40x Roundup Vol. 2 - Page
- LG GCE-8400B
LG GCE-8400B is one of the few drives that support the P-CAV 40x writing technology.
The drive supports 40x writing, 12x re-writing, 8MB Buffer and "SuperLink"
as the main buffer underrun technology. The maximum reading speed of the drive
is 40x (CAV), making it slower than its competitors. The exact supported writing
speeds are 8x, 12, 16x (CLV), 24x, 32x, and 40x (P-CAV). The re-writing speeds
are 4x, 10x and 12x. The drive doesn't support the Mt. Rainier format with current
firmware, but LG mentioned that a firmware upgrade should support it. There
are two versions of the same drive. One comes with a 8MB buffer and one with
a 2MB buffer. There has been lot of talk about this, and the bottom line is
that lower buffer means less cost for each manufacturer. The drive supports
RAW reading/writing with hardware EFM correction.
- 40x CD-R writing speed
The LG GCE-8400 supports the 40x writing speed with the use of the Partial-CAV
writing technology. Below it's the Nero CD Speed writing graph that illustrates
the use of P-CAV:
The drive starts writing at 20.30X and gradually increases its writing speed,
reaching the 40x (CLV) speed at 54mins. The use of P-CAV technology gives higher
average writing speeds and lower noticeable noise compared to Zone-CLV solutions.
The average theoretical recording speed is 33.41X, making it the faster
40x recorder around, according to the Nero CD Speed test. Real life recording
tests, showed slightly different results with various media.
With the use of some media, the drive lowers its initial recording speed, coming
to lower average writing speed (33.34X):
Lastly if you use Imation 80min 32x certified media you will notice a dropdown
in the recording speed as the following graph illustrates:
The LG GCE-8400B starts writing at 20.28X and increases the speed up to 32X.
At 66minutes detects problem and lowers its recording speed down to 24x to avoid
- The package
package supplied was the retail European version that includes: the drive itself,
a quick installation guide for Nero/InCD, a printed manual, a printed warranty
card in 5 languages, audio cable and mounting screws. The software supplied
with the drive was Nero v220.127.116.11 and InCD v3.23. The drive includes two years
of warranty for the European territory. The complete package is available at
€.... including 16% VAT. (s.r.p.). Notice anything missing? The retail
package doesn't include any CD-R or HS-RW media. LG's answer was that users
could easily find CD-R/RW media now days at low prices. Even this is correct;
we still feel that retail packages should come complete, including at least
The front of the drive includes LG, 'HS-RW' logos and the drive's features
- "40x/12x/40x". You will also find two leds (Read/Write), the eject
button and the headphone input jack/volume selector:
At the back of the drive we will find the usual connectors (IDE interface,
power), the jumpers for setting the drive as a Master/Slave, the SPDIF output
connector and the analog/digital output connectors:
The LG GCE-8400B was installed as Master in the secondary IDE Bus, worked
at PIO-Mode4 and under WinXP, DMA was activated automatically.
The drive is an April 2002 model with firmware revision v1.00 installed. A
newer firmware revision is already available (v1.01) and was installed for all
the recording/reading tests.
