Asus' new DRW-20B1S/B1ST DVD rewriter supports 12X DVD-RAM write, 20X DVD+/-R and 12X DVD+/-R double layer media sources. It also features Optimal Tuning Strategy ? a technology that automatically adjusts burning for optimum disc backups.
The ASUS DRW-20B1S/B1ST is equipped with the Optimal Tuning Strategy (OTS) that provides improved disc burning for better total write quality. With OTS, the drive will perform a test burning before really burning the disc, and OTS is intelligent enough to encompass both media and drive variations, as well as operating temperatures into its calculations ? allowing it to provide the optimal write speeds to produce the optimal burning strategy for the new disc. After the disc is burnt, OTS memorizes the particular type of disc, and will utilize the same burning strategy when the same type of disc is used.
Another new feature of the DRW-20B1S/B1ST is the E-Green Engine technology. This feature provides an E-Green Mode which activates when the drives are idle for 2.5 minutes. Once activated, drive applications are closed when not in use to help conserve energy.
The ASUS DRW-20B1S/B1ST offers both 20X DVD-Write and 20X DVD+Write. It also enables 12X DVD-RAM, 6X DVD-Rewrite, 8X DVD+Rewrite, 16X DVD-ROM single layer, 48X CD-R, 32X CD-RW and 48X CD-ROM capabilities.
Noise and vibration are two major headaches users encounter when using a high-speed drive. AFFMII is designed to change the uneven airflow field inside the drive to balance pressure distribution ? leading to quieter operations.
The AVRS technology is designed to minimize the vibrations caused by the spindle motor and resonance between components, as well as the drive and PC chassis. AVRS is designed to reduce vibration and noise induced by unbalanced mass of rotating machinery.
