FREECOM Fx-50 DVD+/-RW -
DVD reading tests
- Single Layer DVD-ROM (Click
for CDSpeed results)
All three drives support 12x maximum reading speed and use CAV reading strategy
for the single layer DVD-Rom. It is therefore not surprising that the performance
from all three drives was similar with the 820A Abex test DVD-ROM. The reported
drives is about 9.3x
The seek times for the Freecom and LiteOn dirves are similar for single
layer DVD-Rom, while the results for Mitsumi are slightly higher.
- Dual Layer PTP DVD-ROM (Click for
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 to the outer tracks for each layer.
The dual layer PTP DVD-Rom was read steadily, under CAV mode from Freecom
RW8J, and the test ended with very acceptable results. The reading process
at 3.53x and at the end of each layer reached 8.34x. On this test the Mitsumi
drive returned the slowest results.
The above graph shows that the seek times for the Freecom drive
are very fast although not the fastest in this comparison. The LiteOn drive
was the fastest while
the Freecom drive needed 91ms for Random seek and 173ms for Full seek. The
Mitsumi drive had the slowest seek times.
- Dual Layer OTP DVD-ROM
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
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.
All tested media up to now was read under CAV mode by the Freecom
RW8J drive, and the OTP DVD-ROM was no exception. The screenshot below
shows that the drive momentarily had to slow down speed at the end of the first
layer when switching over to the second layer,
while the screenshot on the left, shows low seek times and a good average speed.
- DVD Ripping Tests
We measured the DVD-Video ripping speed for the Freecom drive using the
latest version of DVD Decrypter. The DVD Video title is the "Matrix" pressed
DVD Decrypter reported that in order to use the Freecom RW8J for ripping,
we hade to set the region, and so we used Region 2. We ripped the
movie on the DVD-ROM to our hard disk. The above graph shows that Freecom and
LiteOn finished the process faster than Mitsumi. According to DVD Decrypter,
12:53 minutes to finish the test resulting in an average speed of 6.6x
- DVD Recordable / Rewritable reading Tests
The chart below shows the Nero CDSpeed average reading speed results with
the following media:
The above graphs shows the average reading speed of the three drives with
all four media types, both writable and rewritable. The end speed for the
Freecom drive was slower than
the manufacturers specifications for 8x maximum reading speed and its average
speed was restricted to 4.65x for both DVD-R and DVD+R. LiteOn showed similar
performance to the Freecom drive while the Mitsumi returned the fastest speed.
With the rewritable media, the Freecom drive returned the fastest
reading speed with DVD+RW media, while the DVD-RW media was
read at exactly
same speed with all drives.
