DVD-Rs go 8x 237

      1. price: the cost per GB of DVD-R crossed hard disk prices recently, though they are still very close.
      2. durability: DVD is not as susceptible to physical shock and magnetic fields as a hard drive.
      3. movability: more PCs can read a DVD-R than have a slot for inserting a removable IDE drive.
      4. size: when what you want to store fits fine in 4.7GB, a DVD is a much nicer form factor than an IDE hard drive (so far). (e.g., daily incremental backups extending back for a full month.)
      5. movies: I can't create a movie on a hard drive and then stick it in my consumer DVD player (so far).
      However, DVD+RW and DVD-RW would certainly be more attractive for general data use if the operating system actually supported them as random access devices. Don't know about *nix, but Windows does not support such access until the next version (XP supports drag and drop, but simply copies files to a temp area, and then waits for you to tell it to do the One Big Burn).

      On the other hand, -R seems to be the media format of choice for people in the content industry, and -Rs backers are no slouches, either (Panasonic, Toshiba, Pioneer, and sometimes Sony, whose set-top DVD recorder supports -R/RW and +RW but not +R).

    Personally I want more space on a DVD. I'm quite happy to wait twice as long if I can store more. In terms of a backup solution

    Your typical HD costs 200 pounds for 250GB.
    Removeable caddy for HD costs 10 pounds
    One-off caddy container for PC is 15 pounds.

    A DVD-/+/RW/RAM drive costs 105 pounds.
    A DVD-RW holds 4.5GB and costs 17 pounds for 5 (=22.5 GB)
    Total cost of 250 GB DVD media is (105+187 =) 292 pounds.

    So, the DVD just about scrapes home as cheaper during the third 250 GB. You may be able to get something off if you buy your DVD's in larger bulk - those prices were all I could see offered, and they're the cheap end as well. The "branded" names make the argument even stronger since "Sony" DVD-RW's are 22 pounds, not 17...

    On the other hand, you now have 165 DVD's with your data on somewhere. At that rate, it's surely better to have 3 HD's and a caddy slot on your PC ? In an emergency, you can even get by for a day or so using the data live off the disk.

    If, however, you want to pirate DVD's and play them in your home cinema, then sure, that extra 7 minutes you'd have to wait over a 4x drive would seem an eternity...

    • I'd find a better dealer if I were you... Hint: Don't shop at PC World.

      250GB is cheaper at 2*120GB which will set you back 114+VAT.

      Branded DVD-RW is *much* cheaper then you suppose - retail price for is 8 (inc vat) for 5 branded traxdata.. unbranded stuff you can get for 5 for 5. If you don't need RW (why should you? it's for backup) then you can half those figures.

      A dual format +/-RW drive will set you back ~80 inc. vat.
      • All the prices save the media were from DABS online. The media was the best prices single-page ad I saw in the back of computer shopper.

        I did *say* you could get them cheaper...

        I was using RW rather than R to level the playing field. The HD can rewrite, and some people rotate their backups in cycles...

    • Somebody is going to have to do a rethink when SATA replaces PATA. The removable carriers for SATA use the SATA disk's data and power connectors rather than a specially designed and built connector for the task. The plug/unplug duty cycle for SATA disks is rather low, similar to what scsi SCA connectors are, not the 10's of thousands that a PATA carrier was rated for.
      • Typically it's the caddy that takes the brunt of any plugging/unplugging - the caddy receptacle mounts in the PC case, and the caddy plugs into that. The disk plugs into the caddy.

        At least, in all the ones I used to use at the MoD.

    I've always had the impression that gradually incrementing the speed of CD/DVD writers (and other products) is just a matter of marketing and not of actually beeing posssible to offer the technology.
    When CD Writers started going up from 8x, 12x, 16x, 24x, 32x, 40x, 52x.... it seemed ridicolous! I simply thought the 52x technology was already available when the 8x was out in the stores.
    I know that increasing the writing speed is probably not just making the CD spin faster.. but then, what else is it?
    It looks like as if with the DVD, everything is repeating. Can someone give me a reason why DVD writers are not faster already apart from marketing reasons and companies just wanting us to buy all different speeds? Is it actually impossible to have faster DVD writers at market price right now? or is it a technical impossibility?

