This test is intended to check the drives’ ability to read up physically damaged discs. We used a specially prepared disc with multiple scratches on the working surface. As you see from the table, absolute champions are Pioneer DVR-105 and DVR-105BK. The both were fast and didn’t make any mistakes during reading. Their analog, Pioneer DVR-A05, performed a little bit worse. Going on at the same speed, it produced 70 errors. Probably, it owes these errors to an older firmware version. Ricoh RW5125A and Teac DV-W50E do quite well, too. Their owners can rely on their ability to read a bad disc.
Pioneer DVR-104WB was the least successful of all in this test producing over a million errors at the slowest read speed. Moreover, it hung up as soon as it reached the second half of the disc. Mitsumi DW-7801TE and NEC ND-1100A, as well as both Sony drives were just a little better: they all produced quite a big number of errors, which can become critical in some cases.
Performance in Nero CD DAE
This test shows the ability of a drive to rip an audio disc into WAV files. For this test we used a licensed CD-disk. The results are listed in the table above.
There were no faulty drives, and they all performed at similar speeds, except Pioneer DVR-104WB. That’s quite predictable considering its lower speed characteristics. On the other hand, it consumed less CPU resources. All other models loaded the CPU equally.
