First 16x DVD+R Recording Tests Available 236

An anonymous reader submits "CD Freaks.com has made a first preview of 16x DVD recording. Many people wondered if 16x DVD recording would be too fast and data could not be delivered by the hard disk. The first tests show that this is not a real problem. 16x DVD recording means that a DVD disk is written in about 6 minutes . The test drive, a BenQ DW1600, also supports dual layer writing and writing at 16x to 8x media."

        Maybe they are talking about dual layer. which would make sense if not for the fact that it cannot write dual layer discs at 16x...only 2.4x infact.

        Either way...22mb/sec should be reachable by anyone with a hdd made wihtin the last few years. Most hdds can do over 40mb/sec sustainable (sequential read, which a dvd is), so only taking half that should not be a problem.

      Only ATA 133? I work at a computer store, and I get plenty of people with PII's and low spec PIII's coming in all the time who want to make DVD's. The salesman five years ago told them that the computer was very fast, so they typically accuse me of being just a damned liar when I tell them it may not work very well. Oh, and most home users have HP Pavillions and E-Machines and shit like that. You ever benchmark the drives in the super-cheap consumer systems? The drive diagnostic program we use at the shop can usually get ~5 MB/sec out of an E-machines. That's going to RAM, not another drive.

      A lot of people won't be able to use the 16 X features of this drive. OTOH, it probably has a larger buffer than a cheap 2.4x drive, so it will probably burn better at 1x than the old drives.

      The difference, though I am not an expert by any means, between 8x and 16x dvd+r (or 32x and 48x cdrs) is the guaranteed labeled quality. You are guaranteed by the company who makes the medium that it is capable of being burned and read at said speed.

      That doesn't mean it can't be written at higher than said guaranteed rate; on the contrary, I have cdrs that are guaranteed to write/read up to 48x, but I write all of them at 52x.

      No, and CDs don't work like that either. The situation you describe was an isolated incident. Even a 1x DVD reader (e.g., a DVD player) can read a 16x-burned CD. In fact, there should be no physical difference between a DVD burned at 1x and one burned at 16x.

        Sorry to burst your bubble, but they most certainly do.

        It most certainly could be that an old drive can't read discs burned by newer, faster drives. The older drives may be less fault tolerant. Pre-pressed discs could be ok but a disc burned too fast could have pits just slightly too close together or too far apart that confuse the older drive.

        I have seen this happen with CDs on more than one occasion. Slowing down the burn speed made a disc usable by the older drive. Think PSX backups.

        In fact, there should be no..

          IIRC, the reason your old CD drive might not read a CD-R burned at high speed is because the new high speed writers use CAV (constant angular velocity - i.e. the disk RPM remains the same regardless of whether you're writing a track near the hub or near the edge). Older CD drives may not be able to do CAV since the CD standard is for CLV (constant linear velocity - the bit of disk right over the head is always going the same speed relative to the read head, hence the disk is spun faster on tracks near the hub and spun slower on tracks near the edge).

      The physical limits of CD burning (the speeds that often cause shattering) aren't because CDs are easily breakable. It's because CDs are imperfectly manufactured, and therefore imbalanced - a CD spinning at 52x that isn't perfectly round will be wobbling with an incredible amount of force.

      So... for DVDs to be able to spin at faster speeds, the discs (and drives) will have to be manufactured to very high specs. Very slight variations in the roundness of the disc would cause enough vibration to break the disc. A non-round or off-center hole in the middle would also cause this problem.

      • I recall reading that a major contributor to optical media fatigue is crystalization of the plastic. The faster the disk spins, the more intense the laser beam must be, so the dye can be converted in a shorter time. This more intense laser beam also heats the plastic, which causes some structural change in the plastic. When the plastic cools, some of it crystalizes. Crystaline plastic is fragile. At the high stress of modern drive speeds (a CD spinning at 48x is spinning at 200 miles per hour on its outer e
      • Perhaps this [powerlabs.org] will change your mind on the strength of polycarbonate.

    1. Unless you have a smoking hard drive you're not gonna see 16X speeds (ATA hard drive? you wish)

    2. Unless your PC is relatively fast as well, in addition to a good deal of RAM (as in their test system) it's also not going to happen.

