Cool - Cool operation results in the highest reliability, even in intensely hot environments such as digital video recorders. That's why these, the coolest on the market, are the drives of choice for the world's leading consumer electronics and PC manufacturers
Quiet - The technology that Tom's Hardware Guide called very fast and nearly silent is used throughout this family of drives. Our WhisperDrive technology minimizes noise to levels near the threshold of human hearing. To cut seek noise, SoftSeek technology streamlines read/write seeking algorithms, resulting in more efficient operation
