DVD Read Tests
Like
the Lite-On SOHW-1633s we reviewed, the BenQ DW1620 does not have a rip lock
in firmware. What does this mean? Well, you'll get some excellent
read performance, which will, in turn, provide faster ripping as well.
Let's check out how well the drive handles both single and double layer discs.
1.

Single layer read tests were very impressive, coming just slightly short of
16x and averaging in at 12x. While these transfer rates were not quite
as high as Lite-On's 16x drive, it makes up for it with its lower seek times.
2.
CD-DVD Speed - Dual Layer PTP DVD

The
results with PTP discs were fairly impressive as well, coming in slightly
short of 8x maximum transfer rate. The seek times remained very low and
there was an improvement in CPU usage as well.
3.
CD-DVD Speed - Dual Layer OTP DVD

|
Transfer Speed
Average:
6.07x

4X: 68%

Read
performance with OTP discs was also impressive, hitting 8x transfer rates.
Seek times also remained low.
Overall, this is about as good as it gets when it comes to DVD read
performance and is an indication of just how good of a DVD ripper this drive
will be. We'll check out ripping performance a bit later.
4.
CD-DVD Speed - DVD-R, DVD-RW, DVD+R, DVD+RW
To
capture maximum transfer rates of recordable media, I gathered up some discs
of all formats. The results are shown in the table below.
8x seems to the the maximum transfer rate for
recordable media. Surprising though was the slightly better scores with
the -R/W format. Not a significant difference, but it is usually the
other way around.
