The User Interface navigation entry offers setting options in the Language, Disc info (DVD), Priority, and Colors areas.
The following setting options are available in the Language area:
|
Menu
Language
|
Specifies the language to be used in the program interface.
|
In the Disc info (DVD) area, you can select which information is displayed on the Benchmark tab on the main screen. This setting will only be available if there is a DVD in the optical drive. The following setting options are available:
|
Option button
Disc type
|
Shows the Disc type of the DVD.
|
|
Option button
Book Type
|
Shows the book type of the DVD.
|
The following setting options are available in the Priority area:
|
Menu
Priority
|
Selects the priority of Nero DiscSpeed. Each process in Windows is run with a defined priority. This priority defines how efficiently Nero DiscSpeed can access the computer’s resources, e.g. memory.
The following priority levels are available for selection: Low, Normal, High, and Realtime.
Set the priority to High to prevent your tests from being interfered with by other processes running concurrently on the computer.
|
In the Colors area, you can define the colors for the Benchmark tab in the main screen. The following setting options are available:
|
Menu
Theme
|
Selects the desired theme. In addition to predefined themes, you can also set colors with the costum entry. To manually edit a color, click the colored tile and select the color you want in the dialog box that appears.
|
|
Button
Background 1
|
Changes the basic color in the background of the graph area.
|
|
Button
Background 2
|
Changes the basic color for shading in the background of the graph area.
Only works when the Background 2 check box is enabled. Otherwise, the background of the graph area is displayed in one single color.
|
|
Button
Grid (primary)
|
Changes the colors for the coarse grid in the graph area.
Only works when at least one of the following check boxes is enabled: Show horizontal grid and/or Show vertical grid.
|
|
Button
Grid (secondary)
|
Changes the color for the fine grid in the graph area.
Only works when at least one of the following check boxes is enabled: Show horizontal grid and/or Show vertical grid.
|
|
Button
Speed
|
Changes the color for the graph curve that represents speed (write or read speed, depending on the test).
|
|
Button
RPM
|
Changes the color for the graph curve that represents the rotational speed of the disc.
|
|
Button
Buffer level
|
Changes the color for the Buffer level curve.
|
|
Button
CPU usage
|
Changes the color for the CPU usage curve.
|
|
Check box
Show horizontal grid
|
Shows the horizontal grid lines in the graph area or hides them. This box is checked by default.
|
|
Check box
Show vertical grid
|
Shows the vertical grid lines in the graph area or hides them. This box is checked by default.
|
| Disc type |
Disc type refers to different optical storage media with different specifications. The best known are CD’s and DVD’s that can be written to once or multiple times, and which are manufactured with different storage capacities.
| Book Type |
The book type defines the specification (e.g. DVD-, DVD+, DVD-ROM) of a DVD. In order to ensure correct playback, the DVD specifications are defined in books so that all media can be read correctly. The specifications are defined in the so-called Rainbow Books, which are distinguished by means of their color (e.g. Yellow Book).
| Write Speed |
The write speed indicates the speed at which a drive can write data to the optical storage medium, e.g. 8x or 16x speed.
| Read Speed |
The read speed of a drive is a factor of the speed that the laser needs in order to read the data on an optical storage medium, e.g. 8x or 16x speed.
| Rotational speed |
Discs can be read and/or burned in different ways. As a general rule, the reading process in optical drives starts at the radius of the disc and moves from the center outwards. The two standards used to define the types of rotational speed are linear velocity and angular velocity. With constant angular velocity, the tracks at the center of the disc always travel at the slowest linear velocity. The linear velocity increases as you move away from the center towards the outer edge. Angular velocity (also called rotational speed) describes the change in the rotation angle over time independently of the radius of the disc, i.e. the velocity at which an object loops a sector.
| Buffer |
A buffer refers to temporary memory that records and delivers data that cannot be processed immediately as required. The buffer also allows for continuous data flow.
| CPU usage |
The central processing unit processes a computer’s processes. The higher the computing performance, the higher the load of the CPU and its performance.
