Lite-On IT was
kind enough to send us their 8x dual format DVD-Writer; the Lite-On LDW-811S. We
have pretty good knowledge with Lite-On drives, as we have reviewed several of
their drives earlier. Lite-On IT is one of the main players in the optical
market; Lite-On IT is actually just one part of the large Lite-On Company. The
Lite-On company produces a lot of different products: keyboards, power supplies
and optical drives is just a few of them. But let us concentrate on the Lite-On
IT as it
's them we are dealing
with.


Also thanks to
Memorex for providing some of the media used in this review.


Some Lite-On
history:

ADVERTISEMENT

In 1995
Lite-On gathered some elite scientist and engineers from ITRI (Industrial
Technology Research Institute) to start an optical storage research and
manufacturing business in Taiwan. Currently they have over 130 engineers with
Master & Ph. D. degrees in their Research & Development team, that are
dedicated to the development of their patented anti-vibration mechanical design,
advanced circuit design, firmware programming & performance tuning. The
Research & Development team achievement is a key factor that has ensured
their success in product development.


In 1997,
Lite-On established a large manufacturing facility in China enabling them to
provide optimum OEM/ODM support to all 1st-Tier PC makers, which further
demonstrated their success in the worldwide Optical drive market. Today, they
are among top-3 optical drive manufacturer worldwide, mostly due to attractive
pricing and quality filled products, along with large OEM contracts. They have
also received top brand name recognition in many regions. These achievements,
plus superb management visions and planning, enabled them to continue their
growth and profit even at times when the optical drive market experienced
"price-wars" and many optical drive manufacturers were
forced out.


In 1999, they
created LITE-ON Information Technology Corporation, another proud member of the
Lite-On Group, to concentrate on developing and manufacturing optical drives to
stay strong in the storage business. They are going to carry on the tradition of
developing optical drives to expand their research and manufacturing capacity to
new generations of products such as DVD drives, High speed CD-RW drives and
COMBO drives to stay strong in both the retail and OEM/ODM market.


At
9th July 2001 Lite-On IT signed a co-operation contract with JVC, a
famous Japanese electrical company, to be in alliance with each other. Two new
companies was established, one is the optical drives manufacturing sales
company, named as JVC LITE-ON IT Manufacturing & Sales, Limited (JLMS) , the
other is pick-up head developing & manufacturing company.


JVC is a
pioneer in development of key components of optical drives and consumer
electronics as well, Lite-On IT is excellent in volume manufacturing and
developing, also skilled in IT industry. That kind of strategic alliance would
benefit both companies.


If you have
read our previous Lite-On reviews you may already feel familiar with this
company information, so let us now take a look at the specifications of this
drive:

Specification
wise it seems to be a good competitor to drives like the Plextor PX-708A. Our
expectations for this drive is very high due to the fact that our previous
Lite-On drives have been very good performers, especially when considering the
price of the drives.


In this review
we will try to find out how good it really performs by taking it through several
extensive tests.


Test machine:
