48x CD-RW Combo Roundup Vol.1 - Page 3
Data CD Reading Tests
Both combo drives support 48x CAV reading for CD-ROM/R
media. Although the LiteOn drive started reading at a higher speed (24.18x)
than the Optorite DC4801 (22.62x), and reached the maximum speed
of 50.41x, the drives gave similar average reading speeds.
The Optorite drive reached the maximum supported 48x speed as
early as at the 72:00 min address of the disc, and read the rest of it at
48x. The reading
strategy resembles to P-CAV and thus, the average reading speed is increased.
Looking at the seek times with the same pressed CD, LiteOn
gave slightly better results on Full and 1/3 mode reading. The Optorite
drive is faster in the random seek
mode with only 91ms. Both drives performed well in this test.
When it comes to CD-R media, the transfer rate results are almost the
same as with respect to those for pressed CD's.
Optorite DC4801 was faster at the begriming of the test with a starting speed
of t 22.27x, while the LiteOn drive offered the highest ending speed
(50x).
The average
speed of both drives is almost
the
same, with LiteOn being a bit faster at 37.64x
In the seek times test, the LiteOn drive still offered
good results, as in previous test. On the other hand, the Optorite
drive was slower
in all the seek modes, and especially in the Full stroke test.
For
the HS-RW reading test we used
Mitsubishi Chemicals 24x US-RW media.
The Optorite drive is faster than the LiteOn, since it supports 48x CAV reading
with rewritable media.
LiteOn reached a maximum speed of 42.2x at the end of the task and thus the
average reading speed was 31.85x.
