Optorite DD0203 supports 12X CAV (5-12X)
reading speed for the DVD-ROM format. The drive finished the test with an average
reading speed of 8.81X. The Pioneer drive is faster in this test with 9.46X.
Sony DRX-500UL supports 7X CAV DVD-ROM reading so it gave the lower performance
in the same test.
The seek times of the Optorite drive are very
good. The random seek test gave an 101 msec result, and the 1/3 seek around
113msec. According to the CDSpeed software, the drive gave a 67msec result in
the full seek test. Of course, this result could not be valid for a DVD-ROM
seek and it is possibly a CDSpeed bug. Testing the full seek times with another
software gave the actual results, which is around 200msec.
- Dual Layer PTP DVD-ROM (Click for
The dual layer PTP DVD-ROM disc was read at 4.29x average. The reading speed
in the beginning of the disc was 3.88x and the ending speed was 4.32x. The
drive used the P-CAV reading strategy, as you can see in the CDSpeed link.
The two layers of a PTP DVD-ROM disc are read sequentially with the drive
to read from the inner part of the disc, which is the beginning of each layer,
towards the outer range, for each layer.
The Pioneer A05 was faster in this task with 6.12x average reading speed.
The Sony DRX-500UL is the slowest reader since it supports 2x CLV reading.
In addition, the seek test gave the Optorite DD0203 the best performance with
low seek times.
- Dual Layer OTP DVD-ROM
The first layer of an OTP dual layer DVD-ROM is read exactly the same way
as the PTP disc we tested previously. The difference here is the reading strategy
of the second layer of 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
toward the inner part of the disc.
The performance is not different than in the previous test, with the drive
to give a 4.29x average reading speed.
- DVD Ripping Tests
We measured the DVD Ripping speed using the "Matrix" DVD Video
title and DVD Decrypter software.
Optorite DD023 ripped the files to the hard disk at an average speed of
The performance is high, especially compared to the rest drives in the chart
- DVD reading Tests
The chart below shows the Nero CDSpeed results with the following media
Optorite DD0203 supports 4x CLV reading for all the DVD recordable/rewritable
media. The Sony DRX-500UL is slower (2x CLV), while the Pioneer A05 is faster,
since it reads the discs under the CAV reading strategy.
