Picking the Right Drive

When we first started looking at DVD recorders, there were only two reference designs out there, and they supported different DVD formats. Ricoh took a backseat for about a year and competition from NEC, Sanyo, Hitachi, Philips and MediaTek began to heat up while virtually removing the format barrier (read up more about Ricoh on the NuTech page). The single layer format wars are largely over without incident - with some exceptions. Those who bought Ricoh-based drives and were promised additional media support and faster firmware upgrades still hold memories of getting burned (pun intended). What about all those countless drives that would perform exceptionally on only one brand of media? It isn't just one set of recording manufacturers who have poor track records; they all have dark spots on a relatively short industry life. Our objective is to decide which one of these drives in our analysis performs the best for the price, so that no one gets burned.

How can we determine what the best performance of a recorder is? Although we largely compare one unit to another, the process is entirely quantitative - there is a systematic method to determining the best drive. Price, write quality, write speed, read quality, read speed, media support and feature support gauge the performance of our burners. Here is a checklist on how to pick the right burner.

Price: Perhaps one of the strongest weighted elements to evaluate, we want to know if the price makes sense. Two years ago, paying several hundred dollars for a DVD burner made sense. Paying over $100 today for a burner seems a little silly, even if performance is really outstanding. We have enough competition from several competing designs and dozens of manufacturers.

Write Speed: All of our burners burn at 16X, or do they? Looking at the average write speed of a burn is important to us, but mostly, it is just to let us know if a burner is doing something that it shouldn't. A 5-second difference between two burn speeds does not constitute a design win, but one drive writing twice as fast to another drive does.

Write Quality: The most important quantitative analysis that we do today is the write quality. As we mentioned before, no drive today will burn a DVDR significantly faster than another (with some exceptions), although perhaps the ones that do are doing it wrong. A burner that burns a disc with no errors (rather than a burner that burns a disc 5 seconds faster yet unreadable) constitutes a design win.

Read Speed, Read Quality: Probably the least weighted element in a DVD purchase. Obviously, a DVD recorder that can't read discs, or reads them improperly is a problem, but that flaw occurs extremely infrequently. Seek times and read quality both fall in this category.

Media Support: Choosing the right burner and choosing the right media are hand in hand with each other. The DVDR audience has been well trained to recognize the differences in media due to "the format wars", and those buying their second and third DVD burners tend to buy a burner for a type of media that they use. Now that the market is a little more mature, we are starting to see differences in each individual media brand. Ritek, Mitsubishi, Yuden, and CMC all have significant differences between each other, and some tend to burn faster and cleaner than others. Most of our examinations are limited to Ritek and Mitsubishi media, only because of the volume of testing needed to be done. The DVDR industry has shifted into the hands of the media manufacturers; even though a drive may promise a write speed for a particular format, if the drive's firmware team isn't working with all of the media outlets, then said drive will never perform correctly.

Another trend that we notice in media support can be generalized in maturity. Retail drive manufacturers who OEM the drive out to other manufacturers have the best media support. By OEM (original equipment manufacturer), we mean the manufacturer who produces the drive for a brand, but also sells under their own name. Most optical storage devices have a single programmer working on firmware for their drives; they only modify the OEM firmware by changing the name inside the drive BIOS - and sometimes not even that! The firmware teams are adding new media support and write descriptors. Write descriptors are the basic, low level operations that tell the burner exactly what to do, to write at a certain speed to a certain media. Generic write descriptors exist for all media, but performance comes from finely crafted write descriptors for a media speed and brand. Thus, manufacturing teams with large or talented firmware teams tend to perform better than ones who do not have such teams.

Determining if a drive can provide the best media support is extremely difficult to ascertain, but knowing that a drive supports the major write descriptors correctly is the best step in the correct direction.

Other Features: Booktype capabilities, Mount Rainier and error feedback are also important options to consider when choosing a drive. Most of these features have declined significantly in importance over the last few years, but some people place their entire purchase decision on booktype options. If you've never heard of booktypes before, you probably don't fall into that category. Setting a booktype (bitsetting) is just the process of telling your burner to convert a DVD+R disc "virtually" into a DVD-ROM instead. This feature is important for some people who have older set-top DVD players that cannot recognize the "bit" that determines what type of DVD media is sitting in the drive. You can check out how this works in more detail in an older article of ours.

