DRW-22B2ST - SATA, 2Mb, 160 ms, without Nero
E-Green (Energy Green Engine)
ASUS E-Green Engine technology features the E-Green Mode, which automatically closes drive applications that are not in use to help conserve energy. This decreases CO2 emissions and help reduce the depletion of trees.
E-Hammer
E-Hammer allows you to permanently delete the data on writable disc (CD-R and DVD-R) formats. Once the data is deleted, it cannot be recovered or restored, and the optical drive will not be able to read the disc. This ensures data security, eliminates the hassle of scratching your old discs, and conforms with our commitment to environmental protection.
OTS (Optimal Tuning Strategy)
With OTS, the drive will perform a test before really burning which generate the optimal burning strategy automatically for the best burning quality.
AVRS (Auto Vibration Reducing System)
With AVRS technology, ASUS DRW-22B2STS provides high readability and playability. AVRS technology minimizes the spindle motor's vibration and the resonance between components, drives, and PC cases. It also minimizes the vibration and noise caused by the unbalanced mass of rotating machinery.
