Burning speeds.

[punjman]

Can someone explain to me the different "X" speeds when it comes to burners?

For example, 1x is what, 600 KB/s right? So a 10x should be 6000 KB/s right?

Reason I ask is because I have a 48x burner (and 40x media). When I try to burn a full 700mb CD with my old 16x burner, it takes about 5 minutes. I try with my 48x burner, and it takes nearly 15 minutes!

Same for the DVD part of the burner. I burned a 4.5gb DVD-r in about an hour or so with this same drive. Now I'm in the process of burning a 4.3gb DVD+R, and its nearly half way done... it's been 1 hour and 15 minutes!

my DVD burner is an 8x, but I only have 4x media... what is 4x on a DVD? Nero is telling me that it's currently burning at "4x (5540KB/s)". Is that correct?

someone please help me understand this.. Why is this supposed "faster" burner taking LONGER with CDs, and extremely long with DVDs? I know that a DVD takes about an hour at 4x, but shouldn't this thing be DONE by now? It's been nearly and hour and a half, and its only about 2/3 of the way done.<img src=smilies/cry.gif>

Need specs on your computer. Sure, I can burn at 4x on a crappy computer, but, most of the time is spent by burnsafe, because your computer can't stream data fast enough :P

Spex are:

1.7gHz Intel Pentium 4 CPU
512 DDR RAM
80gb Maxtor HDD 7200 RPM 8mb Cache


2 hours, 33 minutes, and only 93% done.


I figured the video card spex were irrelavant.

I know this info doesn't help you at all but on my p4 2.8, 512mb ram, 160gb HD, burning at 4x(dvd) it takes me about 35mins to rip and then burn a full dvd, using generally Nero to burn the iso that I make.

On CD-R(RW)'s 1x=150KB/s. So 10X is 1.5MB/s

40X is 6MB/s So 700/6 = 116 seconds. It should be about 2 minutes. However the speed of a cdr, like a cdrom is not constantly 40X. It may start as slow as 16X and as it gets closer to the edge it may get faster. Or something like that. Mine is a DVD-R 40X on the cdr side and takes about 4:30 for 700MB.

I try with my 48x burner, and it

Hmm....sell that burner. It's b0rked. or about to be....

At 4X it should be done in 15 minutes. Remember the X's are relative to time, no matter if it's dvd or cd (4X is 15 minutes, 8X about 8 minutes, etc)

Yup. DVD has more data per "spin" so to speak...so a DVD 4X > CDROM 4X

My Lite-on 4x takes 15 minutes to burn a dvd. Either it's bad or your computer can't keep up with sending it data at 5MB/s

Edit: Wait. When you say "burn 700MB cd", do you mean copying files from the computer to the CDR or from a disc to another on-the-fly? same with dvd?

CD-ROM speeds are not the same as DVD-ROM speeds. 1x DVD-ROM transfers at 1.35 megabytes (or 1,350,000 bytes) per second, compared to 1x CD-ROM speeds of 150 kilobytes per second (or 150,000 bytes). Just multiply that by your CD/DVD burner speed, and it should be right on the money.

This could be a software/hardware related issue.

It's hard to diagnose without knowing your CD/DVD burner. What brand name is it and what interface (IDE/SCSI) does it use? Also what OS are you running?

I mean copying directly from HDD to disc. I only have one optical drive in my system.

It is an IDE drive, running on Windows XP Pro (non SP2). The burner itself is an Emprex DVD+/- R/RW, 8x write, 4x re-write, 40x CD-r (my mistake it's not a 48x, just 40) and 24x RW.

I had about 10 gigs out of 80 left on my HDD, so i'm in the process of removing things I don't use, etc. I don't know if that would affect it, but you never know I guess.

edit: by the way, I have the latest version of their firmware on the drive. I upgraded it when I got it.
