Nero CD Speed Benchmark Results

Nero CD Speed checked the speeds of the drives working with four types of media: a CD-ROM (enclosed with a computer magazine), Audio CD, and CD-R and CD-RW with data, written by the benchmarking CD Speed utility itself.

The Mitsumi and NEC that have the highest specified CD read speeds of all participating devices reached the promised 40x only on the CD-R. They are noticeably slower on the CD-RW and CD-DA. The rest of the drives show stable results reaching their maximum declared speed. Among other information gathered in the test we can point at the high CPU utilization coefficient of the Mitsumi on the CD-R disc. The drive from Ricoh becomes hungry for CPU resources at 8x speed, while Sony DW-U10A has 100% coefficient when reading CD-R and CD-RW at 4x and 8x speeds, respectively.

Advanced DAE Quality Test

This detailed test checks the drive’s ability to extract successfully soundtracks from audio disks. The test worked with a CD-R disk specially created by CD Speed for this purpose.

All drives come neck and neck in this test, with the exception of Pioneer DVR-104WB that did noticeably slower. Mitsumi DW-7801TE and NEC ND-1100 were the only ones that fell short of the 100% quality result because of numerous synchronization errors.

“On-the-fly” copying was limited by 12x speed for all the drives. Once again, Pioneer DVR-104WB was an exception, having performed slower than the others. Positioning precision of all drives that is determined by the offset parameter is rather average. Sony and Ricoh have poorest results here. As concerns extraction of specific auxiliary data, all drives were much alike: they all can read up the info from subchannel and cannot from leadout. The Sony and Ricoh were unable to read up the leadin data, but were the only ones to read CD Text.
