VSO latest results April 17th 2005


1. General Information

The latest builds of CopyToDVD and BlindWrite include an optional feature where a statistics database is updated every time a burning sequence finishes and information about the used drive, media ID, speed, error code, if any, etc is automatically posted to the VSO database. VSO Software, a leading CD/DVD software developer, kindly offered their latest statistics to CDRInfo.com.

VSO comments on the new feature saying "... it will be an opportunity to be more reactive and provide more reliable products. By detecting new drives released on the market, latest firmware releases, and statistics about media usage and failure rate, the real time information will be used to improve the technical support and knowledge. We don't collect any information about users or the kind of data burnt. Of course, this is optional, and users can deactivate the feature during installation. Drive and media manufacturers will be able to benefit from the data collected to improve their own products as well. They can contact us for more information. Users will benefit from this exciting database by checking which drive and media are the most reliable...."

- Why should I use VSO's anonymous database feature?

You can use VSO's anonymous database feature for various reasons:

  1. In order to improve the quality of VSO software and to establish a chart of good media, based on real world experience on a wide range
  2. If you refuse to participate, no information is sent
  3. If you accept to participate, a small block of information is posted at the completion of each burning sequence
  4. The information sent is very small and there is no noticeable impact on system performance

- What kind of information is collected?

Each time a burning sequence finishes, the following information is automatically posted to the VSO web site :

* The VSO software that has submitted this information, and it's version number (ex: "C3 3.0.48.94" for CopyToDVD)
* The burning device manufacturer and model string (ex: "PIONEER DVD-RW DVR-108")
* The firmware revision of the burning device (ex: "1.18")
* The inserted media identification string (ex: "RICOHJPN-W01-01", a ricoh DVD+RW media)
* A unique identifier for the media (a hash string, which differ for each series of media. this help to find out if media is fake of good quality brand)
* Media Kind (a numeric code representing the type of media DVD-R, DVD+R, ...)
* Logical Write Speed (The information returned by the drive)
* Burn Size (size in sectors of the data to be burned)
* Written Size (size in sectors of the data effectively burned)
* Burn Date (When it's been burned)
* Completion Time (Time to burn, from start of lead-in to start of lead- out, with Written Size will give us the real writing speed)
* Status (a code indicating everything went ok, or in case of error, what kind of error ocurred)

All the information sent is protected with a hash key, to avoid malicious attempts to send fake information. As VSO claims "...We *do not* collect any information that may help in identifying a given computer or person..."

- How can I turn this option off?

You have to create a registry key, by following these instructions:

If this value is absent or set to 0, no information will be sent. Otherwise, the aforementioned information will be uploaded to the VSO statistics database.


2. Most popular drive manufacturer

We have the data collected from VSO's database where the current results refer to the period between the 11th ~ 17th April 2005.

Before proceeding please read the following statement:

"...The following stats are based on real burn reports using CopyToDVD and BlindWrite. Because of the privacy protection, the data is not grouped and analyzed per user, so please understand that a small number of bad drives or computer configuration can influence the results.

RATIO value is a complex calculation between the number of reports and the number of burns successfully completed. Nevertheless, a media burnt successfully doesn't mean the result can be played correctly in a dvd home player, or by computer devices, so understand this data needs to be understood by expert people. Ratio = 1.0 means perfect result (on a write completion point of view)..."

- Most Popular Manufacturer

LG continues to be the most popular manufacturer at 23.75%, with NEC following next at 17.96%. LiteON is the third most prefered manufacturer with 13.85% and Pioneer comes fourth with 10.84%.

Let's see which brand is considered as the most reliable. Plextor takes first place with a ratio value of 92 ratio (success/uses), with NEC and LiteON following also at 92. Notice here that the reported ratio illustrates that the burner can successfully complete the burning process, which is irrelevant of burning quality.

In total, NEC and LG each have three drives in the Top10 list and Pioneer, Samsung, LiteON and Plextor each appear once in the list.

As we mentioned before, the report here gives information based on successful burns for each drive, for specific recording retries. The Plextor PX-716A grabs first place with a ratio of 96, while NEC ND-3520A, LG 4163B and LG 4160B share second place with a ratio of 94.

4. Most popular media type/brand

- Most Used media type

According to VSO users so far, the most popular DVD recording format is DVD-R, while DVD+R is close behind. With re-writable media, DVD+RW holds first place with 7.47%, while DVD-RW only has 2.40%. Users still cannot afford to pay for Double Layer media (DVD±R DL), since the percentage is rather low. Notice that the CD-R format is still very popular :-)

Buying cost is the main factor for choosing the DVD media brand, according to VSO results, and the answer for this is illustrated clearly in the following table. PRINCO DVD media holds the title of the most popular DVD media with 18.60%. CMC Magnetics (ID codes AE1 and E1), are also very popular, mostly because they are used for OEM business under various retail names, while both G04/G05 from RITEK are presented in the Top 10 used media. Verbatim media seems also to be strong with both +/-R media.

For the specific statistical sample, the most reliable media seems to be RICOH's re-writable media and Verbatim's 8X -R.

7. Summary

VSO Software has really made a clever move here, by supporting such an interesting feature. A reliable statistical analysis would require a large number of samples, regional information about users and of course, a prolonged testing procedure.

According to the current weekly results (11~17 April 2005), the most popular recorder is NEC's ND-3500A, while the most reliable recorders come from Plextor (PX-716A).

If you are looking for the most reliable DVD recordable media, Verbatim's 8X -R showed the highest ratio with 93 out of 100! The most popular DVD recordable format is DVD-R, followed by DVD+R. The high prices as well as limited availability of DVD+R/-R DL media, seem to be key factors in keeping users from using it. What we should say here, is that we do not have any regional information about the users that submitted the results. For example, submissions from Japan could lead to different conclusions, regarding the popularity of media hardware brands.

We are looking forward for the next additions to the database. CDRInfo plans to update this report on a weekly basis in order to present a more reliable picture of market trends. Stay tuned!
