LG GGW-H20L (Blu-ray Rewriter/HD DVD-ROM)

By Vincent Chang - 7 May 2008

Blu-ray, HD DVD-ROM & DVD-ROM Benchmark

Blu-ray, HD DVD-ROM & DVD-ROM Benchmark

First, we start off with some figures to better understand the read capabilities of the LG GGW-H20L using Nero DVD Speed found on the latest Nero This is tested with two commercially pressed DVD-ROMs (a single-layer and a dual-layer), four recordable DVD media (DVD-R. DVD-RW, DVD+R and DVD+RW), a single layer commercially pressed Blu-ray movie (House of Flying Daggers) and a single layer commercially pressed HD DVD-ROM movie (Black Snake Moan).

While the read speeds for the Blu-ray media on the GGW-H20L did not reach its theoretical maximum, it was still a decent average of more than 3x on our test media. HD DVD-ROM read speed was lower but that was in line with its more modest read specifications. Notably, the CPU usage for HD formats were extremely low, which is good. However, reading DVDs had a higher CPU utilization rate than the typical DVD drive, which while not the best of news, were expected as this issue had similarly afflicted the GGC-H20L. Seek times on the average were also significantly higher on HD DVD, though it does seem to be a fluke given the other results.
