There are many optical disc recorders and great number of brands that sell CDs or DVDs, and you shouldn’t count solely on a brand name when you require long term data reliability. You can verify written data in your favorite CD burning program, but it’s not enough. If you want to be sure in the quality of your home-written media, you need a program to test your optical drives and media.
One of the most popular programs for this purpose is Nero CD-DVD Speed that is part of Nero Toolkit.
Nero CD-DVD Speed is a powerful tool for testing optical drives.
The program has simple tabbed interface that is very easy to use. The first tab is called Benchmark. It allows you to check the read speed of a disc, DAE quality (for Audio CD), disc access type, access times, CPU usage at different speeds, and data interface burst rate.
After scanning a disc you will see the curve of reading speed. If this curve isn’t smooth, then you should worry about reliability of your media and written data quality.
Nero CD-DVD Speed allows you to perform test of writing performance of your optical drive (Create Disc tab).
On the tab “Disc Info” you can find such information about disc as disc type, manufacturer, write speed, number of layers, disc capacity, disc status and others.
One of the most important features of Nero CD-DVD Speed is its disc quality test. When this test is complete, you will obtain report about the discovered errors and will see two histograms that demonstrate the errors encountered. And finally Nero CD-DVD Speed calculates cumulative quality score. The higher this score, the better quality.
Nero CD-DVD Speed also includes a ScanDisc function with File Test & Surface Scan to check the integrity of the optical disc and allows to perform TA jitter test.
The are several others features such as overburning test, advanced quality DAE tests, etc.
Nero CD-DVD Speed supports for CD, DVD, Blu-Ray and HD DVD drives and media. And finally this good and very useful program is absolutely free.
The latest available version of Nero CD-DVD Speed is 4.7.7.15 that has been released recently.
