you click the Start button on the main screen or the menu item Run Test > Selected. These
tests are run on the Benchmark tab. All tests are activated by default.
The following setting options are available:
Check box
Transfer rate
Adds the test to the standard test series. The Transfer rate test
measures the read speed
of data, i.e. the speed at which data is
read from a disc. If the disc inserted is blank, the test measures
the write speed
.
Check box
DAE quality
Adds the test to the standard test series. The DAE quality test
comprises two partial measurements.
Nero DiscSpeed 13
Nero DiscSpeed Options Window
Nero DiscSpeed 14
Check box
Access/Seek Times
Adds the test to the standard test series. The Access/seek times
test measures the access
or seek times of optical drives for discs
inserted in the drive in three partial measurements.
Check box
CPU usage
Adds the test to the standard test series. The CPU usage test
measures the percentage utilization of the CPU (central process-
ing unit) at various speeds (1x, 2x, 4x, and 8x).
Check box
Burst Rate
Adds the test to the standard test series. The Burst rate test
measures the maximum possible transmission rate from the opti-
cal drive to the computer.
Check box
Spin Up/Down
Adds the test to the standard test series. The Spin down test
measures how long it takes an optical drive to stop, while the
Spin up test measures how long it takes before the optical drive
can read data again after stopping.
Check box
Load/Eject
Adds the test to the standard test series. The Load/eject test
measures the time that an optical drive needs to load, detect, and
eject a disc.
Check box
Extra Read Tests
Adds the test to the standard test series. The Extra read tests
test series consists of three tests. One or more sectors
on the
disc are read with defined test samples.
Check box
Create data disc
Adds the test to the standard test series. The Create data disc
test is available in its classic version on the Benchmark tab and
as an advanced version on the Create Disc tab. You can use the
classic test to analyze the write speed and the rotational speed
.
You can use the advanced test to also measure the buffer
level
and the CPU usage
caused by the optical drive.
Check box
Verify data
Checks the data that was written on the disc during the Create
data disc test.
In the Speed area, you can define the read speed for the Transfer rate test and the write
speed for the Create data disc
test. Maximum speed is enabled by default; this speed is also
recommended for testing the optical drive and/or the discs under worst-case conditions. The
following setting options are available:
Option button
Maximum
Selects the maximum speed that an optical drive can achieve.
Option button
Current
Selects the current speed of the optical drive. This speed is not
influenced, and can be affected by other system settings, e.g. o-
ther software or the firmware
settings.
Option button
Selected
Selects the speed manually. Enter the desired value in the input
field.
Nero DiscSpeed Options Window
The following setting option is available in the Spin-up time area:
Spin-up time
Defines the spin-up time.
In order to stabilize the disc and the optical drive, Nero Disc-
Speed starts spinning the disc before the actual test starts. The
default setting here is 10 seconds.

Nero DiscSpeed Options Window
Nero DiscSpeed 16
You can define the settings for the graph in the Graph area. The following setting options
are available:
Slider
Test length
Defines the accuracy of the transfer rate test.
The higher the accuracy, the more detailed the graph is.
However, higher accuracy results in a longer test dura-
tion.

in the graph.
Menu
Maximum speedCD/DVD
Maximum speedCD/DVD
Defines the maximum value shown on the vertical scale
of the graph on the Create Disc tab if a CD/DVD is in-
serted into the optical drive.
To prevent parts of the curve from extending past the
edge of the graph area, we recommend that you choose
a value slightly above the maximum read speed of the
optical drive.
Check box
Show minimum/maximum
Shows the minimum and maximum speed values re-
corded during the transfer rate test.
In a normal curve, the lowest speed is the start speed
while the highest speed is the end speed. In an uneven
curve, the lowest recorded speed is displayed as the mi-
nimum value while the highest recorded speed is dis-
played as the maximum value.
Check box
Read test
Shows the read test curve in either high or low resolution.
Check box
Write test
Shows the write test curve in either high or low resolu-
tion.
The following setting options are available in the Write options area:
Area
Write mode
Selects the SAO (Session-At-Once) or TAO (Track-At-
Once)write mode for discs.
You can also enable the Overburn CD and Overburn DVD
check boxes in Session-At Once mode. Enter the exact da-
ta quantity in the corresponding input fields.
Area
Disc type
Enables burning simulation for either data or audio discs.
Check box
Buffer underrun protec-
tion
Enables protection against optical drive buffer underrun
.
Buffer underrun protection is enabled by default. We rec-
ommend that you leave this box checked.
Nero DiscSpeed Options Window
Nero DiscSpeed 17
Check box
Streaming
Streaming can more than double the write speed. However,
it can have a negative effect on the quality of the disc, sin-
ce the disc is not checked during the burn process and de-
fective sectors are not re-written.
This box is cleared by default, in other words verification is
enabled. If this check box is enabled, verification will be di-
sabled for DVD-RAM
and Blu-ray discs.
Check box
Direct overwrite
If this box is checked, rewritable discs will be directly over-
written without having to delete old data first.
If this box is not checked, a dialog box will notify you when
a disc containing data is inserted for writing.
Check box
Burning an image file
If this check box is enabled, Nero DiscSpeed will run
through the Create data disc test by creating an image file
(ISO or NRG).
If this check box is not enabled, Nero DiscSpeed will run
through the same test by burning binary data until the ma-
ximum capacity of the disc is reached.
Check box
Include test data
If this check box is enabled, additional information about
the test (information on the optical drive, the installed firm-
ware, and the burn process graph) will be burned to the
disc.

the test is repeated often. The test is run 100 times by de-
fault.

4.7 Disc Quality Entry
The Disc Quality navigation entry offers setting options for the quality test in the General,
QuickScan, Diagram Margins and Colors.
Nero DiscSpeed - Options - Disc quality navigation entry
The following check boxes are available in the General area:
Determing the speed
The speed the Disc Quality is tested, can change with the
choosed optical drive. The speed is connected to the recorder
model and the installed firmware. If the check box is active, Ne-
ro DiscSpeed automatically detects the speed, as soon as the
Disc quality tab in the main screen is selected. If this box is not
checked, the speed must be manually detected.
Nero DiscSpeed 21
Nero DiscSpeed Options Window
Nero DiscSpeed 22
Show error limits
Shows the intervals in the diagram of the graphical representa-
tion in colored graduations.
Depending on the optical drive model and the intervals at which
they occur, detected errors can be classed at a glance as per-
missible, tolerable, or unacceptable.
Show statistics
Shows a statistical overview of the results at the end of the test.
Show disc label
Shows the disc label on the Disc Quality tab.
In the QuickScan area you can define the options for the quick scan. The Disc Quality
could be executed as complete scan. You can choose between the quick and the full scan
on the Disc Quality tab. The quick scan only checks defined points on the disc. All other ar-
eas are ignored. As a result, it requires less time than a complete scan but is less accurate.
Measure points
Defines how many points on a disc will be checked during the
quick scan.
Sample Length
Defines the size of each scan point in MB.
In the Diagram Margins area you can define the maximum scale limits for the graphical rep-
resentation of the error curves. The following setting options are available:
Option button
Automatic
Automatically adapts the graduated scale values to the number
of errors measured. A value of 10 is defined as the initial value
for both C1 Errors/PI Errors and for C2 Errors/PI Failures.
If more errors are found, Nero DiscSpeed automatically adapts
the scales to the higher value.
Option button
Fix
Defines the maximum values on the scales as locked. Enter
the values you want in the C1 Errors/PI Errors and C2 Er-
rors/PI Failures text boxes.
Selection area
Maximum CD speed
Defines the maximum value that will be displayed in the C1 Er-
