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:
- 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
- If you refuse to participate, no information is sent
- If you accept to participate, a small block of information
is posted at the completion of each burning sequence
- 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:
- open Regedit (click "Start" menu, then click "Run..." and type "regedit" and OK)
- browse key :
HKEY_LOCAL_MACHINE\Software\VSO\CopyToCD
- search Value "Web_media_stats" (REG_DWORD)
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.

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!
