As always, we used three discs for this benchmark: a CD with CD Winbench 99 itself, and its CD-R and CD-RW copies.

Mitsumi DW-7801TE looks worst of all here, with low Winmark ratings on CD-ROM and CD-R discs. If the problems with the first medium, which we clearly see on the graph, are quite understandable, as some other drives had the same problems reading the first medium, the CD-R result was absolutely the worst. The graph indicates that the drive starts reading the CD-R with a constant linear velocity and then enters the constant angular velocity mode. NEC ND-1100A, Ricoh RW5125A and Sony DW-U10A also encounter difficulties reading a large portion of the CD-ROM. The Pioneers, TEAC DV-W50E and Sony DW-U12A show stable results on all types of media. The highest WinMark rating is given to the NEC drive on the CD-RW (and it is just slightly worse on the CD-R). Mitsumi DW-7801TE shows a similar result on the CD-R. But these two models lack stability.

All the drives show similar access time, except those cases when they are at a loss reading discs of a certain type. In this case the access time considerably increases.

CPU workload coefficient varied across the drives in a small range from 1.2% to 1.3%. The only exception is Sony DW-U10A that demands not that much from the CPU when reading the CD-ROM.
