DVD reading tests
- Single Layer DVD-ROM (Click for CDSpeed results)
After performing the Single Layer DVD-Rom reading test, Nero CDSpeed reports that the TEAC drive is the fastest among the three drives. The final reading speed for the TEAC is 12.45x and the reading strategy is CAV. As with the same test with CD media, there is very little between the drives.
The seek times for the TEAC DV-W58G are very good. It had the fastest seek times with a reported full seek time of 159ms and average seek time of 84ms.
- Dual Layer PTP DVD-ROM (Click for CDSpeed results)
The two layers of a PTP DVD-ROM disc are read sequentially, with the drive starting the read process from the inner tracks on the disc, where lies the beginning of each layer and progressing outwards towards to the outer tracks for each layer.
After the end of the Dual Layer PTP DVD-ROM test, we can see that again there is very little between the drives and while the TEAC drive was not the fastest, the speeds are quite satisfactory. The reported end speed for this test is 8.44x, which is slightly slower than 8.60x for the Sony drive which proved overall, to be the fastest drive among the three.
Just as with Single Layer DVD-ROM media, the seek times for TEAC are fast and was the fastest with all three seeks among the three drives. The drive needed 86ms for random seek and 164ms for full seek.
- Dual Layer OTP DVD-ROM
The
first layer of an OTP dual layer DVD-ROM is read exactly the same way as the
first layer of the PTP disc we tested previously. The difference here is the
reading strategy of the second layer on the disc. The beginning of the second
layer is located in the outer part of the disc, so the drive starts reading
from the outer tracks inwards towards the inner tracks of the disc.
The Dual layer OTP disc was not a problem for the TEAC DV-W58G drive. The average reading speed was 6.18x, while the end speed reached at the end of the first layer was 8.32x. There are some annoying glitches where both the disc's velocity and hence speed, took some tumbles during reading of the second layer. It remains to be seen if this proves a problem during our quality tests later on this review.
- DVD Ripping Tests
We measured the DVD-Video ripping speed for the TEAC DV-W58G using the latest version of DVD Decrypter. The DVD Video title is the "Matrix" pressed DVD-Video.
The graph above shows that the TEAC drive was not the fastest among the three drives for DVD ripping, but the ripping speed is reasonable.
- DVD Recordable / Rewritable reading Tests
The chart below shows the Nero CDSpeed average reading speed results with the following media:
The drive is specified as having a maximum reading speed of 6x with DVD±R/RW media, compared to the SONY DRU-530A's 8x, hence it's times are going to be below those of the SONY drive's, which happened to be the fastest in this test. NeroCDSpeed reports that the average reading speeds with the TEAC drive for all four media is a little above the 4.6x mark, while the reading strategy is CAV with all formats.
