Part of the model number, I believe it is an anti-vibration system.

From ASUS
AVRS (Auto Vibration Reducing System)

The AVRS technology is designed to minimize the vibration caused by the spindle motor and resonance between components as well as the drive and PC cases. AVRS is designed to reduce vibration and noise induced by unbalanced mass of rotating machinery. With AVRS, ASUS DRW-24B1 provides high readability and playability.
