We used CDVD Benchmark, a program from German developers, to test the drives’ work with both CD and DVD media. So, we used a CD-ROM (enclosed with a computer magazine), CD-R and CD-RW with data written by Nero CD Speed, and a licensed audio disc. As for DVDs, we used a movie DVD-ROM and its copies written to DVD-R, DVD-RW, DVD+R and DVD+RW. Of course, we used only those DVDs for testing that were supported by a given drive.

We have already used CDVD Benchmark in our previous test sessions, but let’s add a few comments about its interface (for those who don’t know German). Each screenshot has two windows. The left window displays a yellow (white) line for the read speed and a green line for the spindle rotation speed. The right window displays the access time diagram: yellow dots stand for random access, while red dots indicate full stroke access. Below are the numerical results of the graphics representation, all in German of course, but you will have no problem understanding what the whole thing is about. For each drive you can see the read speeds (average, in the beginning and in the end) given in “X” and in KB/s. Besides, they also mention the working speed range of the given drive, the CPU utilization in percents at 1X speed, access times, burst data transfer rate. When audio CDs are tested, there is also some info about the drive’s ability to use “Accurate Stream” and “C2 error” pointers.

Now, let’s comment on the actual results. Mitsumi DW-7801TE practically hit its specified 40x read speed on the CD-ROM and CD-R, but was slower at reading the CD-RW and CD-DA (34x). As for DVDs, this drive only performed well on the DVD-ROM. The read graphs for the other two discs have irregular shape, especially the one for the DVD+RW. Maximum DVD read speed is 5x, falling short of the promised 8x speed.

NEC ND-1100A behaves much alike, showing 40x speed on the CD-ROM and CD-R and dropping it down to 34x on the CD-RW and CD-DA. DVD read speed didn’t exceed 5x. The drive had problems with the DVD+RW that look like big zigzags in the graph.

Pioneer DVR-104WB stands up to its word and reads CDs at 24x. DVD-R/-RW read speed is 2x, while DVD-ROM was read a bit slower than the specified 6x.

Pioneer DVR-105 feels confident at reading all four CD discs at 34x. It is higher than the specified 32x. This burner reads DVD-R and DVD-RW at a slightly higher than 2x speed, but in case of a DVD-ROM the speed exceeds 12x.

Its namesake, Pioneer DVR-105BK, behaves much alike, which is no wonder: the both are actually the same model with very little external differences. Still, unlike the other model, this one had a slump in the CD-DA reading graph.

The third model made on the same base, Pioneer DVR-A05, performs close to DVR-105. So, I don’t think you need any more comments here.

Ricoh RW5125A fully complies with its own specs. It demonstrates very stable performance with all CD media exceeding the nominal 32x speed. The same situation can be observed for all three DVD-discs: the read speed CD proved up to the claimed 8x.

The multi-functional Sony DW-U10A is stable at work with all CD media reaching 32x speed. As for reading DVDs, this model did well only on the DVD+RW (2.4x). With other discs, the read speed didn’t go beyond 2x.

The second Sony, DW-U12A, performs just like the first one. It is a variation of the DW-U10A model, so this result is quite expected.

Now, the last drive, Teac DV-W50E, showed high results with all CDs, reaching above its specified 32x speed. The situation with DVDs is much more diverse: 12x DVD-ROM read speed (slightly better than specified), 2x DVD “minus” read speed and 6x and 8x DVD+RW and +R, respectively.
