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

First, we start off with some figures to better understand the read capabilities of the LG GGC-H20L using Nero DVD Speed. 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 and a single layer commercially pressed HD DVD-ROM movie.

Looking at the read speeds we got for both Blu-ray and HD DVD-ROM, they were up to the maximum specifications stated for this drive. The drive read DVD+/-R media only at a maximum of 12x so our results here were fairly accurate too. We also noticed a lower CPU usage rate of around 24 - 25% maximum for DVD media, as compared to the 45% on the last Blu-ray drive tested, the ASUS BC-1205PT. Like the other Blu-ray drives that we have seen however, the CPU usage numbers are far lower for Blu-ray/HD DVD-ROM than the normal DVD media. Access speeds were also rather typical, with only an uncharacteristic spike for Blu-ray.
