Test machine:
For this review we will be using a computer with the following configuration:
Hardware:
- Motherboard: ECS Elitegroup N2U400-A with Nvidia nForce 2 Ultra-400 and nForce MCP chipset.
- Processor: AMD Athlon XP 2800+ (Barton) 333 MHz FSB.
- RAM: 1 GB Infineon PC2700 DDR
- GFX: ATI Radeon 9600 XT
- Sound: Onboard C-Media AC97
- Hard disk: Seagate Barracuda ST3250823A 250 GB
System set-up:
The Lite-On SHW-1635S was connected as Secondary Master and identified itself as LITE-ON DVDRW SHW-1635S. DMA (Direct Memory Access) and autorun was enabled for all devices.
Software:
Windows XP professional is installed on the computer along with Service Pack 2 for windows XP. We will be using the following software in this review:
Installation:
We quickly installed the drive without any problems and here is a screenshot from Nero InfoTool:
Our drive came shipped with firmware YS06, but was updated to firmware YS0B (see below).
The only drawbacks we could see are: the missing Mt Rainier support along with the small buffer size.
Features and techniques:
BookType (bitsetting):
The Lite-On SHW-1635S supports Bitsetting, and this feature can be controlled/changed with the Bitsetting option in Nero CD-DVD Speed, see below:
Error/quality scanning:
The Lite-On SHW-1635S supports error reporting just like earlier drives from Lite-On. Here are two examples on programs you may use for checking your written discs for errors.
KProbe is developed by a Lite-On employee, but it's not an official Lite-On program. This is what we use in our reviews.
Nero CD-DVD Speed is just as good and also gives you an indication of the quality by giving a score. Higher score is better; a good result should at least be over 80 in quality score.
8X DVD+R DL writing speed:
The Lite-On SHW-1635S uses Z-CLV, (Zone-Constant Linear Velocity) to write DVD+R DL at 8x. The average speed is 6.93x and total writing time is 17:13 minutes.
4x DVD-R DL writing speed:
The Lite-On SHW-1635S uses CLV, (Constant Linear Velocity) to write DVD-R DL at 4x. The average speed is 4.01x and total writing time is 27:43 minutes.
Introduction
It surely looks like CLV to me ... also the image says the same!
Very concerned about the dip during the 16x burns which results in a jump in jitter ... also overall high jitter, which usually mean poorly tuned writestrats and also lower disc lifetimes. Also - overall quality was shocking with some discs.
Wonder why you used a BenQ to scan? For speed only? I find BenQ tend to be less sensitive on some dyes (RICOHJPNR01 in my experience has less errors on BenQ than LiteOn) and heavily error on some others. Still trusting a LiteOn. Your efforts are appreciated a lot!