As we already briefly mentioned, the format wars are in passing. Although the debate between +R and - R format seems to rage in various enthusiast circles, +R seems to be winning in terms of market penetration and speed. The DVD-R consortium does not have a dual layer, nor 16X media available yet, and they have been playing catch up for almost two years now.

    Just want to add an info about BenQ DW1620 pricing. I bought DW1600 3 days ago at SG$ 98 (that's about US$54-58). After upgrading the BIOS, it's now on DW1620's firmware B7M9. If the physical is the same as DW1620, it's effectively the cheapest 16x among the rest. Reply

    On page 13 where you published the test results with Ritek G05 media the graph heading indicates DVD-R 8X write speeds, however the smaller print below that indicates DVD+R media. Can you perhaps clarify if this table is based on + or -

    Thanks,

    Thanks for the great review! Just one note of possible mistake - you have the DL R speed of the ND 3500a @ 2.4 when I believe it should be 4x. Reply

    Maverick215: Testing 8 DVD drives takes more than just a few days. Our roundup was submitted Mid October and posted Nov 1.

    The zip files are at the bottom of each drive page. Look at the bottom of page 6 for the Benq.

    KristopherKubicki: Let me see if I got this.
    You say that you tested the most recent firmware available on the Benq. Your previous review was posted September 29th, 2004. The next firmware released was B7K9, files in that zip are dated 9.27.04 and it was posted to benq's US site 9.29.04 (the same day the initial review was released) So if you "... tested with the newest firmware possible" then either http://images.anandtech.com/reviews/storage/16xosd...
    is outdated or you tested the drive for 'this' roundup 'before' the previous review was released. I'm inclined to think the latter is true based on the features of B7K9. Similarly, "(your) second look at the DW1620 uses the same firmware, although (you) were able to get some better media." I assume you got this media prior to 9.29.04 as well...

    Just trying to figure this out for myself here (btw I can't seem to find the .zip files you refer to). I have no vested interest in any of this, just like to see things clearly.
    ---
    Back to the firmware issue. B7K9 introduced a great many write strategies changes.
    I will pick out the media tested that seems to have changed since before B7K9
    Mitsubishi (MCC 03 RG20) DVD-R is now 16x (should put speed about the same as NEC)
    Mitsubishi (MCC 003) DVD+R is now 12x (should be about the same as the RITEK test on the BENQ)
    Ritek (RITEK R04) DVD+R is a 16x supported media
    Mitsubishi (MCC 004) possibly had a write strategy change (uncertain) to make it full 16x; same for (RITEK R03)

    Don't get me wrong I understand you guys can't test the latested of the latest ultra alpha zeta laser tool chain master firmware (yes I made that up as I went) and compile a review/comparison instantly. But I would expect if you are using new material for a new review that you use the latest firmware/software etc that is available at the start of that review/comparison. At the VERY least you could mention that firmware revisions/updates/etc have been made (google is easy to use) and likely improve the results of XYZ. Further mentioning new features have been introduced, such as in B7M9 (released 10.27.04) where high speed (8x) disc quality testing with nero cd/dvd speed has been added (must use latest firmware, with latest software).
    I may not expect to see such things on (insert company fanboy website here) but I certainly expect nothing less than what I suggest from "the leading IT source for hardware analysis and industry news"

    BTW CDfreaks says the 1.01 firmware is out. Reply

    Actually if you look at store pickup it shows in stock (for me) at several places. But no one at those friggin stores ever answers the phone.

    Going out there right now to see, pick up 3 if they have them.

    Thanks for heads up.

    The Modesto, Calif Best Buy had 5-6 the night I got mine. I was shocked to see it there. I am glad I bought it. My friend has the 712 and never a coaster after at least 500-600 DVD's and hunderds of CDR's. And the DVD's play on anything in my house including a Sony DVD that hates all burned media.

    Same with the 716a so far.

    We will test a PX-716A as soon as we get a sample.

    Nm they are backordered till the 11th - 17th. I'll have to check my local BB's to see if any of them got it in. Reply