    3. And an IMPORTANT note: Don't get caught up in the craze of getting the newest thing, this will probably cost an unholy amount when it comes out, and the requirements will be really high, which will add to the price as well. I have a 4X DVDRW and although it isn't anywhere near as fast, I don't need godly system specs to use it. And neither do I need to drop anything else I'm doing. Also note that on a lesser system that they tested it with you will see significantly slower writing.

    The average write speed on this drive barely qualifies it as a 12x drive. Claiming this is a 16x drive is silly.

    8x drives typically pull in average write speeds of 0.4 to 0.6 x lower than their rated spec (Like the 7.44x quoted in this article)... but THIS drive is pulling 4.7x lower than it's rated spec. It's burning at 11.32x... In my mind, that classifies this drive as a 12x, NOT a 16x.
    • Well, I don't think any 52x CD writer can write a 52 minute CD in one minute.

      In short, the drive manufacturers lie. When the drive speeds go up, RPMs go up, but they have to limit them otherwise imbalanced discs will shatter. RPMs being a limiter, they are effectively CAV drives, so the data can only be written so quickly near the center. Usually the stated write speed is only on the edge of the disc.
  • they have already reched this, and can basically burn at instantaneous speeds

  • Where is SCSI devices nowadays. That was the greatest internal/external interface you can get. How it's just obsolete. There is a whole 2 brands of SCSI DVDs, all of which remain at $100+ since there is just no competition. Has anyone tried the SCSI-to-IDE converters?

    • Using a SCSI-IDE solution would make you lose out on the speed increases, if they existed. Check out some reviews of those Raptor SATA drives that run at 10k RPM, they've got almost identical speeds as SCSI.
    • What? You mean they've replaced MFM and RLL drives already?

      Hell, I hope my ESDI drive isn't rendered obsolete any time soon.

      Now where's that 128KB 8" hard-sectored floppy disk I use for backups?

    You know what, screw these fast speeds. I hate it. I burn my DVDs at 1x because the Sony Playstation and other stand alone dvd players barf on discs that are even burned at 2.4x or higher. 16x is just plain stupid, really stupid. What in the hell would use that for? You couldn't play it in an Xbox, PS2, or 90% of stand alone dvd players. Yeah yeah, I know - the disc type matters - but even the best discs barely read in my PS2 burned at 2.4x. Barely is being generous. What I REALLY want is the ability

    21MB/s isnt all that fast. The new WD SATA drives are from 35MB/s to 60MB/s. No, a 5400 drive wont cut it, but any 7200 drive made in the past 2 years should be good. See here [storagereview.com] and look at "WB99 Disk/Read Transfer Rate - End in MB/Sec".

    I am perplexed by the numbers given for this so-called, "16x" DVD burner. Let's start with the rated speeds, and compare it to my 2-month old Maddog 8x Dominator 6-in-1 Dual DVD burner.

    First, the BenQ:

    Writing DVD+R discs: 16x
    Writing DVD+RW discs: 4x
    Writing DVD+R Dual Layer discs: 2.4x
    Writing CD-R discs: 40x
    Writing CD-RW discs: 24x
    Reading DVD-Discs: 16x
    Reading CD-Discs: 40x
    Access time CD/DVD: 120ms
    Buffer: 2Mb

    Now, my Maddog:

    Writing DVD+/-R discs: 8x
    Writing DVD+/-RW discs: 4x
    Writing DVD+R Dual Layer discs: Unk*
    Writing CD-R discs: 32x
    Writing CD-RW discs: 16x
    Reading DVD-Discs: 12x
    Reading CD-Discs: 40x
    Access time CD/DVD: 110/130 ms
    Buffer: 2Mb

    As you can see, the specs show that my 8x Maddog is almost as fast as the 16x BenQ!

    Then, there is the statement in the review that says it only takes an average of about 6 minutes to burn a DVD at 16x (actually, average speed is only 11.32x). Compare this to the 8-to-9 minutes it takes to burn a DVD at 8x.

    These results are underwhelming. I would expect more from a 16x DVD burner.

    *Rumor on Usenet is that some DVD burners, such as the Pioneer A07 currently on the market, will be able to burn dual-layer DVDs with a simple firmware upgrade. Indeed, some of these models already *have* burned dual-layer in hacked versions. No word on where people got the dual-layer media.
