Differences in burn speeds between 32x and 48x burner?

[Salvador]

Does anyone know the actual difference in time it takes to burn a 800 mb disc full of data between a 48x and a 32x burner? How much time are we talking about here?

I burned a 500 meg disk at 32x, read and write to/from the same drive in 8 minutes. I burned a 600 meg disk at home at 40x (not sure the real speed using burnproof) in about 5 minutes, but using two different cd drives. IMO, I allways burn at 8-16x just to make sure I don't make a coaster, or that it can be read easier on other drives. The time you save isn't worth it for a few disks. If you burn a lot, maybe it's worth it, but I don't know anybody that does THAT many.

Edit: The 8 minutes broke out like this 3.6 to read, 3.4 to write, and a few seconds for the table of contents and other other overhead. The 5 minute broke out similarly.

It took you eight minutes? That's about how long it takes my 8x to burn a 700 meg disk .. about 9 minutes maybe.

It took me about 8-9 minutes on average to burn a 700 mb disc on a 8x drive. It took about 4-5 minutes for the same task to burn on a 24x drive.

I'm just wondering how long it would take on the faster drives out there now like the 32x, 40x and 48x.

Anyone know of a table for comparisons or an easy way to figure out burn times?

Thanks again.

A 32X burns in 3.5-4 min and a 48X just under 3 min. You don't get 32/48X on the whole CD since it's slower on the inner tracks so a 32X average speed is about 27X and a 48X's about 37X. Then you have to add lead-in/lead-out times aswell. The 48X is about 1 min faster.

1x=150KB/s

Given that, you should be able to guesstimate burning times...

32 x 150KB/s = 4800KB/s
48 x 150KB/s = 7200KB/s

After you do all the math it should take 32x 2.8 minutes and 48x 1.9 minutes to burn 800MB. The actual times will be a little more because of writing lead-in/lead-out(like Oreo said).

bah, all u guys are wrong.... difference btw. 32X and 48 X is minimal... a few seconds... because of the overhead.

Saw a review on extremetech that showed this clearly.

anything beyond 32X is a marketing ploy.

If you can tell the different between the 2 drives I would be suprised. I don't see a real need right now to spend any more money than it would take to get a 24x. Might save you a couple minutes but who cares? (of course if the price difference in minor I'd go gor the faster... just because)

Forget super high speed burners. You've got to find the right media and as one other poster has demonstrated, the damn CD-R might blow up in the drive if it's spun too fast.

Text Please read my edited copy above. Also, I basically agree with the last three posts in summary, the difference is minimal.

Again, please see updates above. There is a breakout.

my 24x took 4:30 mins to burn a 700mb cd. how is it taking ur 32x 8 mins for 500mb?

My 16x burns a 700 in ~7 or so minutes... i just bought one of those Yamahas but i haven't opened it yet... thinking i might return it since i don't think 4 minutes difference is worth $170. But then that t@2 thing makes me think twice...

 

[drewdogg808]

my old 12x did a full 700mb in about 7:30, my room mate's 24x did it in about 4:20-30. my dad's 32x did it in around 4 mins, and my current 40x does 700mb in 3:30. i would bet the 48x does around 3 mins.

Thanks guys.. It's just as I thought. The law of diminishing returns is kicking in big time beyond 24x with burners. I see a big difference in burn times between something like a 8x or 12x burner and a 24x, but not a whole h*ll of a lot of difference between a 24x and 48x burner. It's sort of like comparing a 1.6 ghz machine and a 2.0 ghz machine. There's not going to be a whole lotta difference in performance and it really doesn't justify the price difference.

I think I'll hold onto my 32x burner for a while yet until the prices on DVD burners comes down.

to his burner created an image from the cd to his HD and then burned it

i don't entirely agree...like the above mentioned, i saw reviews of 48x burners (TDK) achieving an average of ~37x for an entire 700MB disc.
no 32x is achieving that, so there is at LEAST a difference of 5x there...the 32x burners definitely don't average 32x for an entire disc, so we're talking more than 5x faster performance on the 48x vs. the 32x

all in all tho - the time difference is quite negligible...personally, i find my 12x still adequate, but then again, i'm not hard to please...
