- CD Format
our CD transfer rate tests, we used the Nero CD-Speed utility and two different
media, one Pressed and one USRW. Let's take a look at how the drive performed
compared with the other two drives.
The BenQ drive supports up to 48X reading speed with Pressed CD media and
so was close to the performance of the LiteOn drive which is known for its reading
Once more, fast reading speeds from the BenQ drive, this time with USRW CD
For this tests we used a pressed AudioCD, as well as the Advanced DAE test through the use of Nero CD-DVD Speed.
The BenQ DW-1655 media supports a relatively high DAE speed. As the Advanced
DAE quality test reported, the Quality score was a perfect 100, while the reported
average speed was 33.15X. The drive supports CD Text, Subchannel Date reading
as well as Leadin, but not Leadout data.
- 90mins Audio disc
- 90mins Audio disc
The drive managed to finish reading both the 90 and 99 mins audio media. As
we can see from the above screen-shots, the 90 mins audio CD was read at around
7X average speed and the 99mins audio CD although reaching the maximum reading
speed, could not continue at this speed all the way to the end, where the drive
had some erratic speed changes but was nonetheless successful in reading the
- DVD Format
Let's have a look at how the drive performs with DVD media. A set of DVD media was used, both SL and DL.
Since all three drives support up to 16X max reading speed with SL media, all drives reported almost identical speeds.
The two layers of a PTP DVD-ROM disc are read sequentially with
the drive starting reading from the inner part of the disc, which is the beginning
of each layer, progressing towards its outer range. When reading PTP media,
the BenQ and Plextor drives reported the highest speeds, with the LiteOn being
slowest, due to its 8X max reading speed with DL media.
The 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 main
difference being the reading strategy 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 towards the inner part of the disc. Again, the
BenQ and Plextor drives were faster with almost identical speeds. There's very
little between the BenQ and Plextor drives with the various DVD-ROM formats.
With write once media, the reviewed drive dominates, reporting the highest
average speeds of 12.09X and 12.05X for DVD+R and DVD-R media respectively,
due to its supported speed of 16X for these formats. With re-writable media,
the BenQ drive was again fastest although speed differences between the reviewed
drive and the other two are negligible.
Good ripping speed was reported, with an average of 12559kb/s, placing it just behind the Plextor drive.