    Unfortunatly this format hasn't caught on and the latest LG 4040B drive doesn't support dvd-ram with the protective cartridge. It does do dvd-r +r -rw +rw cd-r and cd-rw. Maximum PC mag states it can write a 4g dvd-ram at 3x in 20 minutes and every bit of your binary file *will* be there.

      All media, including +R, -R and -RAM, need to be stored and treated properly.

    I bought a 4X when they dropped to $125, and am pretty happy with it. I won't spring for a faster drive until I can get a DVD-9.

    But to my real question: How fast will they go? Most seem to be married to the 33MHz IDE spec on which all removable media are based. IIRC that's one byte (8bit parallel) at 33MHz...or about 25X (118GB/hr) with the bus completely saturated. So, without moving to IDE100 or IDE133, 20-22X seems to be a limiting factor.

    Someone above mentioned that 16X DVD speed has the same rotational velocity as a CD at 48X. Now, since 52X seems to be the CD-R limit based on the likelyhood of media disintegration that would seem to limit the DVDs to about 17X.

    I suppose there is the proposition that a two laser DVD-9 could overcome the rotational velocity bottleneck by writing to both layers at once, given that the file layout cooperates. And if writing a DVD-18 becomes a possibility (unlikely), then a four laser system could write all four layers at once. But this requires moving the CD/DVD devices beyond the UltraDMA mode 4 they seem limited to.

    So...where will the DVD speed end?

    • I was just having similar thoughts, based on "8x DVD write is about the same as 48x CDR write": what speed is that DVD RPM'ing at?? at what point will the DVD disks start to shrapnel, as has been demonstrated with CD disks starting at around 56x?

    • Base speeds:
      1x CD speed = 150 KB/sec.
      1x DVD speed = 1350 KB/sec.

      Current speeds:
      52x CD speed = 7800 KB/sec.
      8x DVD speed = 10800 KB/sec.

      If 8x DVD thruput is possible at the speed above then you might think that thruput would be possible with CDRs as well. After all, 10800/150 = 72. Why aren't there 72x CD-Rs? DVDs use a finer focused laser, packing the information tighter on the disc and requiring lower rpms. For a CD-R to be written at a comparable speed (thruput) it must run at a faster speed (rpm).

    I've got one of the plextor PX-708a's and have been using it for about a month and a half now. I've been very impressed with this unit for a couple of reasons.

    When I purchased it, it was the same price as 4x dvd burner/combo burner drives at the time.
    Covered all formats (like a good combo drive should. DVD_+R/RW, CD-R/RW).
    Still had a high burn speed for cd's (40x), quite a few of the high speed combo burners I was looking at would only cut a cd at around 24x.
    It's offered with a white or black faceplate (I picked black to match the new pc I had just built) :P

    This is the first plextor drive i've owned, usually staying in the yamaha camp. It came with 1-8x DVD+R and my attempts to purchase more at fry's/staples/compusa all failed miserably. Once that one was gone, I started trying to burn 4x rated dvd+r's at 8x and have gone through a couple of 10 packs with no problems. I use this unit in a winxp machine, with Nero Ultra to burn it (I didin't even look at the software that came with it, I think it was a plextor branded app) and have been very happy with it overall.

    I started reading this thread and started seeing the usual "But why, 8x is too fast" bla bla bla type stuff, but until we get to the generation 4+ of these devices speed is still going to be the selling point of dvd burners. Remember when the 4x cd burners came out? People were saying they're a waste of money and you don't need something that fast then too. But now, we're at the point where you can pretty much just go and buy a new cd burner without checking the speed and you've still got something screaming fast and rock solid. So stop bitching about device enhancements.
