DVD Capabilities
Next we tried various flavours of
DVD disk, these included: DVD-R, DVD-RW,
DVD+RW, DVD+R, DVD-RAM and a pressed
DVD-ROM disk. This insured that the
drive was put to test with all the
common type of disks on the market.
DVD-R
Firstly we checked its performance
with a DVD-R disk with Nero DVD
Speed:

It gave a reasonable average read
performance of 5.90 X speed for DVD-R
disks.
DVD-RW
Next we tried a DVD-RW disk from
the competing "-" (minus)
format:

We did notice some strange issues
with DVD-RW disks - a few times the
drive wouldn't even give an accurate
table of contents for the disk and
we thought it might not be compatible
at all, but then it started working.
This is a poor result and it only
managed to read them at 2 x speed.
DVD-ROM
Pressed DVDs have the best reflectivity
due to their good pit and landing
definition made at the mastering plant.
This result should be the drives best:

The drive gave an average of 5.91
speed and manages its full speed of
7.89 X towards the end of the disk
(this is very close to the stated
8 X speed reading on the box).
DVD+RW
DVD+RW disks were out months before
the +R disks were and this test was
a good result for the drive:

It averaged 5.99 X speed and the
drive did even better in this test
than with the pressed disk, achieving
7.79 x speed on the outer surface
of the disk.
DVD+R
Surprisingly the drive reads the
+R disks a lot slower:

It averaged 2.89 X reading speed
(which was the best score out of the
3 +R disks we tried).
DVD-RAM
For completeness we checked how it
behaved with a DVD-RAM disk out of
its caddy (the Toshiba SDM-1612 DVD-ROM
can read DVD-RAM disks like this).
We didn't expect the drive to read
them and it didn't.
ERASING DVD+RW Disks
We timed how long it took to do a
FULL erase of a DVD+RW disk:

A full erase only took 23 mins and
19 seconds (compare this to a DVD-RW
disk's 57mins).
Quick Erase
The drive is very fast at erasing
DVD+RW in quick mode and only took
16 seconds to finish the job.
DVD CSS RIPPING
Next we examined the speed at which
the drive could rip movies with the
content scrambling system (CSS).
The ripping speed is often not revealed
by the manufacturers of DVD-ROM drives,
for example the Toshiba SD-M1502 is
a x16 DVD reader but it can only read
CSS disks at x2 speed.
There are legitimate uses for ripping
movies to the hard disk, for example
you might want to rent a DVD movie
and watch it at a later date. In this
case programs like CladDVD
XP or DVD
Decrypter will come in handy for
storing it to your hard disk.

Panasonic LF-D311 Rip Speed: 5.8

Philips DVDRW228k: 2.2 x
The drive had a slow average rip
speed of 2.2 X and the Panasonic in
this case is much faster.
