LaCie d2 DVD±RW DL external drive with Firewire

 

Whats inside the box?


On this page, we will take a look at what the drive came shipped with and take a look at the drive and its technology.

 

 

 

 

Contents of the box:

 

  • The external drive itself
  • FireWire 6-pin to 6-pin cable
  • Hi-Speed USB 2.0 cable
  • LaCie DVD Utilities CD-ROM (2)
  • Blank DVD+R Media
  • Quick install guide
  • Power supply and adapter cable (2)

The blank DVD+R9 DL media (Verbatim) was given to us separately by LaCie for testing purposes.

 

Now it’s time to take a look at the drive itself:

 

 

The drive has a black front bezel.

 

The LaCie d2 DVD±RW Double Layer uses a green LED light for both reading and writing. The blue LED light on the left is the power LED, but also functions for power ON/OFF.    

 

 

On top of the case itself, we see a deep imprint of the LaCie logo, giving it a 3D effect.

 

 

On the back of the drive, there are from the left: Lock slot (anti theft), ventilation outlet, 2 FireWire 400 interface connectors, a USB 2.0 interface connector and a power supply connector. (The only additional thing it could have, is Audio out connectors).

 

We connected the drive without any problems and here is a screenshot from Nero info tool:

 

 

 

Our drive came shipped with firmware 2.04, and this is the latest version available from LaCie. We miss Mt.Rainier support and a larger buffer size.

 

And another shot from Nero Burning ROM:

 

 

 

We do not really find anything alarming here, but Mount Rainier and a larger buffer would have been nice.

 

Now it’s time to take a closer look at the write technology used by the LaCie d2 DVD±RW Double Layer:

 

CD-Recordable:

 

 

The LaCie d2 DVD±RW Double Layer uses Z-CLV, (Zone-Constant Linear Velocity), to write at its maximum speed of 32X. The drive wrote the last zone at 32X and this gives an average speed of 27.35x. Two drives for comparison is found below.

 

 

 

The Philips DVDRW885 uses P-CAV (Partial-Constant Angular Velocity) to write at its rated speed of 24x. This gives an average speed of 23.05x.  

 

 

 

The Plextor PX-708A uses P-CAV (Partial-Constant Angular Velocity) writing strategy to reach it rated speed of 40X. This gives an average speed of 33.38x.

The LaCie d2 DVD±RW Double Layer got an average speed. It is not the fastest and not the slowest drive we have tested so far.

 

CD-ReWritable:

 

 

The LaCie d2 DVD±RW Double Layer uses CLV (Constant Linear Velocity) writing technology to write at 16X for CD-RW discs, the average speed is 16x. Below are some other drives for comparison.

 

 

The Pioneer DVR-107D uses Z-CLV, (Zone-Constant Linear Velocity), to write at its rated speed of 24x, this gives an average speed of 22.47x.

 

 

 

The Plextor PX-708A, with its P-CAV (Partial-Constant Angular V elocity) write speed of 24X for Ultra Speed CD-RW discs is among the faster writers, due to its high starting speed of 20.01x.

It used almost the same amount of time as the NEC ND-2500A,
just 4 seconds behind it.


 



8X DVD-Writing speed:



 



 


The LaCie d2 DVD±RW Double Layer uses Z-CLV, (Zone-Constant Linear Velocity) to write at 8x. It uses 3 zones to achieve 8x
speed; The first zone from 0-0,8Gb is done at 4x speed, the next zone from 0,8Gb
to 2,2Gb is done at 6x speed and the last zone from 2,2Gb to 4,4Gb is done at
8x. This gives an average speed of 6.80x.


 



 


 


The Philips DVDRW885 uses Z-CLV, (Zone-Constant Linear Velocity) to write
at 8x. It uses two zones to achieve 8x speed; the first zone from 0-0,4Gb is
done at 6x speed, the last zone from 0,4Gb to 4,4Gb is done at 8x. This gives an
average speed of 7.55x. This places the drive among the faster 8x writers we
know of. The reason why there are so many bumps in the transfer rate curve is
the OPC control used by the Philips drive, which is designed to measure the
writing quality and adjust writing strategy when needed.


 



 


 


The Plextor PX-708A also uses Z-CLV, (Zone-Constant Linear Velocity). The first
zone from 0-0,7Gb is done at 6x speed; the next zone from 0,7Gb to 4,4Gb is done
at 8x speed. This gives an average speed of 7.69x, look below to see a

The LaCie d2 DVD±RW Double Layer results are almost equal to the NEC ND-2500A. From the
chart above we see that LaCie used 51 seconds less then the BTC DRW1108IM which
also writes DVD at 8x with Z-CLV 3 zones.


 



Features and
techniques:






 


What is double layer recording technology?


 


Introduced by Philips and Mitsubishi Kagaku Media (MKM) in
2003, double layer recording technology offers two recordable layers on a single
DVD disc, providing nearly double the capacity of 4.7GB single layer DVDs. The
two individual layers are separated by a transparent buffer layer and are
accessible from the same side of the disc, so recording can occur completely
uninterrupted.


 


When a double layer disc is inserted into a compatible
drive, the laser will focus on one of the layers and attempt to read an ADIP
(Address in Pregroove) signal. From this signal, the drive is able to detect if
the disc is a double layer DVD+R disc, and which layer it’s focusing on. Once
the media type and layer are determined, the laser can adjust its range of focus
to read one of the two recordable layers.


 




 


What is AOPC (Active Optimum Power
Control)?


The LaCie d2 DVD±RW Double Layer is equipped with NEC’s own AOPC (Active Optimum Power
Control) technology, which adjusts the laser output in real time to obtain
maximum readability.


 


Book type (bitsetting).


The LaCie d2 DVD±RW Double Layer drive supports bit-setting, and will as default write DVD+R9 DL
media with DVD-ROM book type.


 


Here is how you could check if your discs are really
written with DVD-ROM book type:


 


Start DVDinfoPRO and click the Media button and you should
get something like this:


 



 


As we could see the disc Book type is DVD-ROM.



Another quick test is to start Nero CD-Speed and look at
the disc information:


 





This should also say DVD-ROM.


 



Included
software:






 


Now it’s time to look at the included software and comment
it if needed. Notice that we may not use the included software in our
performance testing part of the review.

Edition:


 



 





 



 


Roxio Easy Media Creator 7 DVD Edition is a relatively new
program and has a lot of features that will suit ever basic user’s needs; it
contains programs for creating most types of CD/DVD discs. Packet writing
program, media player etc. are also included.
