PWL (Preemptive Wear Leveling) is a technique in which the drive arm frequently sweeps across the disk to reduce uneven wear on the drive surface common to audio video streaming applications.
The ultra cool, quiet drive is the perfect solution for a variety of multimedia applications and fan-less environments where the drive operates below 149°F (65°C) base casting temperature.
The noise levels have been minimized to less than 1 sone*, virtually below the threshold of human hearing.
*A sone is a subjective unit of loudness as perceived by a person with normal hearing
It is ideal for video surveillance, DVRs/PVRs, set up boxes, high-end audio systems, karaoke players and digital signage.
