DVD reading tests
- Single Layer DVD-ROM (Click for CDSpeed results)
In the DVD single layer read test, Teac performed almost identically and confirm manufacturers specifications for 16x reading DVD-ROM.
There isn`t a big difference on seek times.
- 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, which is the beginning of each layer, and progressing outwards towards the outer tracks for each layer.
Not a lot of difference between the drives. So far, quite good times from Teac.
Once more, the Teac drive was about the same with the drives with no remarkable difference.
- Dual Layer OTP DVD-ROM
The
first layer of an OTP dual layer DVD-ROM is readed 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.
TEAC reading the contents of this test disc, was fine. Reading starts at 3.39x and begins increasing in speed, until meets the start of the second layer. After that it starts decreasing the speed smoothly, until the end.
- DVD Ripping Tests
We measured the DVD-Video ripping speed of the TEAC DW-548D, using the latest version of DVD Decrypter. The DVD Video title is the "Matrix" pressed DVD-Video.
Teac proved very fast ripping the DVD title. Looking at the graph above, the speed of 8900kb/s attained is a very high transfer rate.
- DVD Recordable / Rewritable reading Tests
The chart below shows the Nero CDSpeed average reading speed results with DVD recordable and rewritable media.
The drive read DVDR+RW at 8x CAV, with no problems at all, starting at 3,5x speed. Same happens trying DVDR-RW. Both sets of test graphs are given in each case below.
