell the last disk, or a combination of both. When they quit selling, they'll quit making them, I hope, although it is possibe they run a couple million that don't meet spec, won't burn at the rate they shot at, so they mark them down to a lower speed rating.

Kinda like the disks ( CD ) I have bought, marked 40X, burn at 24, period, and the unmarked, totally generics I have bought that WILL burn at 48, no prob.

Then again, some burners are better than others, and burning software, also.

I consider Nero good. Some others don't like it.

What you gonna do?

I think you will find the CD recording speed on a DVD recorder has a lot to do with the size and weight of the optical block in the recorder itself.

They are quite a lump in DVD recorders - don't forget the track pitch on a DVD is a lot narrower than on a CD, so trying to record a CD-R means the recorder is trying to emulate a CD recorder, and that means double stepping the sled when trying to follow the pre-groove. Don't forget there is a wobble on the pre-groove that gives the recorder its position and timing reference, and the recorder needs to follow that.

When you consider how much work a recorder has to do during a burn, it amazes me the damn things can record onto CD-R's as well as DVD-/+R's in the first place.

Squ,

The Lite-On LDW-401s is a DVD+R/RW burner. It burns DVD+R at 4x, DVD+RW at 4x, CD-R at 40x, CD-RW at 24x and reads DVDs at 12x (not knobbled for ripping either). There is possibly firmware updates to burn to -R/RW also.

Good value and a drive that can reduce the need for a DVD-Rom and CD-Writer, depends on your usage I guess.

What's wrong with burning at CD-R 16x, which takes all of 5 minutes? Even the fastest 52x burners seems to take 3 minutes or so to write. The extra two minutes aren't the end of the world, especially since I wait 16 minutes for any DVD-R burn.

This reminds me of an old driving video I saw many, many years ago. The guy that insists on going 10 miles over the limit, yet only saves 30 seconds as compared to the guy that stayed at the speed limit the whole time.

Is it really worth it? If so, go for it. But not to most of us, so that's probably why the CD-R burning speed is so "slow".

Lordsmurf,

How very, very true. Jeez, no one seems to remember 1X CD burns, and how goddamned happy we were to be able to store an ENTIRE HDD on one CD.

Of course this is in the era of BIG 540 meg HDDs.

Actually, most of our present clientel seems to be made up of younger people who have never known small drives. I still have them in stock from 120 megs up. Before that, I was using tape cassette recorders. And they did not record that much on a "data" quality, 30 minute cassette.

But, man, did they sound cool when you accidentally put one into a tape audio player. Kinda like Hindu music.

Back in the days when people borrowed CD's to piss off RIAA, and download was not a word many people knew. At 28.8 or slower, it was not an activity many people did anyway.

Funny! Never heard that one before. Must've been before my time.

But I do have an old box of punch-cards I got from my father when I was a kid. I keep it for the historical value. And yeah, my first HD was 400MB, 800 after MS-DOS 6.0's DoubleSpace, all on a fast 486DX. I was the cool guy because I had a scanner and Internet access! Burning a CD-R at 1x sapped up all system resources, locking you out of your computer for about 75 minutes, the discs were about $2 each, and because the burners were so expensive, I used the one my friend bought after saving up for it for several months.

The CD player in my car cares.

My CD Walkman cares.

Any player I use where the disc is likely to get wrecked by heat, scratches, being sat on etc, cares...
